Resistance Heaters

Resistors as Heaters Power resistors and resistance heaters share many common design considerations. In both products, good thermal design ensures low thermal resistance between the element and the exterior environment. Both must be rugged and reliable. Power...

Surge Resistors

What is a surge resistor? A surge resistor is a resistor installed in a circuit to prevent a “surge” when conditions arise where a surge might occur. There are a number instances where energizing a circuit is followed by a surge of current. Like almost all...
