NTC Thermistor, also called Negative Temperature Coefficient Thermal Resistor, whose resistance varies by temperature change and which are one of the most commonly used devices for the measurement of temperature. Thermistors are majorly made up of metal oxides - manganese, cobalt, copper and nickel. While temperature rises, the charge density and moving rate of metal oxides increases and makes conductivity increases; resistance decreases, for that thermistors respond negatively to the temperature. Their resistance decreases with the increase in temperature, also each specific thermistor has its own unique resistance vs. temperature characteristic.
Product Parameter (Specification)
Thermistors are resistive devices made up of metal oxides 鈥?manganese, cobalt, copper and nickel. They can be formed into a bead, disc, chips, films, or probes, and encapsulated in epoxy or glass. NTC Thermistors are available in a wide variety of configurations and protective coatings to suit almost any application.
Product Feature And Application
* NTC Thermistors are used in automotive applications. i.e: coolant temperature and /or engine oil temperature monitoring for feedback to the engine control unit and to the dashboard.
* NTC Thermistors can be used in medical application, especially suited for continuously monitoring a patient's body temperature, or can be used to monitor the temperature of an incubator.
* NTC Thermistors are used in intelligent home appliances for temperature sensing, such as air- conditioner, refrigerator, microwave oven, coffee machine, oven, washlet, indoor temperature controller, ...etc.
* NTC Thermistors are also commonly used to monitor the temperature of battery packs while charging, kitchen appliances, instrumentation, air-gas, etc.
* NTC Thermistors can be used as inrush-current limiting devices in power supply. They prevent high peak currents from flowing into a device during power-on, but will allow normal current flow to resume after power-on.
* NTC Thermistors can be used as liquid level detection and liquid flow measurement.

8. Special Requirement
Resistance Value
NTC thermistors are typically specified or referenced with a resistance value at 25 掳C. However, it is equally important to consider the minimum and maximum resistance values at the extremes of the operating temperature range.
Resistance Temperature Characteristics
Thermistors may be specified with either a temperature tolerance or a resistance tolerance at either a single temperature point or over a temperature range
Configuration
NTC thermistors come in several forms: bare discs, bare chips, glass coated beads, radial leads, thin film, surface mount, etc. The leaded styles are available with different housings, lead lengths, and encapsulation.
Mounting
Depending on application, mounting methods vary from screw mounts, pipe straps, tape or glued in. Please contact our sales representative for more information.
Special Requirement
Should special requirement such as space limitation, harsh environment, response time be considered, please be sure to let our sales representative know.
