Ohmite offers circuit and equipment protection from large energy surges associated with lightning strikes, grid fluctuations, and defibrillator discharges. The OX/OY series offers great protection from large single surge events. The Ohmite TFS series is a constant wattage resistor that can take in-rush surges while maintaining resistance stability.

The OX/OY Series of fixed ceramic resistors are ideal for circuitry associated with surges, high peak power or high energy. They offer enhanced performance in high voltage power supplies, R-C snubber circuits, and inrush limiters. The OX/OY resistors can often replace carbon composition resistors which can be difficult to source. The OX/OY series can handle 50 joules and 80 joules of energy for a single impulse respectively with high impulse voltage handling.
