Common Mode Chokes are types of inductors used to reduce the amount of unwanted electromagnetic interference (EMI) between source and load. The HM28-35042LF is a type of common mode choke that helps to suppress common-mode noise and control the flow of current to a desired frequency range. It features increased magnetic shielding, better impedance characteristics, and a two-layer magnetic shielding structure.

HM28-35042LF Common Mode Chokes are designed for low-frequency (LF) applications, such as Audio/Video (AV) signal lines, DC/DC converters, and power supplies. They feature a high inductance rating, low current draw, and high accuracy. They also can reduce wideband EMI. Additionally, they can reduce high-frequency interference, including power electronics, EMI from motors, and strong noise components.

The HM28-35042LF Common Mode Chokes are typically self-shielded, meaning the shield is automatically adjusted according to the inductance. This helps reduce noise without the need for additional shielding material. The design also features a two-layer structure, which helps ensure that the EMI suppression performance is maintained throughout its working lifetime.

The working principle of the HM28-35042LF Common Mode Choke is based on its self-shielding ability. The choke\'s magnetic core cuts down the flux leakage, which reduces the magnitude of the common-mode noise. The core material and assembly technique further enhance the effective suppression of the EMI. The choke also features a high impedance to reduce the flow of current and provide a layer of active shielding.

The HM28-35042LF Common Mode Choke is designed to provide effective EMI suppression without noticeable performance degradation. The choke also can withstand high-frequency interference (HFI) and provide high performance for long life. Additionally, the core material of the choke helps to reduce the magnitude of common-mode noise.

The HM28-35042LF Common Mode Choke features efficient EMI suppression, low current draw, and a two-layer structure. This makes it an ideal solution for many applications, such as Audio/Video (AV) signal lines, DC/DC converters, and power supplies. The choke\'s self-shielding and two-layer design helps reduce wideband EMI, while still maintaining high performance.
