Ohmite OX270K 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 effectively replace carbon composition resistors, offering improved performance and reliability in high-voltage power supplies, R-C snubber circuits, and inrush limiters. The OX/OY series provides enhanced performance and are available in various ohmic values and wattage ratings, packaged in bulk or tape and reel configurations. They are RoHS compliant and operate effectively within a wide temperature range, making them suitable for diverse industrial environments.
