Ferrite Cores - Cables and Wiring encapsulates a wide variety of components, like the SM28B2170-1, which is a highly efficient and compact radio frequency choke for high-frequency common-mode current noise suppression. It combines a high-frequency, high-permeability ferrite core, two conductors in an oxygen-free copper wrap. It is an ideal component to reduce radio frequency noise emissions from sources such as AC power cables, USB cables, Lightning cables, HDMI cables, and more.

The SM28B2170-1 application field mainly includes installations in sounds systems, PCs, HDTVs, digital cameras, telecommunication systems, and household appliances. With its compact design, the SM28B2170-1 can be easily connected to a host of systems and devices in order to reduce radio frequency interference. The working principle of this device is relatively simple: it suppresses common-mode noise current from single-phase AC power supply to components in the system. The choke will reduce the noise current by taking advantage of the characteristics of its ferrite core. When high frequency noise is present, the magnetic flux generated in the ferrite core produces an extremely high impedance that effectively attenuates the emitted noise.

This device is designed to meet the requirements of electromagnetic compatibility (EMC). It features a low frequency magnetic core for reducing common-mode current noise over a wide frequency range up to 27MHz while providing additional impedance to the current path at a much lower frequency range, all without introducing significant phase shift or insertion loss. Its unique design allows it to provide maximum effective suppression of radio frequency emission without affecting the performance of the device or any adjacent equipment.

The SM28B2170-1 can be used in a range of applications from consumer electronics to telecommunications. Its compact and lightweight design makes it easy to install and helps to reduce the overall cost of the system. Its high-frequency choking efficiency also ensures an effective noise reduction in a wide frequency range. This makes it one of the most popular RF chokes for EMC applications due to its affordability, efficiency, and easy integration.
