RTO Power Thick Film Resistors

Vishay's 20 W and 50 W resistors with wide resistance range of 0.01 Ω to 1 MΩ

Image of Vishay/Sfernice's RTO Power Thick Film Resistors 20 W and 50 WVishay’s RTO thick film power resistors feature a compact, easy-to-mount TO-220 package, which measures just 10.1 mm by 15 mm and, when mounted on a heatsink, provides a high power-dissipation-to-size ratio that enables high power ratings of 20 W and 50 W.

A special manufacturing technique includes ohmic adjustment through sand trimming, a process that avoids the generation of hot spots – such as those caused by laser trimming – and therefore reduces the risk of microcracks on each side of the curve. The resulting resistor features high reliability and stability while also providing good overload capability.

  • TO-220 package: Compact and easy to mount

  • Low thermal resistance down to 2.6°C/W
  • Non-inductive element

  • Industrial and medical power supplies
  • Test equipment
  • Power conversion
  • Current sensing
  • Snubbers
