RESISTORS, TERMINATIONS
High Power Chip, Aluminum Nitride – 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 RF power capability. Aluminum nitride
is used for those applications where the use and disposal of
beryllium oxide is a concern.

T
1. Resistance value is expressed using military 4-digit call-out.
50R0 = 50 Ohms
1000 = 100 Ohms
L
Other values from 10–500 Ohms may be available as special order.
Contact factory for availability.
2. Tinning with Sn96 “Lead Free” high temperature solder will maintain RoHS
compliance.
3. The “L” and “T” dimensions are for the bare substrate, and do not include
terminal thickness or tinning thickness.
