HDP247 resistor handles 120W at 25C and is rated up to 500V; the FDP220
handles 60W at 25°C and is rated 300V; and the HDP126 handles 30W and is
rated 300V. The parts are available in values form 0.05 to 10,000 Ω
specifications include a dielectric strength of 750V min with 1,000V
ratings available, a TCR of 100 ppm with 50 ppm optional, and an
operating temperature range0f –55 to 200°C.
The HDP high-density power
resistors use a proprietary fliming process that allows them to handle as much as two to three times the typical wattage found in similar package sizes.
