The RL16-1400 with PTC Resettable Fuses Through Hole RoHS is a surface mount automated resetting fuses manufactured by Ruilongyuan. This part is designed to protect circuits against transient overvoltage and current overloads. It is able to operate up to 16A at 1000V and shown to have high stability, strong interface, resistance to vibration, and low temperature coercivity. The fuse is composed of a piezoresitive element, a glass capsule, and a zeolite dust plug. The PTC fuse has a temperature sensitive element that can trigger an electrical reset that helps to protect the circuit by automatically opening the fuse if it is overloaded. The fuse has two terminals, one labelled "F" and the other labelled "C", which together carry the current from the device to the fuse element. Additionally, the part is Lead-free RoHS compliant, making it environmentally friendly and safe to use.
