Common Mode Chokes can be used as EMI/RFI filters, power line chokes, EMI suppressor for pulse noise, signal lines, and current blocking. They are commonly used in power filtering applications such as medical, telecommunications, and industrial equipment.The HM28-24010LF is one of the most popular common mode chokes. It is a two winding 15 A rated coil, designed as an EMI/RFI filter to attenuate differential mode and common mode currents. The coil has two windings connected in series, each winding having an inductance of 28 nH and a current rating of 10A.The operating temperature range of the HM28-24010LF is from -40°C to 125°C with a rated current of 15A. The core material is RI8 and the impedance is 25 Ohms. It is RoHS compliant and UL certified.The commonly used applications include audio, computer, data communication, automotive, and consumer electronics equipment. It can be used for reducing emitted noise, which helps to reduce EMI radiation in all kinds of equipment.The working principle of the HM28-24010LF is to oppose the change of magnetic flux in both sources and loads. When an EMF is generated due to the changing magnetic flux, a current proportional to the EMF is induced. The HM28-24010LF then resists the flow of this induced current, due to the high inductance. This contributes to decreased impedance levels.The HM28-24010LF works by providing low differential mode impedance, as well as high common-mode impedance. The differential mode impedance is designed to be low in order to allow currents to pass between sources and loads without much interference. The common-mode impedance, however, is designed to be high in order to reject interference that is external to the circuit in which it is connected.The "LF" at the end of the product code denotes a "low frequency" version of the product. This means that the HM28-24010LF has an extended frequency range and can be used for applications that require higher frequencies.In conclusion, the HM28-24010LF is a two winding 15A rated coil that can be used as an EMI/RFI filter to attenuate differential-mode and common-mode currents. It has a working temperature range from -40°C to 125°C and is available in a low-frequency option that extends its frequency range. The HM28-24010LF is commonly used for audio, computer, data communication, automotive, and consumer electronics equipment, and can be used for reducing emitted noise and EMI radiation.
