Thermal sensitive Fuse, SMD 1206, 32 VDC
USN 1206
Temperature sensitive SMD fuse
32 VDC  ·  PCB, SMT
Description
- Temperature sensitive SMD fuse
- Customer-specific pre-arcing time characteristic as a function of ambi-
ent 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 re-
quirements.
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
