Good consistency thermistor chip in China

Short Description:

Compared with other peers in China, the consistency of all parameters of our chip is very good, and the result of the high temperature experiment is absolutely outstanding. Seasoned chip experts should know above 250 ° C, every increase of 10 ° C aging, the resistance value change rate will generally double or more, our chip at 260 degrees for 10 days, the resistance value change rate is less than 1%.

High Precision NTC Thermistor Chip (NTC Temperature Sensor Chip)

NTC thermistor chips are high precision bare chips with gold or silver plated surface as electrodes, and are suitable for mixed-design multifunctional modules for hybrid applications using bonding wires or gold or manganese solder as the connection method. They can also be directly soldered to tinned, nickel-plated or silver-plated wire to make temperature sensors.

To use NTC for temperature measurement and control, it is generally necessary to encapsulate the NTC chip with glass or epoxy resin into a variety of plug-in and thin-film NTC thermistor components.
NTC thermistor components in many applications can be directly used to measure temperature and control temperature through proper installation, but more is to further encapsulate the thermistor into different materials and shapes of the probe shell, and thermistor leads will be connected with wires of different specifications and lengths, then assembled into temperature sensors to measure and control temperature.

Features:

1) Can be applied to bonding process, using gold/aluminum/silver soldering wires;
2) High accuracy up to ±0.2%, ±0.5%, ±1%, etc.
3) Good heat cycle resistance;
4) High stability and reliability;
5) Miniature size

Applications:

 Thermistors for Automotive (Seat heating systemEPAS, Air suspension system, Car mirrors and steering wheels)
 Bonding (infrared thermoelectric reactor, IGBT, thermal printing head, Integrate module, semiconductor module, power moulde, etc)
Medical temperature sensors ( High-precision Disposable and Reusable temperature probes)
Wearable intelligent monitoring ( Jacket , Vest , Ski suit , baselayer, gloves , Cap socks)
