Description
The FMK current sensing precision shunt resistor series is part of the new FMx resistor family from Isabellenhütte, This resistor series offers a chip size of 1206, very good long-term stability and low thermoelectric voltages. The available resistance values are 0.001Ω, 0.002Ω, 0.003Ω, 0.004Ω, 0.005Ω and 0.006Ω, with selection of tolerances of ±1% and ±5%, and temperature coefficient under <50 ppm/°C. The FMK series from Isabellenhütte also features a constant current of up to 60A (0.001Ω), power rating of up to 4W (at 70°C) and is suitable for both reflow and IR soldering. These resistors are designed to be AEC-Q200 qualified (status pending). Their operating temperature range is between -65°C and +170°C.
