PHP www.vishay.com Vishay Dale Thin Film High Power Thin Film Wraparound Chip Resistor FEATURES High purity ceramic substrate Power rating to 2.5 W Resistance range 10 to 30.1 k Resistor tolerance to 0.1 % TCR to 25 ppm/C Flame resistant UL 94 V-0 APPLICATIONS Power supplies PHP series chip resistors are designed with enlarged Power switching backside terminations to reduce the thermal resistance Braking system between the topside resistor layer and the solder joint on the Test and measurement equipment end users circuit board. Motor deflection circuits Actual power handling capability is limited by the end user mounting process. As with any high power chip resistor the TYPICAL PERFORMANCE ability to remove the generated heat is critical to the overall ABSOLUTE performance of the device.
