Resistors

50 Ω±1%35 WTO-220thick filmnon-inductiveheatsink required

TPAL0220F50R0K9 is a 50 Ω TO-220 non-inductive power resistor rated for 35 W only when its mounting flange is held at or below 25 °C using suitable heatsinking.

Best for

  • Heatsink-mounted power dissipation
  • Current sensing and energy absorption circuits
  • Industrial power electronics

Avoid if

  • A heatsink cannot maintain the flange at ≤25 °C
  • Required dissipation exceeds 2.25 W without heatsinking
  • An established lifecycle status is required

Check before use

  • Verify heatsink thermal resistance and interface material.
  • Measure flange temperature under worst-case load.
  • Confirm voltage, resistance tolerance, and pulse conditions for the application.
