Pulse Safety Resistor

The pulse safety resistor boasts a wide range of rated powers, from 0.25W to 6W, and resistance values precisely spanning from 100mΩ to 1MΩ. This resistor is crafted using an advanced ceramic substrate, coated with a special composite film and further enhanced with explosion-proof multilayer coating that meets UL 94 V-0 standards.

It demonstrates exceptional surge resistance, effectively absorbing pulses directly or inductively cross-coupled in urban power lines, thus providing robust protection for electrical equipment or components from accidental impacts. Notably, the pulse safety resistor also serves as a cost-effective alternative to wirewound resistors, offering users a more economically viable solution.
