What is a high-precision humidity detection axial glass-sealed thermistor?

At present, the glass-sealed resistors are mainly packaged in radial directions, and the dissipation factor is above 0.5mW/℃. Radial glass-sealed thermistors are affected by structure and dissipation factor, and are not suitable for high-precision humidity detection

What is the dissipation factor？

Dissipation factor (δ) is power in milliwatts required to raise thermistor temperature 1℃, measured with thermistor suspended by its leads in a specified environment.

The high-precision humidity detection axial glass-sealed thermistor developed by Exsense Sensor uses two pins of the glass-sealed thermistor on both sides (axial) of the chip, and the dissipation factor is within 0.25mW/℃ , When lower power is loaded on the glass-sealed thermistor, the glass-sealed thermistor can heat up to 180℃～200℃ in a short time, and it is suitable for high temperature occasions.

It has a smaller size, the size of the glass head after packaging is only 0.6MM, and it has a lower dissipation factor, and the leads are made of alloy wires on both sides of the chip; the chip uses lower resistance and higher B value Features: The alloy wire and the chip are glued together with silver paste, and the two alloy wires are on both sides of the chip; the glass shell is placed on the bonding position of the chip and the alloy wire; the glass shell is fired into a drop shape at high temperature. The pins are not on the same side, which is more convenient to use.
