Ohmite OY221KE Ceramic Composition Resistor
The OHMITE OX/OY Series of ceramic composition resistors are engineered for demanding applications requiring surge handling, high peak power, or high energy dissipation. These resistors are a robust alternative to carbon composition resistors, offering improved performance and reliability in high-voltage power supplies, R-C snubber circuits, and inrush limiters. The OY221KE, specifically, is a 2-watt resistor with a 10% tolerance, suitable for a wide range of industrial and electronic applications. Its ceramic composition provides excellent thermal stability and durability.
