Industry’s smallest low-noise current-sense resistors offer ultra-low heat dissipation

June 26, 2025

Issue 1 2026

Susumu offers a family of current-sense chip resistors, the PRL series, which have long side terminals to provide low equivalent series inductance.

The PRL series resistors’ low inductance means that they produce very little noise to mask the current measurement signal. Use of the PRL resistors enables very accurate current measurements in protection and control circuits.

 

The PRL series resistors are ideal for use in high-frequency systems, in which unwanted noise generated by electronics components can impair signal integrity. The Susumu current-sense resistors also offer market-leading heat distribution and dissipation, resulting in a lower temperature increase as a proportion of applied power.

 

These Susumu devices are supplied in two configurations, with longer or shorter side terminals.
