High Current Power Shunt Resistor

For high current applications, KOA has now expanded its existing Power Shunt series by adding the PSJ2 and the PSL2.

The PSJ2 (3920 inch) resistor can measure currents up to 244 A (200 µOhm).

Constructed using a solid metal alloy resistance element with copper terminations the device provides superior corrosion and heat resistance and has excellent pulse resistance.

The PSJ2 and the PSL2 have a…

led driver current const regulated

The TSCR4xx are Constant Current Regulator (CCR) for linear LED driving.

The devices regulate with a preset 10mA nominal that can be adjusted with an external resistor up to 300mA (TSCR420CX6/TSCR421CX6), respectively a preset of 0.1mA (TSCR400CX6) and 20mA (TSCR402CX6) nominal that can be adjusted with an external resistor up to 65mA. They have been designed for driving LEDs in strings and will…

Wide Terminal Chip Resistor for Automotive

KOA's automotive current sensing chip resistors with wide terminations now achieve T.C.R. ±75ppm/K.

KOA’s new WU73-series, available in size 0612 inch and in the resistance range 10 mW to 100 mW, is suitable for current sensing and offers a better T.C.R. compared to the standard wide terminal series.

The better heat dissipation due to these wider terminals helps to save board space. The high…

Approved Wirewound Fusing Resistor UL1412

The new CFWS-series of fusible power wirewound resistors is now available from KOA.

In normal operation the CFWS series resistor acts as an inrush current control resistor but will safely fuse in specified power overload cases.

The CFWS series is available with 3W or 5W power ratings. Both power ratings are approved to UL1412.

Features:

  • Approved by UL1412 (File No.: E134679)
  • Flame retardant…
