Resettable Fuses PTC 16V 250mA WT-1206-025 SMD
The WT1206-025 is a surface-mount PPTC resettable fuse engineered to protect electronic circuits from overcurrent events. It features a hold current of 250mA, meaning it can carry up to 250mA without tripping, and a trip current of 500mA, at which it transitions to a high-resistance state to limit current flow. The device supports a maximum voltage of 16VDC and can interrupt fault currents up to 100A, making it suitable for low-power applications requiring reliable protection.
Features:
- Compact 1206 package saves board space.
- RoHS compliant and lead-free.
- Halogen-free.
- Fast response to fault currents.
- Symmetrical design for easy integration.
