Ohmite OX681KE Ceramic Resistor

The OX/OY Series of fixed ceramic resistors are designed for use in circuits involving surges, high peak power, or high energy demands. They provide reliable performance in high voltage power supplies, RC snubber circuits, and inrush current limiters. These resistors can often replace 1W and 2W carbon composition resistors, making them a suitable choice for applications requiring high energy density. They feature a 10% tolerance and are capable of handling high peak power levels.
