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 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).
