CHASSIS MOUNTING NON-INDUCTIVEFLAT TYPE HIGH POWER RESISTORSRPL350Features and Applications
Flat type, 300W high power resistor. Attaching an air-cooled heat sink or water-cooling necessary.
Rated power is 300W (one element).
Custom resistance and power resistor network available.
Higher density packing, vibration-proof, insulation withstand voltage and perfect heat dissipation possible.
Applications include snubber resistors, surge protection, breeder resistor, filter resistor, dummy load, gateresistor, dumping resistor for power electronics, automotive electronics, pulse generators, high frequency
amplifiers, theater audio equipment, etc.
Note: RPL310 was alternated by RPL350.
