10K 3435 Thin Film NTC Thermistor Sensor Assembly With Extension Cable UL1571 28AWG And Connector 1.25-2Y

Description Of The NTC Thermistor Sensor Assembly

10K 3435 Thin Film NTC Thermistor Sensor Assembly, made of high accuracy sensing element thin film ntc thermistor in 25mm (Available length 10mm~100mm), UL1571 cable and connector 1.25-2Y,designed for narrow application and contact measurement such as car water cup,computer ,printer etc,It is especially suitable for temperature detection circuits for various applications such as current control of HDDs, temperature compensation circuits of optical heads for CD/DVD, temperature monitoring of LED lighting, and temperature control of battery packs.

Features Of The NTC Thermistor Sensor Assembly

* Insulated polyimide film esnure quick response and high accuracy

* High steady and high reliability

* Small zone required

* Good mechanical properties

* Corrosion resistance

* In addition to conventional parameters, our company has also developed thin-film NTC thermistors with sizes of 11mm/15mm/20mm/25mm/28.8mm/26.8mm/36mm/44mm/45mm/50mm/75MM. The above special sizes fill the domestic gap and become my country's lithium battery protection center. Critical thermal element for temperature measurement and temperature protection.

Dimension Of The NTC Thermistor Sensor Assembly

*The B value is calculated using the zero-power resistance values measured at 25 ℃ and 85℃.

Insulation resistance Of The NTC Thermistor Sensor Assembly

Insulation resistance shall be more than 100 MΩ which is measured at DC 100V between film area and terminals.

Climatic test Of The NTC Thermistor Sensor Assembly

1) Dry Heat
After the test samples are exposed in air at 90±1℃ for 1,000 hours, the change ratio of the rated zero-power resistance shall be within ±1% of the initial value.

2) Damp heat
After the test samples are exposed in the humidity of 95% at 40±2℃ for 1,000 hours, the change ratio of the rated zero-power resistance shall be within ±1% of the initial value.
3) Cold
After the test samples are exposed in air at –30±1℃ for 1,000 hours, the change ratio of the rated zero-power resistance shall be within ±1% of the initial value.
4) Loading
After DC 1mA current is applied to the test samples in the temperature of 40±2℃ and the humidity of 95% for 1,000 hours, the change ratio of the rated zero-power resistance shall be within ±1% of the initial value.
5) Change of temperature
One cycle of temperature change shall be carried out under the following conditions.
