PHP High Power Resistors Vishay / Dale PHP High Power Resistors have expanded to include new devices in compact 0603 and 0805 case sizes. The PHP High Power Resistors have enlarged backside terminations to reduce thermal resistance between the topside resistor layer and the solder joint on the user's circuit board. Other features include a resistance range of 10Ω to 30kΩ, wide temperature range up to 125°C, high power ratings up to 2.5W, resistance tolerance to ±0.1%, low absolute TCR of ±25ppm/°C, high purity ceramic substrate, and UL 94 V-0 flame resistance. Ideal applications include power supplies, power switching, braking system, test and measurement equipment, and motor deflection circuits.
