Low Resistance Current Sensors

Susumu introduces the RL, PRL and KRL series

Image of Susumu's Low Resistance Current SensorsSusumu'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.

Applications

Any application that requires current sensing raw resistance resistors such as:

  • Protection circuits
  • Control circuits
Features
  • Smallest size for required wattage
  • Over-current protection by becoming open (PRL)
  • Good RF4 board compatibility
  • No hot sot and minimum temperature increase
  • Offered in two configurations - longer side terminal and standard shorter side terminal
  • Temperature cycle resistance (KRL Series)
  • Highest wattage for required size
  • Low ESL - low noise
  • Resistance range 1 mΩ to 100 Ω
  • Highest power for available space
  • Resistance tolerance as low as ±0.5%
  • Excellent current-surge tolerance
