Single-end glass sealed NTC thermistor temperature sensor products are widely used in temperature sensing of laser diodes, optical components, industrial process control, etc. These applications require higher temperature sensitivity, long-term stability, and higher application temperatures.

In order to meet your different needs, this series of products are divided into multiple models:

ATH100K1R25: the lead is copper-plated bare wire;

ATH100K1R25T70: The lead sleeve has a Teflon sleeve;

ATH100K1R25T70S: The lead wire is not only covered with a Teflon sleeve, but the epoxy head is sealed between the temperature sensor and the sleeve.

MF 51 103 F 3950
① ② ③ ④ ⑤
①MF ¬-- negative temperature coefficient (NTC) thermistor code.
②5D-- single-ended glass encapsulated NTC thermistors.
③103 - thermistor nominal resistance, indicating that the nominal resistance of the resistance: 10 × 103 (Ω).
④F-- resistance value error (accuracy) is: F = ± 1%, G = ± 2%, H = ± 3%, J = ± 5%
⑤3950-- thermal resistance index (material factor) B is: 395 × 10 (K)
 Note: according to customer requirements, provide different resistance, B value precision and customization.
 When measuring NTC thermistor, we must note the following:
• can not be measured in the air, the larger the difference in air temperature measurement inaccurate, resulting accuracy deviation.
• The use of high-precision thermostat bath was measured after the test NTC, in the bath, the bath temperature must be stabilized before measurement.
• Measure the voltage as low as possible to reduce measurement errors caused by self-heating of the NTC.
• High temperature measurement, the thermometer on the required temperature of the bath is corrected, check
