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 W Vishay'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.
