WHPC: Thick Film High Power Chip Resistors: Extra-High-Power Range

12 November 2021

Compact power – 1W in 0508 – 1.5W in 0612 – 2W in 1020

WHPC0508X, WHPC0612X and WHPC1020X are part of the WHPC series and offer an extra-high-power range of chip resistors. Featuring inverse geometry, these chip resistors have very high thermal contact with the PCB and low internal thermal impedance. As a result, it is possible to support two to three times conventional ratings for the same footprint, without relying on excessive PCB copper heatsink areas. The three WHPC types are fully AEC-Q200 qualified and offer a wide range of values from 1R0 to 1M0 and tolerances down to 0.5%.

Features

• Three inverse sizes
• Rating of 2W in 1020 footprint
• Rating of 1.5W in 0612 footprint
• Rating of 1W in 0508 footprint
• Tolerance down to 0.5%
• Robust thick film technology
• AEC-Q200 qualified

Benefits

• The use of a high-power density part reduces the PCB footprint required
• Low thermal impedance minimises the temperature rise and enhances reliability of the assembly
• High surge tolerance of thick film technology gives reliable product performance under surge circuit conditions

Ideal Applications

• Power supply
• Motor drive
• Actuator control
• Active capacitor bleed
• IGBT gate drive
