In summer, the weather is urgent, and the incidence of fire accidents has also risen. In order to avoid the occurrence of fires, while strengthening people's safety awareness, it is also equipped with a more complete fire protection system and a sensitive fire alarm. In order to improve the sensitivity of the fire alarm device for smoke, Ampfort Electronics is recommended to place NTC thermistor to monitor temperature monitoring to help it better conduct fire detection.
The thermal resistance of epoxy packaging is generally a metal lead such as a tin -plated copper -plated steel wire or paint line line. After welding the thermist chip, it is wrapped in epoxy resin. This series of products can adopt different color epoxy resin, and the diameter of the lead is 0.25 ~ 0.5 mm.
Product characteristics: epoxy packaging, miniaturization, high accuracy; fast response time, good stability;
The main technical parameters:
1. By-based B value: 3000-4500k R25 ° C is a product with 0.5kΩ-2000kΩ.
2. Disposal coefficient (mW/℃): In the static air, about 2.1
3. Time constant (s): Static air ≤12
4. Work temperature range (℃): -40 ℃ ~+125 ℃
Scope of application: fire alarm, computer, copy machine, electronics calendar, thermometer, temperature control instrument and temperature compensation.
