Description

This is PTC thermistor for overcurrent protection . ( PTC-C955-E8, PTC C965-1E2, C995-13E ).

A PTC thermistor, short for Positive Temperature Coefficient thermistor, is a type of temperature-sensitive resistor with a characteristic that exhibits an increase in resistance as its temperature rises. PTC thermistors are widely used in various electronic applications for temperature sensing, current limiting, and overcurrent protection.

PTC thermistors are often employed as resettable fuses or self-resetting fuses. In circuits with a current surge or overcurrent conditions, the PTC thermistor heats up due to the increased current flow. As the temperature rises, its resistance increases dramatically, limiting the current flow and providing protection to the circuit and components.

EPCOS PTC Thermistors are thermally sensitive semiconductor resistors made of ceramic components whose electrical resistance rapidly increases when a certain temperature is exceeded. This feature makes EPCOS PTC Thermistors ideal for use in electrical and electronic engineering applications, for example as resettable fuses against current overload or as short circuit protection in motors. Applications include measurement and control engineering, entertainment, household, and automotive electronics, and data systems and telecommunications.
