0603 / 0805 / 1206 / 2010 / 2512
Standard Power Derating Curve
High Power Derating Curve
Metal Foil Resistors can offer twice the power than general thick film.
Sizes from 0402~2512, 1%, 5%, resistance from 10m~200mohm, low TC of 50/100ppm. 1W in size of 1206, 1/4W in size of 0402
CSM series is constructed with a metal foil resistive element mounted on a ceramic substrate for excellent heat conductivity to enhance power. Metal Foil current sensing resistors meet the accuracy and stability on critical power management design. Better performance in small sizes such as 0402,0603 over thick film process, cost efficient for market competitiveness.
