The SMD1210B020TF with Resettable Fuses - PPTC PPTC 30V 0.2A, manufactured by Yageo, is a surface mount over-current protection device designed to protect against over-current or short-circuit faults. It features two-terminal zero ohm resistor technology and is designed to regulate currents from 0.2 amperes to 30 volts. The PPTC technology allows the device to self-reset once the fault current is removed, allowing it to be quickly brought back to a normal operating state. This device is ideal for use in automotive, electronics, consumer, medical equipment, and telecommunications applications.
