A resettable fuse or polymeric positive temperature coefficient device (PPTC) is a passive electronic component used to protect against overcurrent faults in electronic circuits. It can trip many times, without parameters change. The component is also known as a multifuse or polyfuse or polyswitch.

Features:

• radial leaded devices 
• cured, flame retardant epoxy polymer insulating material meets UL94 V-0 requirements
• agency recognition: UL、CSA、TUV
• lead-free and compliant with the European Union RoHS directive 2002/95/EC
