Common Mode Chokes (CMCs) are used to isolate power supply, noise filters, pulse suppression, and in the EMC field. They can effectively reduce the common mode interference on the power line and equipment, so as to realize the reduction of electromagnetic radiation and the improvement of EMC performance.

The ELF-15N002A is an excellent Common Mode Choke from the JSHW Group. It is a double-core standard Common Mode Choke with a maximum rated current of 15A and an outer diameter of 28mm. It is built with two flexible cores, divided into four magnetic layers, and a high-frequency membrane. The two cores are combined to form a single-phase Common Mode Choke. The product is lightweight but durable, resulting in high-efficiency and low energy consumption.The ELF-15N002A is mainly used in the power supply system, power module, communication system, EMC filter and signal isolation. It can effectively suppress differential mode current and common mode current, and is widely applicable to various communication systems such as GSM/CDMA/WCDMA/PHS/TDSCDMA, as well as DTV/HDTV/IPTV and other advanced communication systems.

The ELF-15N002A works by clamping the outer shield (the common-mode line voltage) to the ground and absorbing the interference current flowing through the common-mode line. In this way, the interference current is harmonically converted into a low-frequency (LF) current, thus eliminating the interference energy. This current eventually circulates around the Common Mode Choke and returns to its original point, or the ground. In this way, the EMC performance is improved, making the ELF-15N002A an ideal choice for EMC applications.

The ELF-15N002A is also used for power supply isolation. It is capable of suppressing both common and differential mode noise. The common-mode noise current can be easily converted into the low-frequency component by the choke, which then circulates back to the ground, isolating the noise from the power supply. On the other hand, the differential-mode noise current can be suppressed by the magnetic fields generated between the two parts of the choke, reducing the noise on the power supply line.

In conclusion, the ELF-15N002A is an excellent Common Mode Choke from the JSHW Group. It is capable of suppressing both common-mode and differential-mode noise, resulting in improved EMC performance. It is a lightweight, durable, and energy-efficient product, making it an ideal choice for many power supply, EMC, and signal isolation applications.
