Pinout
The SMD100F-2 is a Polymeric Positive Temperature Coefficient (PPTC) resettable fuse. It typically comes in a Surface-Mount Device (SMD) package. This type of component is used to protect electronic circuits from overcurrent conditions.
The SMD100F-2 usually has a 2-pin configuration, as it needs to be connected in series with the circuit it is protecting. The primary function of this component is to allow normal current to pass under typical operating conditions. However, if an overcurrent situation occurs, the device's resistance increases sharply, effectively limiting the current flow and protecting the circuit. Once the overcurrent condition is removed and the device cools down, it will reset itself and allow normal current flow to resume. This resettable characteristic is what differentiates PPTCs from traditional fuses, which need to be replaced once they are blown.
