In the design of SMPS (switching power supply), the selection of common mode choke coils is prone to fall into the misconception that "the higher the sensitivity, the better". This often leads to problems such as failure in EMC testing, unstable equipment operation, and interference leakage, which not only delay project delivery but also increase debugging and rework costs. To address this issue, as a professional Common mode choke manufacturer, JIU LI provides exclusive selection solutions. The core includes toroidal common mode inductors and SMD 10mH 1A common mode chokes for switching power supplies, etc., which are compatible products that precisely match the interference suppression requirements of SMPS design. They effectively reduce common mode noise and help equipment smoothly pass EMC certification, improve operational stability, and are widely used in various scenarios such as various switching power supplies, power adapters, industrial control power supplies, etc. They balance performance and cost, providing worry-free and efficient core component support for SMPS design.
JIU LI focuses on the research and production of common mode choke coils. By combining the high-frequency interference characteristics of SMPS design, it optimizes the product structure and material selection. The toroidal common mode inductor adopts a ring-shaped core design, with symmetrical winding of the coils, reducing parasitic capacitance and leakage inductance, and improving the interference suppression efficiency. The SMD 10mH 1A common mode choke for switching power supply is suitable for miniaturized SMPS design. It is in a surface mount package, facilitating automated assembly. With a 1A rated current and 10mH inductance, it precisely matches the interference suppression requirements for both medium and low frequencies, and also meets the compatibility requirements for different power switching power supplies. All products have undergone strict testing, demonstrating strong stability and high temperature resistance. They can effectively prevent the attenuation of inductance due to core saturation, ensuring the long-term stable operation of SMPS.

Tips
1.When selecting the type, there is no need to blindly pursue high sensitivity. Instead, it is necessary to combine the switching frequency of the SMPS, the interference frequency band, and choose either JIU LI Toroidal common mode inductor or SMD 10mH 1A common mode choke for the switching power supply. This is to avoid the saturation of the magnetic core and its impact on performance.
2. During installation, ensure that the SMD 10mH 1A common mode choke for the switching power supply is placed flatly, close to the interference source of the SMPS, and minimize the lead length to further enhance the interference suppression effect.
As a reliable manufacturer of common mode chokes, JIU LI has always focused on the pain points in the design selection of SMPS. With high-quality toroidal common mode inductors, SMD 10mH 1A common mode chokes for switching power supplies, etc., it provides engineers with precise selection solutions, helping to improve the quality and efficiency of SMPS design and ensure its smooth implementation.
