PTC resettable fuses are an important component in electronic industry, and AGRF1200 is one type of them. This fuse is designed to monitor and protect low voltage DC applications, especially those related to communication such as advertising, audio readouts, vehicle starts and other applications involving 12 Volts or less.

The AGRF1200 resettable fuse contains Polymeric Positive Temperature Coefficient (PPTCs) with an integrated overcurrent detection circuit. AGRF1200 applications include protection of power supply lines, telecom and network equipment, solenoid valves, SMPS/charging systems, industrial ASICs/ICs, field bus networks, LED Lighting, consumer electronics, and robotic/automation.

The working principle of AGRF1200 is based on the PPTC element being embedded inside the stand-off housing. When the current reaches over the threshold, the PPTC element switches on. This triggers a thermal event which causes an increase in device temperature. Once the thermally set threshold is reached, the fuse will constantly draw current, dissipating it internally as heat, thus limiting the overload current and protecting the device.

The AGRF1200 fuse also supports the instantaneous off-state current to prevent inrush current from damaging the power supply. The unique design offers a wide adjustment range of trip characteristics, which enables system operators to customize the device protection according to their specific needs.

AGRF1200 resettable fuse has a wide range of features to meet customers’ requirements. It is an experience, reliable, and cost-effective solution for protecting a variety of electronic systems from damage due to overcurrent. Its UL certification ensures that it fulfills the relevant UL safety and performance requirements, providing operators with the confidence that their equipment and applications will remain safe and reliable.
