PTC resettable fuses, also known as polyfuses, are electric components which protect electronic devices from overload. They are widely used in many electrical and electronic products such as appliances, computers, and automotive accessories. The LTP180 PTC resettable fuse is a popular, reliable, and cost-efficient solution for protecting electronic devices from overcurrent and voltage transients.

The LTP180 is a polymeric, positive temperature coefficient (PPTC), fused switch made up of a semiconductor material and a conductive metal plate. It is installed between an AC or DC power source and the device being protected. The device is designed to limit the current flow to a maximum rating of 180 Amps. This rating is based on the preset temperature-related trip point. In the event that the electrical device draws more current than the trip point, the PTC element will reach its elevated temperature and expand, breaking the electrical circuit. The LTP180 is designed to be reset automatically after the electrical overload has been removed, restoring power to the device.

The LTP180 is a small yet rugged device that has been tested to meet UL, CSA, and CE safety standards. The device is available in a variety of configurations such as blade, radial, and snap-in designs. Additionally, the LTP180 offers a wide operating temperature range and can be tested to meet various international standards. It is designed to maintain reliable performance in harsh environments and is capable of withstanding electrical surges up to 600V.

In the event of an electrical overcurrent, the LTP180\'s semiconductor material begins to heat up, causing the element to expand and break the circuit connection. This action occurs almost instantly and prohibits any further current from passing through the component. When the temperature drops, the element contracts and power is restored to the protected device. This process allows for the device to be reset and reused multiple times.

The LTP180 has a wide range of applications, including computers, lights, power supplies, control systems, and automotive accessories. It can be used to protect sensitive loads and circuits from short circuits, overcurrent conditions, and voltage spikes. It is an effective, reliable, and cost-efficient solution for protecting electronic devices from overcurrent and voltage transients.
