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:

• End stackable for standard 0.1" integrated circuit pitch.
• Molded 0.3" integrated circuit packing outline allowing automatic insertion.
• Smaller size makes better heat convection during PC board reflow wave soldering.
• Top tape sealed to withstand wave soldering, board washing.
• All plastics are UL 94V-0 grade fire retardant.
• Twin contacts designed to ensure stable contact.
• Gold plated contact to ensure low contact resistance and Tin plated terminals to prevent contamination during soldering. 
• RoHS Compliant

Applications:

• Numerical setting for computer terminal equipment
• Price setting for vending machines
• Programming for game machines
• Programming for industrial equipment and measuring instruments 

Specifications:

• contact rating: 
  • switching: 25mA, 24VDC
