POWER SOLUTION - WILLOW TECHNOLOGIES LTD RoHS CHASSIS MOUNTING NON-INDUCTIVE HIGH POWER RESISTORS RPJ150, RPJ200 Features and Applications Small size TO227, 200W high power resistor. Attaching an air-cooled heat sink or water-cooling is necessary. Rated power is 200W (one element) or 150W (two elements). M4 screw terminals, very low series inductance. Higher density packing, vibration-proof and perfect heat dissipation possible. 0.5K/W thermal resistance. Applications include snubber resistors for power supplies, gate resistors, pulse generators, and high frequency amplifiers, dumping resistance of theater audio equipment of dividing network of loud speaker systems, etc. Dimensions G H F B Symbols A B C D E F G H (mm) 38+/-0.5 25+/-0.5 13+/-0.5 30+/-0.2 15+/-0.5 13+/-0.5 2-3.2dia. 4-M4.0 Note C E D A Schematics 4 3 4 3 4 3 4 3 4 3 1 2 1 2 1 2 1 2 1 2 RPJ200X RPJ200Y RPJ200Z RPJ150X RPJ150Y Willow Technologies Ltd.
