30W TO-220 Planar Alloy Foil, Non-inductive Power Resistor

The TO-220 package features a resistor chip made of alloy foil material, which is suitable for low resistance ranges. It boasts a low temperature coefficient and strong pulse tolerance, making it ideal for applications such as current sampling circuits.

● Rated power of 30W at a baseplate center temperature of ≤25°C
● Transient current: I ≤ 200A (single pulse energy ≤ 20J)
● Standard TO-220 mold-encapsulated package with an exposed ceramic substrate
● Baseplate secured by M3 screws
● Standard lead configuration for easy installation; the resistor package is fully insulated from the heatsink.
