The PROSEMI SMD PPTC (Polymer Positive Temperature Coefficient) fuse provides reliable overcurrent protection in a compact surface-mount design, making it ideal for space-constrained applications. PROSEMI PPTC devices which offer a resettable overcurrent protection solutions, thereby reducing warranty service and repair costs.
Ideal for situations where frequent over-current conditions occur or constant uptime is required. PPTC Fuses are typically used in consumer electronics, telecom, automotive and medical equipment protection applications. Its fast response time and low resistance ensure efficient performance, while its surface-mount form factor makes it easy to integrate into modern, high-density circuit boards.
With a variety of current ratings and sizes available, the PROSEMI SMD PPTC fuse offers an effective, cost-efficient solution for protecting your circuits while maintaining long-term reliability.
SMD Resettable Fuses, also known as PTC (Positive Temperature Coefficient) fuses, are polymer-based circuit protection devices that automatically reset after a fault condition is cleared. Unlike traditional one-time fuses, they return to their normal conductive state once the overcurrent or overtemperature event subsides, eliminating the need for replacement and reducing maintenance costs.
