Current Sense Resistor

Current Sense Resistor Overview

Bourns Inc.

This presentation will discuss the functions of current sense resistors and review the product offering in the product selection guide. Power considerations and temperature concerns will be reviewed, as well as methods for properly measuring the resistance of these devices. The PWR4412/13 series will be highlighted as examples of how the resistors are designed for a wide range of environments and varying ambient temperatures.
