Posistors, PTC


For reliable operation of electronic devices and their protection against current surges and overvoltage, you must use fuses. PTC-thermistors tend to sharply raise the resistance to stabilize the temperature. Posistors are used in household appliances, industrial equipment, telecommunication lines and in automotive electronics. In working and homeFor reliable and long-lasting electronics, reliable temperature control should be performed. Thermistors guarantee protection of devices against unstable current loads and stabilize the temperature resistance in adverse climatic conditions. Posistor (PTC) is a semiconductor element with a positive temperature coefficient, which increases as the temperature of the resistor increases. When a high voltage is applied to the device, the electronic elements heat up, therefore the PTC-thermistor plays the role of: heater and temperature sensor. The principle of operation of the PTC-thermistor is based on the reduction of the range of movement of the charge of electric current with increasing temperature in the device. Pozistory divided into two main groups: silistors are heat-sensitive semiconductor elements, which are distinguished by the fact that they are positive (temperatures up to 150 ° C) and negative (temperatures above 150 ° C). They control the temperature in the device. “Protective thermistors” are built-in semiconductor elements that are designed to protect the temperature in the device from current and voltage surges. Thermistors of the RTS type are divided into such types depending on climatic indicators: low temperature – temperature up to 170K; medium temperature – 170-510K; high temperature – 570-1300K. If necessary, our professional managers will always help you choose and buy posistors. Product only from time-tested manufacturers. Delivery of products from Asia, Europe and America. Where is posistor used? lighting systems, silistrams are used to protect against overloads in the electrical network. In the online store of the company Eurocom Components the price of the posistor for temperature depends on its type and purpose. You can order goods from a trusted manufacturer both in retail (from one) and wholesale (small or large). Delivery throughout Ukraine.
