The OX273KE is a fixed ceramic resistor from the OX series, specifically designed for circuitry associated with surges, high peak power, or high energy. It provides a resistance of 27 kΩ with a tolerance of ±10% and a maximum power rating of 1 watt at 70°C. This component features a maximum working voltage of 300V, can handle a single impulse of up to 50 Joules, and operates over a temperature range of -40°C to +220°C. Its robust characteristics make it ideal for demanding applications such as high voltage power supplies, R-C snubber circuits, and inrush limiters.
