Mechanical Schematic
Dimensions:
Unless otherwise specified,
all tolerances are ±
Inches
mm
.010
0,25
Weight .....................0.7 grams
Tape & Reel ..............1200/reel
Notes from Tables:
1. Unless otherwise specified, all testing is made at 100kHz, 0.1VAC.
2. Optional Tape & Reel packaging can be ordered by adding a “T”
sux to the part number (i.e P1166.102NL becomes P1166.102NLT).
Pulse complies with industry standard Tape and Tape & Reel
specification EIA481.
3. The “NL” sux indicates an RoHS-compliant part numer. Non-NL
suxed parts are not necessarily RoHS compliant, but are electrically
and mechanically equivalent to NL versions. If a part number does not
have the “NL” version, but an RoHS compliant version is required, please
contact Pulse for availability.
4. Temperature of the component (ambient plus temperature rise) must be
within specified operating temperature range.
5. The rated current (Irated) as listed is either the saturation current or the
heating current depending on which value is lower.
6. The saturation current, Isat, is the current at which the component inductance
drops by the indicated percentage (typical) at an ambient temperature of 25C.
This current is determined by placing the component in the specified ambient
environment and applying a short duration pulse current (to eliminate self-
heating eects) to the component.
7. The heating current, Idc, is the DC current required to raise the component
temperature by the indicated delta (approximately). The heating current is
determined by mounting the component on a typical PCB and applying
current for 30 minutes. The temperature is measured by placing the
thermocouple on top of the unit under test.
7. In high volt*time (Et) or ripple current applications, additional heating in the
component can occur due to core losses in the inductor which may necessitate
derating the current in order to limit the temperature rise of the component. In
order to determine the approximate total loss (or temperature rise) for a given
application, both copper losses and core losses should be taken into account.
Estimated Temperature Rise:
Trise = [Total loss (mW) / K0] (°C)
Total Loss = Copper loss + Core loss (mW)
Copper loss = IRMS x DCR (Typical) (mW)
Irms = [IDC + ΔI /12] (A)
Core loss = K1 x f (kHz) x Bac (Ga) (mW)
Bac (peak to peak flux density) = K2 x ΔI (Ga)
[= K2/L (μH) x Et (V-μSec) (Ga)]
where f varies between 25kHz and 1MHz, and Bac is
less than 2500 Gauss.
K2 is a core size and winding dependent value and is
given for each p/n in the proceeding datasheets. K0 &
K1 are platform and material dependant constants and
are given in the table below for each platform.

Take note that the component’s temperature rise varies depending on the system condition. It is suggested that the component be tested at the system level, to verify
the temperature rise of the component during system operation.
