The SMD 1210 series resettable fuse uses a standard 1210 surface mount package to provide strong overcurrent protection for 6V to 60V DC applications.
The device uses the inherent characteristics of PTC (positive temperature coefficient) materials.When an overcurrent fault occurs, the resistance will increase nonlinearly, thereby effectively throttling the current; after the fault is eliminated, it can automatically restore low-resistance conduction without intervention.
The wide operating voltage range, intelligent self-healing function and excellent performance stability make the SMD 1210 series extremely valuable in power management, industrial control systems, automotive electronics, LED lighting drivers and communication equipment. It is designed to minimize maintenance costs while building a solid line of defense for the reliable operation and safety of terminal products.
