SERIES PPC, NPC
RESISTORS, TERMINATIONS
High Power Chip – 50 & 100 Ohms
GENERAL INFORMATION
When mounted on an appropriate heat sink, these chip devices
provide high power dissipation in terminations and as balancing
resistors in Wilkenson power divider networks. Laser trimming
provides maximum peak and average R.F. power capability.

1. The “L” and “T” dimensions are for the substrate only and do not include
terminal thickness or optional tinning thickness.
50 Ohms
2. Thermal Resistance (R°) is measured in °C/W between resistive film and
mounting surface.
TYPE W
(Note 3)
T
or
100 Ohms
3. The CW power rating is based on maximum film temperature of +150°C and with
maximum heatsink temperature of +100°C. Power is based on infinite and ideal
heatsink. Type “W” termination style does not have full back plane metallization
and typically handles 1/10 the rated power.
