TPAL0220F500RK9

Through Hole Resistors

500 Ω±1%35 WTO-220thick filmnon-inductive

TPAL0220F500RK9 is a 500 Ω, ±1% TO-220 thick-film power resistor rated for 35 W when mounted to a suitable heatsink with flange temperature at or below 25 °C.

Best for

  • Heatsink-mounted power dissipation
  • Current sensing and load applications
  • RC snubber and energy absorption circuits

Avoid if

  • Applications without a heatsink above 2.25 W
  • Designs requiring verified lifecycle or compliance data beyond the supplied datasheet

Check before use

  • Flange temperature remains at or below 25 °C for 35 W operation
  • Heatsink and thermal-interface resistance
  • 500 V maximum working-voltage limit
  • TO-220 mounting dimensions and 5.08 mm lead pitch
