Common Mode Chokes (CMC) are commonly used components in a variety of applications, such as line filters for power supply noise, home medical equipment, and industrial instruments. HM28-24013LF is one of the popular CMCs on the market today, and its excellent performance has made it a preferred product in a wide range of applications. This article will discuss the application field and working principle of HM28-24013LF.

The HM28-24013LF is a beaded inductor, with a rated inductance of 4.4μH and a rated current of 5Adc. It is also designed with excellent inductance tolerance, which makes it suitable for a variety of applications. HM28-24013LF can be used in SMPS/SPS circuits, networking systems, medical equipment, automotive applications, and other electronic systems. It is designed to provide excellent noise suppression and suppression of common mode currents.

The CMC of HM28-24013LF works on the principle of electromagnetic induction. It functions to reduce the amplitude of the common-mode noise on the power line, while allowing the signal or data line to remain undisturbed. When the current passes through the CMC, the coils in the device create a magnetic field, which induces a voltage across the CMC’s two terminals. This voltage is in opposite phase to the voltage in the power line. This results in the reduction of the common mode noise.

The performance of HM28-24013LF is further enhanced by its internal construction, which features a three-dimensional design that utilizes three layers of inner and outer coils to further reduce the noise in the common-mode current. This design effectively isolates the signal or data line from the power line, while providing superior noise isolation.

In terms of physical appearance, HM28-24013LF is a small device, with an overall size of 7.3mm x 5.8mm x 4.9mm. It has a minimum gap of 2.5mm between its two terminals, and a total height of 4.9mm. This makes it an ideal choice for use in electronic devices that require a small footprint. It also has an electrostatic discharge (ESD) protection rating of 8kV, which further ensures its durability.

Additionally, HM28-24013LF has a rated insulation resistance of 1kΩ, which makes it suitable for operating at higher temperatures. It is also designed to meet MIL-STD-202F standards, which makes it an especially reliable component for use in military applications.

In summary, HM28-24013LF is a highly reliable and versatile CMC that is suitable for use in various applications. Its excellent noise suppression coupled with its excellent insulation resistance makes it an excellent choice for power line noise suppression. Its small form factor, ESD protection rating, and MIL-STD-202F compliance further add to its appeal as a high-performance component.
