RESISTIVE POWER TERMINATORS
PTSM, PTWB SERIES
PTWB
W
The PTSM and PTWB series of Thin Film high power resistor terminators provide operating power to 2 Watts.
Tantalum
This is accomplished with Mini-Systems proprietary high current density Tantalum Nitride resistor film. Offered
in top contact, surface mountable half wrap, and full wrap terminations.
