CHASSIS MOUNTING NON-INDUCTIVE

HIGH POWER RESISTORS

RPK900

Features and Applications

Small size SOT227, 900W high power resistor. Attaching with a large forced air-cooled heat sink or

liquid-cooling would be necessary for high power operation.

Rated power is 900W (single resistor at 25 °C flange temperature), dual resistor configuration is

optionally available with 600W (total of dual resistors at 25 °C flange temperature). Please see RPK600.

M4 screw terminals, very low series inductance.

Higher density packing, vibration-proof and perfect heat dissipation are available.

Applications include snubber resistors, breeder resistor, power voltage divider, dumping resistor, braking

resistor for X-ray, MRI, Laser power source and etc.
