The nSMD025-30V with PTC Resettable Fuses 1206 RoHS is a surface mount device (SMD) manufactured by TECHFUSE that features a PTC (positive temperature coefficient) resettable fuse in a 1206 form factor and is designed to be used in a 30V DC application. It is compliant with RoHS (Restriction of Hazardous Substances) regulations. The PTC fuse is designed to detect and cut off the electric current when overheating or overloading is detected, a feature which reduces the risk of electrical faults and makes it a more reliable and safer component than a conventional fuse. The PTC fuse is resettable after the fault has been cleared, meaning it does not have to be replaced after every overcurrent event. It can cover a wide range of applications, making it suitable for use in consumer electronics, automotive, and industrial applications.
