CURRENT SENSING RESISTORS
Product Details
A-H resistors are constructed with four terminal, isolated voltage and current connections (i.e. Kelvin Connection)making them suitable for very precise current measurements, current limitations and current regulation in powerunits, current sources and electronic loads. Other applications include: Current measurements in pulse widthmodulated(PWM) control circuits as in servo and stepper motors and solenoid driver circuits.GENERAL SPECIFICATIONSModel Resistance Load Capacity TCR [ppm/C](R>20mohms) Tolerance A-H (1, 2, 5, 22, 50, 100,200, 500)mohms(1, 2, 5, 10, 20,100)ohms 10W(with heatsink) <+-10ppm/K(20C t0 60C) 0.1(B)0.5(D)1(F) CHARACTERISTICS Values in [ ] mean change in ohmic value after testOperating Temp.
