Vishay 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 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

backside terminations to reduce the thermal resistance

between the topside resistor layer and the solder joint on the

end users circuit board.

• Power switching

• Braking system

• Test and measurement equipment

• Motor deflection circuits

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.
