Common Mode Chokes (CMC) are components which are used to suppress interference generated by high frequency signals. The HM28-24014LF is an example of one such component, which is designed for low frequency applications. This article will discuss the application field and working principle of the HM28-24014LF.

The HM28-24014LF is a 0.8mm maximum height CMC. It is suitable for use in signal line filtering applications with a maximum operating frequency of 1.3MHz. The component is designed for direct connection to digital signal lines, so it can be used to effectively filter out any high frequency signals generated by digital circuits. This makes it an ideal choice for applications such as power line filtering, audio line filtering, and the suppression of EMI.

The working principle of the HM28-24014LF can be described as follows. It contains two coils, one for the signal line and one for the return line. The signal line coil has an effective inductance of 8uH and the return line coil has an effective inductance of 3uH. These coils generate a magnetic field when current flows through them, and this field is used to suppress high frequency signals. The component also contains two capacitors, one between the signal line and the return line, and the other between ground and the return line. These capacitors serve to provide an overall high frequency passband for the filter.

In summary, the HM28-24014LF is a low profile CMC suitable for use in signal line filtering applications with a maximum operating frequency of 1.3MHz. It contains two coils and two capacitors, which together provide an effective filter for high frequency signals. The HM28-24014LF is an excellent choice for applications such as power line filtering, audio line filtering, and the suppression of EMI.
