INTRODUCTION
These are TO220 high
voltage power film resistors. Internal structure of the resistor allows
4KV insulation. Mounted on a heatsink, usable power is 35W. These
models exhibit 3.3C/W
heat resistance. Compactness aids circuit design. Units also exhibit
excellent thermal
conduction, heat dissipation and vibration durability. Applications
include: ESD test bleeders
for SW PS, machine power units, motor control, drive circuits, cars,
measurements and industrial
computers.
