Common mode chokes provide electromagnetic shielding effectiveness and filtering in many types of electronic systems. The HM28-32023LF common mode choke is an example of a filter for signal and power wires. This type of common mode choke is typically used in high-speed data communication networks, telecommunications, and power supplies, as well as other applications.

The HM28-32023LF common mode choke can provide a frequency response of up to 28GHz, while providing excellent shielding performance. It offers a wide range of operating temperatures, from –55 °C to + 125 °C. Its package is a 4-pin, surface mount, and lead frame-based package.

The HM28-32023LF common mode choke is designed to reduce EMI (electromagnetic interference). It works by attenuating signals at certain frequencies, while isolating energy on different conductors. As a result, EMI will not be transmitted to other parts of the circuit. The choke also prevents interference from incoming or outgoing signals.

The HM28-32023LF common mode choke utilizes a high-quality magnetic material for increased shielding effectiveness. This material is extremely stable, and can reduce EMI in both high-frequency and low-frequency ranges. The choke also provides a low DC resistance path and low inductance, making it suitable for high-speed data applications.

The HM28-32023LF common mode choke offers a compact size, making it ideal for applications with space constraints. It also offers excellent performance-to-cost ratio and provides a reliable solution to EMI issues. In addition, it can be implemented in high-speed digital signal processing systems, where shielding performance and signal integrity must be maintained.

The working principle of the HM28-32023LF common mode choke is based on electromagnetic induction. This means that a current in one wire induces a voltage in another wire. The choke works by attenuating or isolating signal current at certain frequency ranges. For example, an inductor with a certain frequency will provide higher attenuation for signals with frequencies above its cutoff frequency, while a capacitor with a certain frequency will block signals with frequencies below its cutoff frequency.

The HM28-32023LF common mode choke can be used in a variety of applications, such as in switch-mode power supplies, in automotive systems, and for in-home networks. It is also used in telephone and signal line protection in harsh environments. Since it features a high-quality magnetic material, it provides increased shielding effectiveness and excellent signal integrity.

The HM28-32023LF common mode choke is an ideal choice for applications where EMI suppression is of the utmost priority. With its wide temperature range, compact size, and excellent performance-to-cost ratio, this type of common mode choke can provide a reliable solution for reducing interference in any type of system.
