PTC Resettable Fuses

(Showing 2 of 50)

A PTC resettable fuse  is a passive electronic component used to protect against overcurrent and/or overtemperature faults in electronic circuits. The device is also known as a multifuse or polyfuse or polyswitch. They are similar in function to PTC thermistors in certain situations but operate on mechanical changes instead of charge carrier effects in semiconductors. If you can't find what you are looking for or have large volume requirement, please don't hesitate to contact us.

Why Choose PTC Resettable Fuses?

PTC resettable fuses are ideal for applications where traditional fuses might not be practical. Instead of blowing out during a fault, PTC fuses automatically reset after the fault is cleared, making them reusable and cost-effective. These fuses work by increasing their resistance as they heat up due to overcurrent, thus limiting the current flow and protecting the circuit. Once the fault condition is removed and the fuse cools down, it returns to its low-resistance state, allowing normal operation to resume.

Key advantages of using PTC resettable fuses include:

  • Reusability: Unlike traditional fuses, PTC fuses reset themselves after the fault condition is cleared.
  • Compact Design: Available in SMD and radial formats, these fuses are perfect for applications where space is limited.
  • Wide Range of Voltage and Current Ratings: Suitable for a variety of low- and high-voltage applications.
  • Cost-Efficiency: No need for replacement after each fault, making them a long-term solution for circuit protection.
  • Fast Reaction to Faults: Protects against overcurrent conditions quickly to prevent damage to sensitive components.
