Description and Introduction
The 1206L Series PTC provides surface mount overcurrent protection for applications where space is at a premium and resettable protection is desired. The part 1206L012WR is a resettable PTC (Positive Temperature Coefficient) fuse manufactured by LITTELFUSE. It is designed for overcurrent protection in various electronic circuits. The key specifications for this part are:
- **Hold Current (Ihold):** 1.2 A This PTC fuse is resettable, meaning it can return to a low-resistance state after the fault condition is removed, providing reusable overcurrent protection. |
