Ohmite OX390KETR Ceramic Composition Resistor
OHMITE's OX/OY Series ceramic composition resistors are engineered for demanding applications requiring surge resistance, high peak power, or high energy handling. These resistors provide enhanced performance in high-voltage power supplies, R-C snubber circuits, and inrush limiters, often serving as a reliable replacement for difficult-to-source carbon composition resistors. They feature a 10% tolerance and are available in various ohmic values and wattage ratings, making them versatile for a wide range of industrial and electronic designs. The OX series offers 1W power rating while the OY series offers 2W.
