RL16-400 16V 4A PPTC Resettable Fuse | Heavy Load Circuit Protection | RUILON

The RUILON RL16 Series Positive Thermal Coefficient (PTC) resettable fuses are high-reliability overcurrent protection devices designed for medium to high power electronic circuits. These components automatically increase resistance under fault conditions such as short circuits or overloads, effectively limiting current flow and protecting sensitive electronic systems from damage.

The RL16 series offers a wide current range, stable trip performance, and fast response time, making it suitable for demanding applications where higher current handling and robust protection are required. Its radial leaded package provides excellent mechanical strength and easy PCB mounting, ensuring dependable performance in industrial and power electronic designs.
