The power and industrial control industries commonly face problems such as strong common mode noise interference, filter failure under high current conditions, mismatch of standard components, and lack of testing standards, which directly lead to non-compliance of equipment EMC, decreased stability, and prolonged development cycle. These problems will increase rectification costs, delay mass production, and affect the competitiveness of end products. As a professional solution provider, JIU LI has launched a full range of high current common mode chokes and 2A common mode chokes, covering both standard and customized requirements, while providing complete testing and application support to help customers quickly pass EMC certification, improve power supply reliability, and shorten the development cycle.
The products are mainly used in the Power supply common mode choke scenario, suitable for switching power supplies, adapters, industrial drives, communication power supplies, etc., responsible for suppressing conducted common mode interference and ensuring the stable operation of the system. We provide flexible customization as a Custom common mode choke supplier, from parameters, structure to installation methods, all can be adjusted, and clearly define the standard process of How to test common mode choke, including key items such as inductance, impedance, insertion loss, and saturation current, to ensure that the performance of each product can be quantified and traced. Product Features
With the adoption of high magnetic permeability cores and low-resistance windings, it is less prone to saturation under high current, and has a wide frequency band filtering stability.
It covers all specifications from 2A to large currents, with both standard products and customizations available, and can quickly adapt to different power supply architectures.
It comes with a complete test scheme and report to help customers implement How to test common mode choke, reducing verification costs.
Tips:
The selection should be based on the actual peak current multiplied by 1.2 or more to avoid performance degradation under high temperature and heavy load.
During testing, the same frequency and bias conditions should be used to ensure data comparability and facilitate batch consistency control.
JIU LI always focuses on power supply filtering and EMC scenarios. With reliable high current common mode choke and customized services, it provides customers with a full chain support from selection, testing to mass production, steadily improving power supply quality and equipment anti-interference ability, reducing after-sales and rectification risks, and becoming a trustworthy partner in the power supply and industrial control fields.
