<h2>Overview</h2>
<p>The <strong>Dale RH-5 22 ohm 5W 1%</strong> is a metal-encased wirewound power resistor engineered for precision industrial and electronic applications requiring reliable current limiting and load balancing. This heat sink-type resistor combines wirewound resistive elements with a metal housing to deliver stable performance across temperature ranges and high-power circuit scenarios. Manufactured by Vishay (formerly Dale), the RH-5 series has become a standard in power electronics, motor controls, and signal conditioning circuits.</p>
