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 Sfernice’s 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).
