Schurter USN 126 Chip Fuse

The USN 126 chip fuse from Schurter provides temperature sensitivity for overcurrent protection, as well as protection against excessive ambient temperatures.

Im0016884

SCHURTER’s USN 1206 chip fuse is designed to meet the ever-increasing challenges associated with packing density in power electronics.

  • Offers temperature-sensitivity suitable for both overcurrent protection and against excessive ambient temperatures
  • Requires current flow to blow, thus providing protection against overcurrent just as well as any conventional fuse
  • Protects power semiconductors against over-temperature
  • Current-time characteristic shifts as a function of ambient temperature, resulting in a specific trigger at a certain threshold value to be achieved with increasing temperature
  • 12 A current rated
  • Features high I2t values at 32V DC and slow blowing characteristic
  • Breaking capacity is 80 A at 32V DC and 170 A at 16V DC
  • Operating temperature range of -40-125 C (-40-257 F) 
  • Meets AEC-Q200 standard making it suitable for applications requiring the highest reliability under particularly difficult conditions (heat, vibration, mechanical and cyclic strength)
