CRM2512 - Pulse Resistant Power Resistor

Electrical Characteristics

General Information

The Bourns^®CRM2512 Series is a thick-

Power Rating @ 70 °C

2 W

ﬁlm power resistor with a rating of 2

watts in a standard 2512 chip format.

This product has a very wide resistance

range making it suitable for different

applications in power supply circuits

including current sensing and inrush

current limiting.
