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

The PRL series resistors from Susumu have low inductance, and 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.

Susumu offers a family of current-sense chip resistors which have long side terminals to provide low equivalent series inductance. 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 equivalent series inductance of the PRL series is so small that high signal integrity is maintained without generating extra noise. 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.

The PRL devices are supplied in two configurations, with longer and shorter side terminals.
