The JK-SMD0603-020 with PTC Resettable Fuses 0603 RoHS manufactured by Jinrui Electronic Materials is a surface mount device (SMD) designed to protect circuits, components, and systems from electrical faults and overloads. The 0603 RoHS component consists of a polymeric positive temperature coefficient (PTC) element connected in series with a fuse element. The fuse element is rated for 0.2A and will melt at a pre-defined current to create an open circuit. The PTC element in series with the fuse element will act as a self-resetting fuse and will return to its normal character upon the removal of the fault. The compact size of the 0603 RoHS component enables easy PCB layout and installation into many applications. The component is RoHS 2 lead compliant, making it an environmentally friendly alternative to other protection components. The JK-SMD0603-020 with PTC Resettable Fuses 0603 RoHS manufactured by Jinrui Electronic Materials is designed for use in a wide variety of electrical and electronic systems, such as computer motherboards, consumer electronics, automotive electronics, and more.
