501 Series Fuse

Littelfuse's 501 series high current 1206 fast-acting fuse with the highest interrupt rating and lowest internal cold resistance

Image of Littelfuse's 501 Series – High Current 1206 Fast-Acting FuseThe 501 series SlimLine® high current, high temperature very fast-acting lead-free, halogen free, thin-film fuse has been designed specifically to provide over current protection to circuits that see high working ambient temperatures (up to 150ºC). It has the highest interrupt rating (150A @ 24VDC) and the lowest internal cold resistance available in market to date.  The general design ensures excellent temperature stability and performance reliability. In addition to this, the high I²t values typical of the Littelfuse Thin-Film fuse family ensure high inrush current withstand capability.

Features Applications
  • Operating Temperature -55°C to +150°C
  • Designed to Provide Over Current Protection in High Current Voltage Regulator Module (VRM) Applications
  • 100% Lead-Free and RoHS Compliant
  • Suitable for Both Leaded and Lead-Free Reflow / Wave Soldering
  • Voltage Regulator Module (VRM) Equipment
  • DC-DC Converters
