Common Mode Chokes

Common mode chokes (CMCs) are components used in electronic circuits to reduce the amount of interference caused by electromagnetic interference (EMI) and radio frequency interference (RFI). CMCs are used primarily in power supplies, converter circuits, and signal lines.The SS28H-R20130-CH is a common mode choke used in such applications. It is manufactured by Shenzhen Wisdom Technologies Co., Ltd. and comprises a coil with two sides connected back to back. This configuration generates a strong magnetic field that acts as an impedance to any outside interference. The SS28H-R20130-CH is a compact, low-cost device ideally suited for applications in industrial, commercial and consumer electronics.The SS28H-R20130-CH has a wide range of applications, including motor-drives, switching and DC/DC converter circuits, LED displays, home appliances, and circuit protection. The choke helps prevent the transfer of EMI and RFI noise from external sources, resulting in improved system performance. Additionally, the device can be used to filter high frequency noise in normal mode, as well as low-frequency, wideband, and power line noise in common mode. The working principle of the SS28H-R20130-CH is based on the concept of reactive impedance. When electronic devices use signals of alternating current frequency, the electromagnetic field generated by the signal affects other components connected to the same circuit. This is where the choke comes in. By introducing an inductive reactive component, the device acts as an impedance to the external interference, intercepting the noise signal and effectively reducing its impact on the circuit.The SS28H-R20130-CH provides low-cost shielding and EMI suppression in power supplies, converter circuits and signal lines. It can be used with either AC or DC current supply and can be applied in both normal and common modes. The device is suitable for use in a variety of applications such as motor-drives, switching circuits, DC-DC converters, LED displays, home appliances and circuit protection. Overall, the SS28H-R20130-CH is a reliable and cost-effective solution for suppressing EMI and RFI noise in a wide variety of applications. Its compact design and operating characteristics make it ideal for a wide range of applications. The device is easy to integrate into existing circuits and provides superior shielding for electronic components.
