Model 1812L075/33DR
Description Littelfuse POLY-FUSE Resettable PTC -1812L Series Littelfuse 1812L Series PTC provides surface mounted overcurrent protection for applications with strict space requirements and the need for resettable protection. ###Surface mount technology (fuse) # # # Surface mount technology * * Resettable fuse * * is used to prevent electrical and electronic circuits from being damaged by excessive current. They can quickly switch from a low impedance state to a very high impedance state under electrical overload or short circuit conditions, and can automatically reset and return to a low impedance state after the fault disappears and the power is cut off. After thousands of cycles of use, it is still a maintenance free automatic reset small model that does not require a fuse holder. It is mainly used for safety system power supply and transformer power switch devices, automotive and medical equipment instruments and control computers and peripheral devices, audio and video, and telecommunications
