USN 1206 Temperature sensitive SMD fuse en IM0016958
Temperature sensitive SMD fuse

Series: USN 1206

Thermal sensitive Fuse, SMD 1206, 32 VDC

New_Logo Free Sample Request

Description

  • Temperature sensitive SMD fuse
  • Customer-specific pre-arcing time characteristic as a function of ambient temperature
  • Ensures the complete time-current curve from 0 A to BC
  • Impermeable to potting compound used to achieve hermetic seal for use in intrinsically safe applications according to ATEx and IECEx requirements.

Unique Selling Proposition

  • Combines a Standard Fuse characteristic with an additional ambient temperature sensitivity
  • Ceramic glase fiber inforced material
  • Excellent inrush current withstand capability
  • High melting I²t-values

Applications

  • Secondary Protection DC and AC
  • Automotive electronics
  • Intrinsically safe electronics
  • Battery protection
  • In all electronics with temperature-critical components (eg Mosfet's)
