High Power Thin Film Wraparound Chip Resistor
PHP
Vishay Dale Thin Film
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.
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
• Power switching
• Braking system
• Test and measurement equipment
• Motor deflection circuits

Chip Resistor
Notes
• Chip surface temperature measured using FLIR A40 thermal
imaging system with an approximate test card surface
temperature of 25 °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.
Notes
• Chip surface temperature measured using FLIR A40 thermal
imaging system with an approximate test card surface
temperature of 25 °C.
