The SMD2920 resettable fuse patch series produced by Ruilongyuan Electronics is an over-current protection device, which is processed by a special process by using high-character organic polymer under high pressure and high temperature conditions, doped with conductive particles. It has an automatic recovery function: it presents a high-resistance state when over-current occurs, and can return to normal from a high-resistance state after the over-current subsides. Package: 2920, can withstand surge energy of 0.3～7.0A.
