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:

• 0603 dimension, surface mount, solid state
• Faster time to trip than standard SMD devices
• Lower resistance than standard SMD devices
• Operation current: 50mA~200mA
• Maximum voltage: 9V~60Vdc
• 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
