PTS18128V200 Circuit Protection

PTC resettable fuses are popularly used in a variety of applications due to its versatile features. The PTC Resettable Fuse, PTS18128V200 is a polymeric negative temperature coefficient (PNTC) device developed by a Chinese manufacturer for high reliability applications. This device uses a thin-film conducting element with a stable coil design. The PTC Resettable Fuse embodies a zero voltage photo-triac (ZVPT) to detect an overcurrent caused by an overload or a brief short circuit within an electronic circuit.

The PTC Resettable Fuse, PTS18128V200 is designed for application in power supplies, communications equipment, medical equipment, and consumer electronics. It is used in many electronic circuits to protect against current overloads. The PTC Resettable Fuse is a one-time device that can be reset after it trips, unlike the traditional fuse, which can be replaced. This resettable fuse features a fast response time and a low additional voltage drop across the electrical device.

The working principle of the PTS18128V200 PTC Resettable Fuse is based on the thermodynamics of semiconductor materials. It consists of a metal-oxide-semiconductor (MOS) dielectric material, a thin-film conductor, and a ZVPT. As the current in the circuit increases, the temperature of the fuse rises, due to the electrical power consumption in the device. The thin-film conductor provides a temperature slope to the fuse, allowing for the generation of heat when the current exceeds its rated value. The ZVPT is triggered when the temperature of the fuse reaches its rated value, and the current is shut off. Once the current is shut off, the fuse is reset and the device remains off until the cause of the overload is rectified.

The PTC Resettable Fuse, PTS18128V200 is a reliable, cost-effective device. It provides efficient overcurrent protection, fast response times, low additional voltage drops, and low-cost manufacturing. It is designed to be used with a broad range of current ranges from 5A to 20A, and can withstand temperatures up to 85°C. It is RoHS compliant and UL/CSA certified. The PTS18128V200 PTC Resettable Fuse is an ideal choice for protecting sensitive electronic components from current overloads caused by momentary faults.
