RTOP www.vishay.com Vishay Sfernice Power Resistors for Mounting onto a Heatsink Thick Film Technology FEATURES 1 % tolerance available High power rating = 200 W Wide ohmic value range = 0.046 to 1 M Non inductive Easy mounting Low thermal radiation of the case Standard isotop case (SOT-227 B) Material categorization: for definitions of compliance please see www.vishay.com/doc 99912 This series of thick film power resistors include modules which can incorporate up to 2 different resistor values in the same SOT-227B package. Two types of terminations are available along with a 4 terminal device for measurement applications in the case of the single resistor version. This product range benefits from Vishay Sfernices experience in thick film power resistor technology i.e. high power: volume ratio, low tolerance or individual resistors and excellent overload capabilities (due to the trimming technique).
