Common Mode Chokes are a type of filter that is used in electronic transmission and reception lines. The HM28-32018LF is an example of one such choke, designed for use in CAN-bus applications. In this article we will look at the application fields of HM28-32018LF, as well as look at its working principle.

The HM28-32018LF is a multi-stage high performance common mode choke designed to reduce noise and interference in CAN-bus applications. It features a small profile and low profile design, meaning it can be easily mounted onto a board without taking up too much space. It\'s also wide temperature range allows it to be used in a variety of different environments. In addition, the HM28-32018LF is equipped with a range of various input/output power levels, making it suitable for different input and output signals.

The key feature of the HM28-32018LF is its ability to reduce noise and interference in CAN-bus systems. It does this by utilizing three stages of common mode suppression and a twenty-five turn coil construction. The three stages of common mode suppression increase the attenuation of the interference signal while the twenty-five turn construction works to reduce the inductance of the choke, resulting in a lower noise level.

In addition to CAN-bus applications, the HM28-32018LF can also be used in audio, automotive, and other industrial applications. It is highly effective at reducing noise in audio systems, due to its low-inductance design and effective common mode suppression. In automotive applications, the HM28-32018LF is able to reduce the noise and interference caused by electrical noise from other sources. Finally, in industrial applications, it is often used to reduce electrical interference from multiple sources.

The working principles of the HM28-32018LF are fairly simple. When an input signal is applied, the amount of current that can be transmitted is limited by the inductance of the choke. This is due to the fact that the current is blocked by the choke, resulting in a reduction of the voltage across the choke which reduces the amount of current that can be transmitted. In addition, the inductance of the choke also works to reduce the noise and interference in the signal due to the frequency-dependent reactance of the choke.

Overall, the HM28-32018LF is a very versatile and effective common mode choke designed for use in CAN-bus and various other applications. Its three-stage common mode suppression and low inductance design make it ideal for reducing noise and interference while its wide temperature range ensure it will perform reliably in any environmental conditions.
