Application Products

Used in temperature monitoring systems in industrial automation, such as for temperature protection of motors, conveyor belts, generators, and other equipment. NTC thermistors monitor temperature changes in real time, preventing equipment damage from overheating and ensuring the safety of battery management systems.

Widely used in temperature control systems in industrial automation equipment, they ensure stable operation of equipment (such as injection molding machines and drying equipment) during high-temperature processes. Temperature regulation through feedback control systems improves production process stability.

Used as a power supply protection component, they absorb voltage surges and prevent them from damaging control systems and other electronic devices. This is particularly true in motor drive systems and battery systems, ensuring long-term stable operation.

Provide overload protection and are widely used in automated production lines, conveyor belt power systems, and other applications. They automatically cut off the current when an overload occurs and automatically restore the connection when normal operating conditions return, protecting equipment from damage.

In electrical systems, GDTs absorb electrical surges and protect sensitive equipment from transient voltages. They are commonly found in power equipment, inverters, control systems, and other applications, ensuring safe operation.

Monitor the operating temperature of equipment to prevent overheating and damage. Thermal protectors are widely used in motors, power tools, and battery systems. If the temperature rises too high, they automatically shut off the power, preventing equipment failure and fire risks.

Used in power supply voltage stabilization systems, they prevent overvoltage damage to sensitive electronic components and ensure stable operation of industrial automation systems.

Convert AC power to DC power, providing a stable power supply. They are widely used in motor drive systems and power supply systems, ensuring the stability and reliability of the power supply for automated equipment.

In power systems, particularly motor control and power conversion systems, fast recovery diodes quickly cut off current and restore circuit operation, ensuring production line stability and efficiency.

Used in high-frequency power systems, they ensure power conversion efficiency, reduce energy loss, and enhance the performance of industrial automation equipment.

Widely used in power control systems, particularly in motor control, power conversion systems, and battery management, Schottky diodes offer low forward voltage and fast response, helping improve system efficiency and reduce energy loss.

MOSFETs are widely used in motor drives, power conversion, and power management systems. They efficiently control current flow, playing a particularly important role in variable-frequency drives, automated production lines, and robotic systems.

Used in high-power electrical equipment such as motor drives and step-up or step-down converters, they precisely control current flow, ensuring efficient operation and improving industrial automation efficiency.

Small Signal Transistors (SSTs) are used in signal processing and regulation systems to ensure control circuit stability. They are widely used in industrial automation control circuits, such as data acquisition and signal conditioning.
