Littelfuse Polyfuse PTC Radial Resettable Fuse - 30V 9A

The Littelfuse Polyfuse PTC Radial Resettable Fuse provides reliable overcurrent protection for a wide range of electronic circuits. Designed using advanced positive temperature coefficient (PTC) technology, this component acts as a self-resetting safety device. When an overcurrent condition occurs, the Polyfuse heats up and increases its resistance, effectively limiting the current flow and protecting sensitive components from damage. Once the fault is cleared and the power is removed, the device cools down and returns to its low-resistance state, allowing the circuit to function normally again without the need for manual replacement.

Featuring a radial leaded design with through-hole mounting, these resettable fuses are highly suitable for automated printed circuit board (PCB) assembly and wave soldering processes. The rectangular fuse shape and specified lead spacing ensure secure and stable placement on the board, offering consistent performance. Engineered for durability, the POLY-FUSE 30R series operates efficiently across a broad temperature range, making it suitable for demanding environments. Whether you are designing consumer electronics, industrial controls, or power management systems, the Littelfuse Polyfuse provides a robust and maintenance-free solution for circuit safeguarding, reducing downtime and overall service costs.
