For customer’s convenience, we provide assembled heating elements:
PTC heating element with insulator and wire, PTC heating element
with shell, PTC air heater, PTC for hair straightener, PTC for
curler, PTC with resin coating, PTC for water heater, refering to
2. Some samples of uses.
Dryer, air heater, air condition heater, mosquito killer, car's
heater, humidifier, de-humidifier, heating-plate, massager,
physical therapy machine, hot glue-gun, hair crimper, hair
straightener, coffee /milk warmer, water boiler, and so on. PTC is
very suitable as a heating element, if the surface temperature on
end product was under 260°C.
3. Notice in appliance.
1) The surface temperature of PTC can be controlled by itself,
control circuit and protecting circuit may be omitted in most
2) It can be used for heating liquid, and it’s no problem when
liquid was dried.
3) It can be used for heating air with fan blowing, and it’s no
problem when the fan did not operate..
4) There are four electrodes coating to be selected:
neckel+silver,melt-jet aluminum, screen print aluminum, screen
5) Very long life, 10 years or longer is possible.
6) Very high reliable, over temperature was impossible.
7) The surface temperature increases (or decreases) about 8°C, when
supplied voltage increases (or decreases) 2 time. -
8) If customer need the PTC with wire, insulator, or shell. please
select other types manufactured by our company.
9) Parallel connection is necessary for two or more PTC connection.
10) The steady state power may be very different with different
applied condition for same PTC. The faster is the heat conduction,
the higher is the steady state power.
11) In most situation, the type of electric contacts on large sides
was suitable; only in some very special situation, the type of
electric contacts on one side, and the type used for SMT. was used.
