7,Packing
Packing shall be done not to cause damage or soil during delivery
MF59 glass-sealed thermistor NTC thermistor is a negative temperature coefficient thermistor. It is a high performance ceramic structure using a single high purity material with close to theoretical density. Therefore, in realizing miniaturization, it is also characterized by a small fluctuation in temperature of the resistance value, etc., and a quick response to temperature changes of various characteristics can be highly sensitive and high-precision detection. Our company provides small, high-reliability products in various shapes and features to meet customer usage requirements.
(1) Product features:
· The NTC chip is sealed in the glass, you can use it in any harsh
environment without worry.
· In order to ensure the heat resistance of the product, the
product is packaged in glass, which can work at a high temperature
of 300°C and is stable and reliable.
The resistance value accuracy is as high as 0.3℃, and the B value
accuracy is as high as 0.5%.
· The packaging method and results of its products determine the
fast response and high sensitivity.
· Due to its small size and light weight.
The resistance value decreases with the increase of temperature,
also known as linear negative temperature coefficient thermistor
· Since it is made of DHD, its mechanical strength is guaranteed
· SMT automatic device
(2) Scope of application:
· Office automation equipment.
· Air conditioning heating and cooling appliances.
· LED lighting, lithium battery temperature protection, mobile
phone battery.
· Hydraulic pressure sensor, medical equipment, electronic
cigarette.

Note: NTC thermistors of various specifications can provide
products with different R value and B value accuracy according to
customer requirements
(6) Precautions
1. LK-59 series thermistors are glass-sealed, please do not shake
or squeeze them to prevent the glass tube from breaking.
2. Do not test the LK 59 thermistor in the air. The temperature
difference in the air is large, and the measurement is very
inaccurate. It often produces a deviation of more than 1-2°C. It
must be measured with a high-precision constant temperature oil
tank. After entering the constant temperature oil tank, the
temperature of the constant temperature tank must be stable before
measurement.
3. The voltage should be as low as possible during measurement to
reduce the measurement error caused by NTC self-heating.
4. When measuring high temperature, it is necessary to use a
thermometer to correct and check the temperature of the constant
temperature tank.
