Common Mode Chokes are one of the most common power solutions used in a variety of industrial, consumer, and medical applications. HM28-32024LF is a common mode choke, which is widely used in various applications to reduce harmful noise and for overvoltage protection. It features a compact size, excellent heat resistance, and high reliability.

HM28-32024LF application field mainly include AC adapter, power supply, charger, motor drive, LED lighting, etc. The working operating temperature range is -55℃ to 130℃ and the maximum rated current up to 15 A. By suppressing common mode noise, which is the EMI noise generated in the power line, and blocking high voltage throughout, the common mode choke can provide the most effective protection against power cross-over components, extending the service life of the related equipment.

The main working principle of HM28-32024LF is to reduce the transmission of common mode noises by creating a strong electromagnetic field. This electromagnetic field is generated by current circuits that flow through the series of inductors which form the common mode choke. The way the current flows through the inductors will depend on the shape and size of the core. The inductors act as an energy storage and release system when the current begins to flow. The current is forced into a vertical position, causing the inductors to create an opposing force to the current, reducing the transmission of common mode noise.

HM28-32024LF is composed of an unusual combination of amorphous core and ferrite core, which enables it to attain an optimal balance between common mode impedance and dc impedance. With the optimized combination of amorphous core and ferrite core, the common mode inductance can reach 0.50uH/100mA at 1KHz and the DC resistance can reach 0.35mΩ. Furthermore, the HM28-32024LF also incorporates a unique super-rigid structure, which ensures excellent transmission attenuation performance. This common mode choke is perfect for applications that require high quality, low cost, and reliable noise reduction.

In summary, HM28-32024LF is a type of Common Mode Choke, designed to reduce common mode noise and prevent overvoltage in a variety of industrial, consumer and medical applications. It has excellent performance characteristics suitable for current requirement in power supplies, AC adapters, chargers, motor drive and LED lighting. With its compact size, heat resistance and reliability, HM28-32024LF is a great cost-effective solution for electrical noise reduction.
