Vishay Thin Film
High Power Thin Film Wraparound Chip Resistor
FEATURES
* * * * * * PHP series chip resistors are designed with enlarged backside terminations to reduce the thermal resistance between the topside resistor layer and the solder joint on the end users circuit board. Actual power handling capability is limited by the end user mounting process. As with any high power chip resistor the ability to remove the generated heat is critical to the overall performance of the device. * * * * * High purity ceramic substrate Power rating to 2.5 W Resistance range 10 to 30 k Resistor tolerance to 0.1 % TCR to 25 ppm/C Flame resistant UL 94 V-0 Power supplies Power switching Braking system Test and measurement equipment Motor deflection circuits

Chip Surface Temperature (C)
Notes * Chip surface temperature measured using FLIR A40 thermal imaging system with an approximate test card surface temperature of 85 C. * Thermal imaging was conducted under ambient conditions resulting in a steady state test card surface temperature of 85 C over the full range of power levels. * Thermal imaging and load life testing was conducted mounting one device to 2" x 3" test cards with 2.5 mil copper plating on both surfaces. Thermal vias on 120 mil centers were utilized for heat transfer between surfaces of the test card.
