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, lower hold current, solid state
• Operation current: 50mA~3.75A
• Maximum Voltage: 60V
• Temperature range: -40 to 85 ℃ 
• Cured, flame retardant epoxy polymer insulating material meets UL 94V-0 requirement
• Bulk packaging, tape and reel available on most models

Applications:

• Ideal for low voltage power supply with a load to be protected:
• Computers & peripherals
• Security and fire alarm system
• General electronics
• Loud speakers
• Automotive applications
• Power transformers
