Vishay / Sfernice RCEC 500 / RCEC 750 Power Resistors

Vishay / Sfernice RCEC 500 / RCEC 750 Power Resistors are cooled by auxiliary heatsink thick film technology and offer a 500W or 800W power rating. RCEC 500 resistors feature thick film technology deposited on ceramic, a cold system without external radiation, and a high power / volume ratio. RCEC 750 resistors offer a system without radiation, a high power / volume ratio, M4 screw-on outputs, and an easy assembly with a self-calibrated pressure of 400N. Vishay / Sfernice RCEC 500 / RCEC 750 Power Resistors are non-inductive and have a wide operating temperature range of -55°C to +155°C.
