MF5A 503 3950 temperature measuring type high temperature resistant thermistor is suitable for power supply hygrometer
MF52 small leather wire NTC thermistor
MF5A NTC Thermistor Description:
MF5A-503F R25=(50K) B25/50=3950±1% High-precision small-volume negative temperature coefficient thermistor powder preparation to NTC chip coating full-set manufacturer Dongguan Linkun Electronic Technology Co., Ltd.
NTC (Negative Temperature Coefficient) thermistor is a resistor with high temperature coefficient and is also a semiconductor element that is extremely sensitive to temperature. It is made of metal oxides such as manganese, cobalt, nickel, and copper, and is manufactured by ceramic technology. It is formed, because its conduction method is completely similar to semiconductor materials such as germanium and silicon. When the temperature is low, the number of carriers (electrons and holes) in these oxide materials is small, so the resistance value is high. As the temperature rises, the carrier As the number of carriers increases, the resistance value decreases.
MF5A small leather wire thermistor features:
• NTC temperature sensor is small in size and fast in response
• NTC leads are insulated, and the wires are soft and can be bent moderately
•Thermistor resistance value B has high precision and accurate temperature measurement
• NTC chip products are lead-free and comply with the EU ROHS directive
Application scope of thermistor and NTC temperature sensor:
• , vacuum gauge, temperature and humidity gauge, beauty equipment, power supply, electronic toys
• Cell phone batteries, NB batteries, electric vehicle batteries, medical instruments for gas analyzers

Precautions for the use of small leather wire thermistors:
Be sure to use within the specified temperature range to avoid deterioration of the material and characteristics.
Thermistors are designed based on transformers used in general (indoors at room temperature, humidity, and pressure). Therefore, if they are used in the following environments, they will fail (or burn out) when the characteristics are worst. ), please do not use in such an environment.
① Corrosive reducing gases (Cl2, HXS, NH3, SOX, NOX, etc.).
② Among volatile and flammable gases.
③ Places with a lot of dust.
④ A place where pressure has been reduced or increased.
⑤ Places in direct contact with water or places that are prone to condensation due to high humidity.
⑥ Place in salt water, oil, liquid medicine, organic solution.
⑦ Places with excessive vibration.
⑧ Other places similar to ①—⑦.
Small leather wire thermistor abnormal handling:
When the thermistor is abnormal, short-circuit current will pass through, and there may be abnormal smell, abnormal sound, smoke, etc., please be sure to connect the thermistor in series with the current protection as another protection device.
When the thermistor is working, depending on the site (environment) conditions, it may exceed 110°C. Please confirm whether it affects surrounding parts or materials.
Abnormalities in thermistors not only affect parts or materials and cause them to deteriorate, but gas emitted from parts or materials often becomes the cause of component deterioration.
