SMPS - Switch Mode Power Supply Filter Capacitors
Today's high frequency switch mode power supplies (SMPS) require
high performance capacitors in the input and output filters. Union Technology
has developed a line of MLCC SMPS filter caps with extremely low equivalent
series resistance (ESR) and low equivalent series inductance (ESL) that offer
improved performance at higher frequencies. These capacitors have been
extensively tested and have performance characteristics meeting the demands
for efficient capacitors in these stringent applications.
Union Technology is approved to DSCC Drawings 87106 and 88011. Parts
can be screened to the requirements of MIL-PRF-49470 or customer drawings.

Notes:
1. Dimensions are in inches.
2. Unless otherwise specified, tolerances are
+ .010 inch (0.25 mm).
3. Lead frame configuration is shown as typical above the
seating plane.
4. See Table I for specific maximum A dimension. For maxi-
mum B dimension, add .065 inch
(1.65 mm) to the
appropriate A dimension. For all lead styles, the number of
chips is determined by the capacitance and voltage rating.
5. For case code 5, dimensions shall be .100 inch (2.54 mm)
maximum and .012 inch (0.30 mm) minimum.
6. Lead alignment within pin rows shall be within + .005
inch (0.13 mm).
