Common mode chokes (CMCs) are devices used to reduce the undesirable flow of electricity and are employed in pairs of inductors to reduce the level of common mode currents in electronic equipment. The SRF2012-900Y application field and working principle can be further summarized in the following passages.
The SRF2012-900Y is a common mode choke ideal for line-by-line emission reduction in AC/DC power supplies, inverters, and lighting applications. Features include a low ESL and good temperature stability. The common mode inductance range is from 0.1 to 10 mH, and the rated current is up to 10A.
The unit’s characteristic impedance of the winding helps to reduce the adverse effects of high frequency noise, as well as to suppress the transmission of common-mode signals. The excellent temperature stability of the SRF2012-900Y also ensures proper electrical performance over a wide temperature range of -30℃ to +125℃. This permits the use of the device in many critical applications in the areas of communications, sensing, etc.
The working principle of money common mode chokes consists in the generation of a magnetic field that works against the high frequency noise, thus suppressing its propagation and hence, attenuating its intensity. When the high-frequency current flows through the cross-wound windings of the common mode choke, they create a magnetic field that rejects the voltage waves that flow through the common. The magnetic field also aggravates the higher frequency components of the noise, resulting in reduced current flow in the circuit.
The SRF2012-900Y feature low insertion loss and low series inductance. The reduction in insertion loss is due to the low inductance of the windings and the low reactance of the device. To further increase insertion loss reduction, the SRF2012-900Y employs ferrite cores, which can reduce series inductance values significantly. The ferrite core material is also resistant to corrosion and has a high temperature tolerance, and hence, the device can be used in a wide variety of applications.
The SRF2012-900Y also exhibits good EMC performance. By employing the device in pairs, the level of common mode currents are greatly reduced. The reduction in common mode current prevents interference from outside sources, thus preserving the quality of high-frequency signals.
In conclusion, the SRF2012-900Y is a common mode choke that is ideal for line-by-line emission reduction in AC/DC power supplies, inverters, and lighting applications. It is designed to reduce the levels of common mode currents in electronic equipment, which prevents interference from outside sources. Its low insertion loss and series inductance, combined with a ferrite core material, further enhance its performance.
