Bourns Riedon™ power resistors

Bourns is pleased to announce the introduction of Riedon™ power resistors by Bourns. The Model HPP, MS, MSR, MT, SF-2, SSL, UAL, UB, UT, UV and UW series are included in this release. With multiple technologies available, these power resistors span multiple application sectors by providing reliable, rugged, and precise resistors.

Included in the product introduction are wirewound resistors in through-hole and surface mount packages along with surface mount metal film and bare/coated metal element resistors. These technologies offer high power ratings, low temperature coefficients (TCR), and wide resistance and temperature ranges.

Applications such as battery energy storage systems, industrial power supplies, motor drives, smart meters, and current sensing will benefit from the breadth offered in the Riedon™ power resistors by Bourns product series.
