BC Components Product specification
Leaded ceramic multilayer capacitors Mono-axialTM series
FEATURES
•High capacitance per unit volume
•Low cost.
APPLICATIONS
These conformally coated axial
leaded capacitors are designed for
commercial and industrial
applications in four dielectrics,
NP0 (ultra-stable), X7R (stable) and
Z5U, Y5V (general purpose).
Applications include timing,
coupling/decoupling, signal
comparison and biasing.
Mono-axial™ capacitors are suitable
for automatic insertion equipment.
DESCRIPTION
The basic capacitor construction
consists of ceramic dielectric
materials processed into a tape
with a typical thickness range
from 0.025 to 0.076 mm. Metal
electrode patterns are applied using a
thick film screening process. Multiple
layers are stacked and laminated in
such a manner that electrodes are
alternately exposed when the pattern
is cut into individual chip capacitors.
The capacitors are fired through a
high temperature profile to mature the
ceramic and metal into a
homogeneous unit.
Metal end terminations are applied
and fired to provide electrical
connection between the individual
layers. Tinned leads are attached
using a solder. Encapsulation
consists of a moisture resistant gold
colour conformal epoxy coating that
meets the flame requirements of
“UL94V-0”
.
