PULSE SPECIALTY COMPONENTS
Hundreds of standard-model power transformers.
Nearly limitless custom-design choices.
The hundreds of catalog power transformers
described in this catalog (pages 4 through 13)
make up just a small portion of the magnetic
solutions available to you from Pulse Specialty
Components. Our custom design library includes
hundreds of power and signal magnetic compo-
nents built to unique customer requirements.
Does the transformer you require closely resemble
but differ slightly from one of our standard models?
Chances are we’ve built it before, and can quickly
do so again. A quick modification might include any
of the following:
nFrequencies up to 500 kHz
nSpecial input and output voltages
nCustom termination: connector, lead,
line cord, lug
nOptional mounting: surface mount
or thru-hole technology; chassis mount,
angle bracket, welded plate
nPC-board mounts using square, round or
rectangular pins; custom pinout configurations
Perhaps your application calls for more than a
modification. And you can’t design it yourself with-
out knowing the best alternatiives. We do. Custom
design is a Pulse Specialty Component strength.
Special-purpose bobbins, epoxy encapsulation,
insulation, magnetic wire, terminations-- all are at
our disposal and we build to suit -- to your require-
ments and to those of CSA, UL, VDE, and applica-
ble MIL specifications.
Once designed, we build our custom transformers
by the scores, hundreds, or thousands, in any of
five ISO 9000 approved manufacturing facilities
located in the US and abroad. Just as you need, we
design, build, and ship your custom Pulse Specialty
products on schedule, quickly and economically.
A wide selection of standard-model power transformers;
see pages 4 through 13 of this catalog.

PULSE SPECIALTY COMPONENTS
We also design and build subassemblies --
practically any component that involves a core
and a winding. On the power side up to 12-gage
wire and 1 kVa; on the signal side down to 46-
gage wire and serving application frequencies
beyond 1 GHz.
What we do best.
Few manufacturers can compete successfully in
both low-quantity custom and high-quantity
areas. Manufacturers typically do one or the
other well. Pulse Specialty Components does
both well thanks our domestic and offshore
design and manufacturing resources.
It all starts here, with extensive design engineer-
ing capability and well established domestic man-
ufacturing accustomed to building to commercial,
MIL, avionics, and space application require-
ments. Domestically, we’re well-equipped to fill
low- to mid-volume standard-part and custom
orders and to perform quick modifications of
standard parts. For higher-volume requirements,
our design engineers shake hands with our man-
ufacturing engineers in any of three offshore ISO
9000 manufacturing facilities owned and operat-
ed by Pulse.
The result is a rare combination: accessible and
talented customer service people and design
engineers supported by
a choice of
manufactur-
ing facilities worldwide.
Domestic or offshore, our prototyping, pricing,
scheduling, and delivery come together as if we
were all in the same facility.
nAccessible, experienced design services.
nRapid modification of standard models.
nQuick design/build of fully custom magnetics.
nLow- and high-volume manufacturing.
nExcellent pricing over a broad range of
supply requirements.
Wound toroids, 0.5 to 3 in. OD
#8 awg -- #46 awg
Assorted custom magnetic
components and configurations.
Current transformer modules.
MIL/high rel and commercial.
One- and three-phase.
Custom mounting.

PULSE SPECIALTY COMPONENTS
MIL-STD-1553 data bus couplers
Pulse Specialty Components single and multi-stub MIL-STD-1553 data bus
couplers range from lightweight and compact models for aircraft to heavy duty
models used in the M1A2 tanks. Ruggedly constructed full-military models include
our fully tested MIL-PRF-21037/27 coupling transformers inside. Economical cou-
plers for bench-test and other COTs applications also available. Custom designs
encompass a wide selection of connectors and box configurations. Standard
(to specification) and custom testing is available over a wide range of tempera-
ture, vibration, EMI, and other conditions.
MIL-PRF-21038/27 pulse transformers
As “Technitrol Components Division,” we were the first to achieve QPL status for
MIL-STD-1553B interface transformers. Our comprehensive QPL transformer
product line recently increased substantially in size to accommodate the new
three-tier product levels called for by MIL-PRF-21038/27.
We also were the first to achieve QPL status on surface-mount MIL-STD-1553
pulse transformers. To this day, many manufacturers experience difficulties pro-
ducing components that can survive the high-heat rigors of surface mounting and
still provide the performance, reliabliability, part-to-part repeatibility, and lifespan
required by high-rel military and commercial applications.
Custom models include low-profile single and dual, vertically-stacked dual,
and hermetically sealed transformers. Special test regimens and custom marking.
Delay lines
One of the most extensive selections of active and passive delay lines for military,
industrial and commercial applications. We are an approved QPL listed supplier
for MIL-PRF-83531 and MIL-PRF-83532. Our active delay lines can be manufac-
tured with integrated circuits from several logic families screened to MIL-STD-
883. Many delay lines are available in various package styles including single in
line (SIP), dual in line (DIP) and a wide variety of surface mount configurations.

