Common mode chokes or common mode choke coils (CMCCs) are a type of electronic component employed for noise suppression and transient voltage surge protection within electrical and electronic systems. They are frequently used for the majority of digital-related applications, such as mobile phones, remote control cars, digital audio, digital video, and satellite receiver systems. The main purpose of these components is to block the flow of undesirable noise or transient voltage spikes, which are usually caused by switching, and prevent them from entering the system and affecting its performance.

One particular widely used CMCC model is the DLP1NDN900HL4L, which is a single-ended common mode choke. This model is equipped with two different types of coils, the first being a ferrite type coil for noise suppression and the second being a plastic-insulated coil for surge protection. It is designed to provide a low-loss, stable inductance with a wide range of inductance options. It has a maximum DC current rating of 9 Amps, a maximum AC voltage rating of 400 Volts, a low-inductance voltage drop of 0.3 Volts, and a dielectric withstanding voltage of up to 500 Volts.

This common mode choke type is particularly suitable for use in digital audio and video systems, computer systems, and consumer electronics due to its excellent suppression characteristics. It can help protect components by limiting the flow of transients, as well as suppressing high-frequency EMI/RFI interference, which can be generated from digital logic devices and other sources. It is also designed for use in power systems, such as automotive electronics, and is capable of providing a high level of transient voltage spike protection.

The working principle of the DLP1NDN900HL4L is based on the principle of inductance. It works by creating an electromagnetic field that limits the flow of currents into and out of the coil in order to restrict the flow of noise or transients. The coils in this model are designed with two separate paths. The ferrite type coil acts as a barrier to noise and transient voltages, while the plastic-insulated coil provides protection from transients and EMI/RFI interference.

In summary, the DLP1NDN900HL4L is a single-ended common mode choke that has excellent suppression characteristics and is suitable for use in digital audio and video systems, computer systems, and consumer electronics. It is equipped with two different coils, a ferrite type coil for noise suppression and a plastic-insulated coil for surge protection. It works by creating an electromagnetic field that limits the flow of current into and out of the coil, thereby limiting the flow of noise or transients. This makes it a reliable and effective device for protecting components from transients and EMI/RFI interference.
