Common Mode Chokes

Common Mode Chokes, also known as EMI filters, are electrical components that reduce the amount of electromagnetic interference (EMI) from one device to another. They are usually placed between the power line and the device that will be affected by any interference. The LF2115NP-183 is an example of a Common Mode Choke.

LF2115NP-183 Application Field

The LF2115NP-183 is mainly used in circuits with high frequency signals. They are specially designed for the protection of high-speed digital and communication equipment. Examples of equipment that would benefit from a LF2115NP-183 include LCD monitors, test and measurement equipment, set-top boxes, radios, and medical equipment. This filter is especially useful for reducing interference from Switch Mode Power Supplies (SMPS). As SMPS typically have large amounts of EMI, the LF2115NP-183 helps to reduce that EMI and improve the performance of the device.

LF2115NP-183 Working Principle

The LF2115NP-183 is an inductor-based EMI filter. An inductor is an electrical component that produces an inductance when exposed to an alternating current. Inductors are used to reduce the amount of EMI produced by the SMPS.The LF2115NP-183 works by allowing a low-voltage direct current (DC) to pass through the inductor, while blocking high-frequency alternating current (AC). This reduces the amount of EMI that passes through the circuit. The LF2115NP-183 also contains a capacitor, which helps to filter out low frequency EMI.

Conclusion

The LF2115NP-183 is an example of a Common Mode Choke, which is used to reduce the amount of EMI generated by Switch Mode Power Supplies (SMPS). This filter works by allowing a low voltage DC to pass through the inductor, while blocking high-frequency AC. The LF2115NP-183 is mainly used for the protection of high-speed digital and communication equipment, as well as any other device that is affected by EMI.
