Metal Foil Resistors can offer twice the power than general thick film.
Sizes from 0603~2512, 1%, 5%, resistance from 20m~200mohm, low TC of 50/100ppm. 1W in size of 1206, 1/2W in size of 0603
MF 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 over thick film process, cost efficient for market competitiveness.


  • High power rating up to 2 Watts.
  • Low TCR down to ±50 PPM/°C.
  • Current detecting resistors for power supply, Motor circuits, etc.
  • Superior mechanical and frequency characteristics.
  • Compliant with RoHS directive


  • Switching Power Supply, Over Current Protection
  • Voltage Regulation Module(VRM)
  • DC-DC Converter, Charger
  • Automotive Engine Control, Portable Devices etc
