Low-R0 SMD Polymer PPTC Fuse

The PROSEMI Low-R0 SMD Polymer PPTC Fuse offers advanced overcurrent protection with an ultra-low resistance design, making it ideal for high-performance, space-constrained applications. Engineered with a polymer-based Positive Temperature Coefficient (PPTC) material, this fuse provides self-resetting protection against short circuits and overloads, automatically returning to normal operation once the fault condition is cleared.

With its low resistance (Low-R0) feature, it minimizes power loss and ensures efficient current flow, making it perfect for sensitive electronics, consumer devices, automotive circuits, mobile devices, and power management systems. The compact SMD form factor ensures easy integration into modern, high-density circuit boards, while providing reliable, long-lasting protection without the need for replacement.

The PROSEMI Low-R0 SMD Polymer PPTC Fuse delivers fast response times and high reliability, offering an effective, cost-efficient solution for protecting circuits in demanding applications.
