HGTECH VT/LT/AT Series heat-sensitive semiconductor resistors

HGTECH VT/LT/AT series heat - sensitive semiconductor resistors are NTC (Negative Temperature Coefficient) thermistors with their own characteristics and application scenarios. The following is a detailed introduction:

VT Series: It is a kind of NTC thermistor for automotive use. It has the characteristics of high - precision and high - stability, and is encapsulated with epoxy resin, which endows it with good heat - resistant cycle ability. It can quickly respond to temperature changes, and its working temperature range is - 50℃~125℃. This series of thermistors is mainly used in automotive oil temperature and water temperature sensors, as well as intake air temperature sensors, etc.

AT Series: It is a high - precision thermistor. When used as a temperature measuring instrument, the AT thermistor does not require adjustment between the control circuit and the sensor, which can ensure that the temperature is accurate to ±0.3℃, making the temperature indicator and control equipment operate more reliably. It is mainly used for temperature detection and control of household appliances, such as air - conditioners, refrigerators, microwave ovens, etc., and can also be used for temperature detection and compensation of office automation equipment.

LT Series: There is no public information indicating that HGTECH has an LT - series heat - sensitive semiconductor resistor product for the time being. However, in other brands, the LT series usually represents high - power leaded chip terminations, such as the LT series of KYOCERA AVX. If HGTECH's LT series also belongs to this type, it may have the characteristics of high - power resistance, with a nominal impedance of about 50Ω, a resistance tolerance of ±5% as standard (±2% is optional), and a temperature coefficient of ±150 ppm/℃, which is applicable to high - power RF amplifiers, instrumentation and other fields. But this is only a speculation based on the product characteristics of other brands, and the specific situation needs to be subject to the official introduction of HGTECH.
