High Reliability Ceramic PTC Thermistor Long Service Life Quick Reaction Time

The thermistor has the characteristics of high sensitivity, wide operating temperature range, small size, convenient use, easy processing into complex shapes, good stability, and strong overload capacity. In terms of application, it can not only be used as a measuring element to measure temperature, but also can be used as a control element to control The level of temperature and circuit compensation components are widely used, such as curling irons, household appliances, etc., all have thermistors.

PTC thermistor manufacturing process

The mixture (barium carbonate, titanium dioxide and other materials) that can meet the requirements of electrical and thermal properties is weighed, mixed and then wet-ground, dehydrated and dried, and then dry-pressed into discs, rectangles, rings, and honeycombs. rough. These pressed blanks are sintered into ceramics at a relatively high temperature (about 1400°C), and then electrodes are applied to metallize the surface, and the resistance value is graded and detected. The package is brazed or assembled according to the finished structure, followed by a final comprehensive inspection.

The characteristics of PTC thermistor are:

1. Power saving
The energy input of the thermistor adopts the proportional type, which has the current limiting characteristic of the protection circuit, and saves power compared with the switching energy input of heating elements such as nickel-chromium wires.
2. Long service life
The PTC thermistor itself is an oxide, there is no high-temperature oxidation defect of the nickel-chromium element wire, and there is no fragile situation of the infrared diode, the service life is long, and the service life of the porous type is longer than that of the non-porous type
3. It has the special performance of constant temperature, adjustment and temperature control
When AC or DC voltage is given to the thermistor element to heat up, below the Curie temperature, the resistivity is relatively low; if it is higher than the Curie temperature, the resistivity suddenly increases, so that the thermistor current is reduced to a fixed value, reaching Automatic constant temperature, temperature adjustment purpose
4. Non-combustible, safe and stable
When the PTC thermistor is hot, it does not glow red, has no flame, and is difficult to ignite
When the temperature near the thermistor exceeds the limit value, its power is automatically reduced to a stable value, and no burning accidents will occur
5. Wide operating voltage range
PTC thermistor can be used normally under low voltage 6 to 36V and high voltage 110-240V
6. Simple structure
The thermistor itself is to be automatically temperature controlled, and no other automatic temperature control circuit assembly is required
