Product Introduction

----------------------------------------------------------------------

What Is Glass Sealing Thermistor
Glass thermistor is a glass-sealed thermistor. Common glass sealing thermistor are: single-ended glass thermistor, diode glass seal, SMD glass seal. Because of the glass insulation, the thermistor is not affected by the additional temperature, greatly improving the sensitivity and accuracy of the control.


Glass Sealed Thermistor Characteristics
High interchange accuracy
Excellent solderability and thermal shock resistance
Wide operating temperature range
Excellent moisture resistance
Low loss, small size
Automated mass production to ensure that the products of high quality and high stability


Composition Structure And Production Process
1> single-ended glass seal: thermistor chip and copper wire welding, use a bead-like glass case package. Single-ended glass-type products are the smallest thermistor.
● lead package allows for manual or machine is mounted;
Single - ended glass thermistor structure diagram
● Packing: 1000 pcs / bag;
● Dissipation factor: ≥2mW / ℃ (in still air)
● Thermal time constant: ≤ 20S (in still air)
● Rated power: ≤ 50mW
● Note: When installing the product, two wire can not touch.
