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:

• 1206 Dimension, surface mount, solid state 
• Faster time to trip than standard SMD devices 
• Lower resistance than standard SMD devices 
• Operation current: 0.25A~2.0A 
• Maximum voltage: 6Vdc 
• Temperature range: -40 to 85 ℃ ℃
• Tape and reel available on most models 

Applications:

• Almost anywhere there High-density boards is a low voltage power supply and a load 
• to be protected including: 
• Computers & peripherals 
• General electronics 
• Automotive applications
