POWER-NIKKOHM
600W
CHASSIS MOUNTING NON-INDUCTIVE
HIGH POWER RESISTORS, DUAL

RPK600Features and Applications
Small size SOT227, 600W high power resistor. Attaching with a large forced air-cooled heat sink orliquid-cooling would be necessary for high power operation.
Rated power 600W (dual resistor at 25 °C flange temperature), single resistor configuration is available
in standard parts with 900W (at 25 °C flange temperature). Please see RPK900.
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.
