Low Resistance Current Sensors

Digi-Key introduces the RL, PRL and KRL series

Susumu's RL series current sensing resistors are some of the world's smallest chip current sensors per wattage due to the patented heat dissipation design. The long-side terminal type boasts low ESL and very small signal noise in high frequency applications.


RoHS Compliant Any application that requires current sensing raw resistance resistors such as:
  • Protection circuits
  • Control circuits
Susumu Co. Ltd.'s RL Series - Low Resistance Current Sensors
