PTC / PPTC

PTC / PPTC

PTC thermistors are resistors whose temperature coefficient is positive, since their ohmic value depends on the temperature, specifically increasing at the same rate as it. They are used in a wide variety of applications: current limiting, temperature sensors, demagnetisation, and for protection against overheating of equipment such as electric motors.

By comparison, the PPTC are positive polymer coefficient devices, a passive component used in the protection against current peaks in electronic circuits. They are similar in function to PTC thermistors, but operate with mechanical changes instead of charging the effects of the carrier on the semiconductors.

Eurotronix has an extensive portfolio of qualified suppliers and professionals to provide solutions in electronic protections to multiple applications from different sectors.
