3R-100
100Watt Mountable
Non-Inductive,High Frequency Resistors
3R-100(TO-227, SOT-227, ISOTOP) Non-Inductive design these elements are ideally suites for high frequency and pulse load
applications. By direct mounting on a heatsink significant cost advantages can be reailzed.
3R-100(TO-227) can be supplied in a 2-terminal or 4- terminal version double or max. 3- fold resistors are available. Main
applications are Variable speed Drives, Power Supplies, Control Devices, Telecom, Robotics, Motor Controls, Dynamic
Braking, and other switching designs, RF Applications, soft start.
