PTC heating elements are electric heating elements made of positive
temperature coefficient (PTC) ceramic material. Their core features
include automatic temperature regulation and over-temperature
protection: At low temperatures, their resistance is low, allowing
them to rapidly heat up upon power application. When the
temperature reaches a specific critical point (the Curie
temperature), their resistance increases dramatically,
automatically reducing power consumption to avoid overheating. This
adaptive feature ensures high safety and energy savings, enabling
stable temperature control without the need for additional
temperature control devices.
They are widely used in home appliances (such as air conditioning
auxiliary heating and heaters), automotive electronics (seat
heating and battery preheating), medical equipment, and industrial
applications. Their compact design, long lifespan, and lack of open
flames make them key components in modern intelligent thermal
management solutions.

Features
Safety Protection
PTC heating elements do not glow red or produce open flames during
operation (common resistance wires glow red and produce open
flames), making them non-flammable. When the ambient temperature of
the PTC element exceeds the limit, its power automatically
decreases to a stable value, eliminating the risk of burns.
Stable Performance
PTC heaters feature automatic constant temperature control. No
temperature control system is required; simply power the PTC
directly. When used to heat liquids, such as water, the PTC heater
will not be damaged if the liquid boils dry. Reliable operation
utilizes the PTC's internal temperature control characteristics to
prevent overheating.
Wide Range of Applications
Low-voltage PTC components are suitable for various low-voltage
heaters, instrument low-temperature compensation, heaters in
automotive and computer peripherals, thermal beauty devices, PCB
heating USB heaters, incense burners, mosquito repellents, and
more. High-voltage PTC components are suitable for heating the
following electrical equipment: air conditioners, fan heaters, rice
cookers, hair curlers, electric mosquito repellents, humidifiers,
copiers, hand warmers, shoe dryers, water pipe heaters, travel
clothes dryers, automotive paint booth massagers, electric dining
tables, bottle thermostats, electric kettles, electric blankets,
and more.
