Resettable Fuses PTC 6V 1.25A WT-1206-125 SMD
The Resettable Fuses PTC 6V 1.25A WT-1206-125 SMD is a surface mount resettable fuse designed to provide overcurrent protection for electronic circuits. With a holding current of 1.25A and a trip current of 2.50A, this fuse offers reliable protection in situations where an overload or short-circuit could potentially damage sensitive components. The fuse will automatically reset after the fault condition has been cleared, making it ideal for applications that require continuous protection without the need for manual intervention.
Features:
- Compact design saves board space.
- RoHS compliant and lead-free.
- Halogen-free, environmentally friendly.
- Fast response to fault current.
- Symmetrical design for consistent performance.
