PTC resettable fuses, also known as polyfuse, polymeric positive temperature coefficient (PPTC) or fuse poly switch, are self-regulating overcurrent protection devices. They are composed of a conductive polymer material that has a high resistance and two metal electrodes. When the current passes through the circuit, the heat generated by the material will increase with the increase of the current, resulting in a rapid increase in resistance until a certain point. When the current exceeds a predetermined limit, the resistance will remain high, thus preventing excessive current from passing through the circuit. PTS181233V075 is a PTC resettable fuse with an inner diameter of 18mm and a height of 12mm (33x75 as measured in milimeters), which provides overcurrent protection with a push-to-reset circuit breaker function. The application field of PTS181233V075 is mainly related to consumer electronics, since it is designed to protect electronic devices from overcurrent which can be caused either by an electrical fault or by external factors such as a short-circuit or a power surge. It can be used in a variety of electrical appliances and devices, including air conditioners, audio equipment, electric vehicles, computer components, power supplies and more. The working principle of PTS181233V075 is based on the dynamic characteristics of the polymer material inside the device. As current passes through the polymer material, the heat generated is dissipated in the form of microcrystals as the temperature of the material increases, causing it to change shape and increase its resistance. When the temperature rises enough to equal the melting point of the polymer material, the resistance increases rapidly. This rapid increase in resistance results in a sudden drop in the current passing through the circuit, thus preventing it from exceeding the predetermined limit. The PTS181233V075 also has a range of added features such as reverse-polarity protection, no external voltage is needed for operation, durability, time-delay functions and automatic reset after current interruption, making it an ideal choice for various consumer electronics applications. Its compact size also makes it a great choice for low-profile applications. In conclusion, the PTS181233V075 PTC resettable fuse is a versatile and reliable component that has a multitude of applications in the consumer electronics industry. It has a unique working principle, which is based on the dynamic characteristics of the polymer material inside the device and the increased resistance caused by temperature rise. Its features also make it an ideal choice for applications of various sizes, from high-powered devices to low-profile ones.
