RT-RL resistors

They offer enhanced performance in high voltage power supplies, R-C snubber circuits and inrush limiters.

In pulsed applications, these compact resistors distribute the energy uniformly throughout their structure, resulting in low thermal stress. The result is increased reliability, and in many cases reduced size, compared to wire or film types.

The solvent-resistant epoxy coating allows operation in almost any environment, and the choice of axial or radial lead construction offers convenient use.
