SMD..FResettable SMD device, 60 V max.

  • size range 0,3 ... 3 A bei 20 °C
  • low resistance
  • fast time-to-trip
  • suitable for very-high-density board applications
  • CSA
  • EU ELV
  • EU RoHS
  • UL file

The low-ohmic device SMD..F on polymer basis has a positiv temperature coefficient (PTC). It is suited for protective functions of electronical applications within a voltage range up to 60 V. SMD..F offers functions seen in a fuse, and upon heating (e.g. through over currents or short curcuits) amplifies its resistivity from an initial low-ohmic resistor to a very high-ohmic resistor. SMD..F is immune to manipulation and resets after debugging.
