HIGH POWER CHIP, ALUMINUM NITRIDE
RESISTORS, TERMINATIONS
SERIES ANC
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
Wilkinson power divider networks. Laser trimming provides maximum peak
and average R.F. power capability. Aluminum nitride is used for those
applications where the use and disposal of beryllium oxide is a concern.

PERFORMANCE SPECIFICATIONS
Notes:
1. The “L” and “T” dimensions are for the substrate only and do not
include terminal thickness or optional tinning thickness.
2. 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.
