RT 100 Watt Mountable, Non-Inductive,
High Frequency Resistors
RT Non-Inductive design elements are ideally suited for high frequency and pulse load applications. By direct mounting on a heatsink significant cost advantages can be realized. RT (TO227) can be supplied in a 2-terminal or 4-terminal version. Double or 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.
