AMPRON
NTC thermistors for temperature sensing and inrush-current limiting
About the manufacturer
Shenzhen Ampron Sensitive Components Co., Ltd. specializes in temperature-sensitive resistive components, primarily NTC thermistors. These devices use the temperature dependence of resistance and can therefore operate as sensors, compensation elements or inrush-current limiters.
The manufacturer offers thermistors with different resistance values, B constants, body sizes and current ratings. This makes it possible to select components both for temperature monitoring and for protecting the input stages of power supplies, chargers and equipment with high input capacitance.
The simple construction, compact size and broad range of characteristics make Ampron thermistors suitable for volume designs where cost, repeatability and easy integration are important.
Applications
Ampron NTC thermistors can be used in both sensing circuits and power-input stages. Typical applications include:
- Temperature sensing – monitoring components and ambient conditions.
- Temperature compensation – correcting temperature-dependent circuit parameters.
- Power supplies and converters – limiting inrush current at power-on.
- Chargers and mains-powered equipment – protecting input capacitors and rectifier bridges.
- Appliances and HVAC – temperature sensing in control systems.
- Industrial electronics – thermal monitoring of modules and power circuits.
