0402-035 PTC Resettable Fuse 0.35A Stable Trip Micro Protection Device | RUILON

The 0402 Series Positive Thermal Coefficient (PTC) resettable fuses are ultra-miniature overcurrent protection devices designed for compact electronic circuits requiring reliable and space-saving protection. These components automatically increase resistance during fault conditions such as short circuits or overloads, effectively limiting current and protecting sensitive electronic components.

The 0402 series is optimized for low-profile PCB designs and offers stable trip characteristics, fast response time, and automatic recovery once the fault is cleared. Its extremely small footprint makes it ideal for modern miniaturized electronics.
