Introduction
PTC stands for positive temperature coefficient. PTC thermistors
are resistors with a positive temperature coefficient, which is
thermally sensitive resistor whose resistance increases
significantly with temperature. PTC could keep working properly
under low voltage range between ***5 voltages and high voltage
range from ******0 voltages.
Construction and
properties of PTC pellet
Ceramic materials are usually good for high resistance insulation,
and ceramic PTC thermometers are often fabricated using mixtures of
barium carbonate and some other poly-crystalline ceramic materials.
It has a lower resistance and semi conducting properties. The
materials are ground, mixed, compressed into disks or rectangle
shapes and sintered, preferably at temperatures below ***0 °C.
Afterwards, they are carefully contacted, provided with connection
elements and finally coated or encased.
