POWER SOLUTION - NIKKOHM
20A Current Shunt Chip Resistors
CS20, CS20J
Features
Surface mount, 12.8mm-5.0mm sized, 20 A rating currents, precision metal plate current shunt chip
resistors, 80 ppm/C TC and 1.0 % tolerance are in standard.
100A rush currents durability for 3 sec. is no problem.
0.5, 1.0, 2.0 and 5.0 milliohms are standard, please call factory about optional resistances values.
Zero resistance as jumper is available at same size.
Applications
High power DC/DC and DC/AC conversion circuit, intelligent power electronics modules of all industrial
switching power sources, AC actuators of electric automobile and AC motor control of air conditioning
electronics.
