What leads Thermistors to failure mode (short circuit mode and open-circuit mode)?
The reason why substrate burn-down and blow off occurred while turning on devices, subjected to low temperature of sintering, ceramic isn’t firing mature, as well as mechanical stressed, causing larger current than the ripple current can tolerate, etc …

Solutions:
1) Sintering at the right temperature.
2) Reduce defects
3) Avoid large current
4) Only use high purity, and good raw materials

The demand for Negative Temperature Coefficient Thermistor has been increased these years in automotive industry, for the use of powertrain, safety and controls, as well as in alternative of fuel vehicles, since the awareness of eco-friendly has arouse.

Thermistors are growing steady in the market at the moment.
And also, the research has shown that this trend will keep following up in the upcoming years.

Thermistors are available in a range of types, materials and sizes according to the response time and operating temperature. Also, hermetically sealed thermistors eliminate errors in resistance readings due to moisture penetration while offering high operating temperatures and a compact size.

The three most common types are: Bead thermistors, Disk and Chip thermistors, and Glass encapsulated thermistors. NTC disc and chip thermistors are a cost effective and simple option for solving temperature measurement or temperature compensation challenges. NKT NTC thermistors, surface made by phenolic-resin (black) or silicone (green) materials, belong to disk and chip thermistors.

The NKT NTC thermistors have metallized surface contacts. Because of larger size, they have a higher dissipation constant (power required to raise their temperature by 1°C) and since power dissipated by the thermistor is proportional to the square of the current, they can handle higher currents much better than other type thermistors.
Disk type thermistors are made by pressing a blend of oxide powders into a round die, which are then sintered at high temperatures. Chips are usually fabricated by a tape-casting process where slurry of material is spread out as a thick film, dried and cut into shape.

A wide range of applications coupled with low costs and high accuracy make NKT NTC thermistors a frequently used device. The applications performed by these devices allows for thermistors to function as accurately as they do. NKT NTC Thermistors are used in a wide range of different industries that require high accuracy when it comes to temperature. Some of the applications include:

Temperature compensation: considering that temperatures fluctuate as a result of their environment, NTC thermistors are able to compensate for changes to keep temperature where it needs to be. Examples of circuits that might require compensation are, LCD displays, charging batteries, oscillators, HVAC( Heating, Ventilation and Air Conditioning) and refrigeration equipment

Inrush current limiting: not only is a NTC thermistor subject to a change in temperature, but it is also susceptible to changes in power. When there are changes in power, a NTC thermistor experiences a time lag prior reaching lower resistance. The time lag is utilized to help limit the inrush surge currents. It used for medical industry including catheters, dialysis equipment, and patient monitoring.

Temperature measurement: If low cost, longevity, and accuracy are important qualities, a NTC thermistor is the best option. For the operating of dryers, coffee devices. Automotive and aerospace industries use NKT NTC thermistors for test and measurement as well as production applications

Fluid level gauging: A thermistor will be able to sense an absence or presence of a liquid. It is able to do this through measuring the difference between dissipation constants (between a gas and a liquid).

NTC stands for “Negative Temperature Coefficient”. NKT NTC thermistors are resistors with a negative temperature coefficient, which means that the resistance decreases with increasing temperature. An NTC is commonly used as a temperature sensor, or in series with a circuit as an inrush current limiter. NKT NTC sensors are typically used in a range from −40°C to +200°C.

Kingtronics’s NKT Negative Temperature Coefficient (NTC) thermistors are available in an array of designs to fit nearly any desired application. We created using the best high purity materials for reliable results you can count on and customizable to fully meet your needs.
