The ATH10K1R0 series thermistor is a glass package with two coated wires. The glass seal can ensure long-term stability of the product, and the coated wires can prevent short circuits due to their contact with each other. Compared with traditional thermistor-encapsulated thermistors, ATH10KR0 is characterized by smaller size, shorter response time, better long-term stability, and a wider temperature range. ATH10K1R0 is hermetically sealed between the temperature sensing head and the wire. It can work in high temperature liquids up to 250 ° C. 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.

Features:
The size of the temperature sensing part is compact: φ1.0mm * 1.4mm;
Nominal resistance @ 25 ℃: 10K;
Lead length: 66.5 ± 3mm;
High stability: <0.1 ℃ / Y;
High resistance accuracy: ± 1%;
Short response time: 4s (in still air);
Extensive temperature test range: -55 ℃ ~ 250 ℃;
Single-end glass seal can be used in harsh environments such as high temperature and high humidity;
Good stability and high reliability;

①MF ¬ - negative temperature coefficient (NTC) thermistor code.
② 5D - single-ended glass packaging NTC thermistor.
③103 - thermistor nominal resistance, said the resistance of the nominal resistance: 10 × 103 (Ω).
F = ± 1%, G = ± 2%, H = ± 3%, J = ± 5% of the resistance value (accuracy)
⑤ 3950 - resistance of the thermal index (material coefficient) B value: 395 × 10 (K)
 According to customer requirements, Provide different resistance, B value precision, Customize.
   When measuring NTC thermistors, the following must be observed:
• Can not be measured in air, The temperature difference in the air is bigger, Measurement is not accurate, Resulting in accuracy bias.
• Measurement using a high-precision thermostat, NTC into the thermostat after the test tank, After the temperature of the thermostat is stable, Can be measured.
• Measure voltage as low as possible,To reduce NTC self-heating caused by measurement error.
• For high temperature measurements,The temperature of the bath needs to be corrected and checked with a thermometer.