for signal applications.
High Frequency Balun Adapter for 150-ohm Fibre Channel,
100-ohm Gigabit Ethernet, and 78-ohm high-speed 1553.
These wide-band baluns provide the impedance matching and isolation necessary
to interface a 50-ohm grounded test instrument with a differential circuit under test.
They convert a balanced differential-mode signal to a grounded unbalanced 50-ohm
signal with less than 2 dB insertion loss and greater than 15 dB return loss from
1.0 MHz to 1.2 GHz. This permits accurate and repeatable measurements of
signal quality, such as insertion loss, transmission loss, and return loss. Each
balun has a terminator network and correlation data for periodic calibration verifi-
cation. Terminal pins to connect the network under test to the balun are included.

PULSE SPECIALTY COMPONENTS
Fibre Channel and CMI line interface products for
today’s fastest LAN and WAN applications.
Bi-directional fiber (NRZ) to copper (CMI) converter
Built for E4/STM-1/OC3 applications to conduct bi-directional cross
media data, voice, and video communications at fiber speed data rates.
These modules provide all connections and signal conditioning for
NRZ/CMI network junctions Besides the signal connections, all that is
required is 12Vdc power. Very low transmit/receive jitter. Loss of signal
detection. Maximum operating distance exceeds 200 meters on 75
ohm RG-6/u and RG-11/u coaxial cable. Compact and easy to install.
SONET/SDH (CMI) serial line interface modules (LIM)
Compact, one-package line interface units for interfacing to the most widely used
SONET/SDH chip sets for E4/STM-1 applications.
CMI transceiver line interface modules offer a convenient, one package, high perform-
ance solution for the complex chip interfacing requirements of CMI applications. The
compact packages include transformer coupling for both TXand RXfunctions, an equaliz-
er, a differential amplifier, and buffering for ECL level input and output. Designed to be
inter-operable with existing ECL fiber transceiver drivers, the transceivers meet
SONET/ITU-T requirements for coded mark inversion (CMI) data transmission over cop-
per. The transceivers function equally well in both 311.04 Mb/s SONET STM-1 CMI and
278.528 Mb/s SONET E4 CMI applications, delivering fiber speed data transmission and
reception over more than 200 meters of 75 ohm RG-6/u or RG-11/u coaxial cable.
Fibre Channel serial line interface modules (LIM)
Designed to be inter-operable with existing ECL fiber transceiver drivers, these fibre
channel copper transceiver line interface modules drive high frequency (fiber speed) sig-
nals over copper media and offer high clarity over extended distances.
Passive (non-buffered ) transceiver models serve short haul applications of 10 to 30
meters over shielded twisted pair (STP), twinax, mini coax, or video coaxial cable.
Active models with buffered “receive” are built for long haul applications where losses
accumulate and diminish (receive) signal strength. Active models require a minimum
input signal of only 100 mV (from cable) to transceiver RX.
Two-way active models with buffered “receive” and buffered “transmit” are used in
long haul applications to recondition the signal to theappropriate drive level. Transmitter
output signal level is 1100 mV minimum.
Achieve fiber speed data and communications
over 100+ meters of copper.
Fibre Channel (SAN) dual transformers
Designed specifically for point-to-point coupling to 150 ohm twinax cable. The isolation
transformers protect the station from static charges that may develop on the cable and
prevents ground loop currents from being transferred between stations. The devices have
also been designed to provide common mode rejection within the transmission band and
thus reduce EMI.
The wide bandwidth of these devices minimizes data dependent jitter by providing fast
signal rise times. Low-end bandwidth also minimizes base-line wander, another contribu-
tor to jitter. The dual package allows connection of both the transmit and receive channel.
