Anyone who makes switching power supplies knows that choosing a common mode inductor can be quite troublesome - the parameters are hard to understand, choosing a large one costs money and takes up space, choosing a small one exceeds the EMI standard and fails the certification, and it is also prone to magnetic saturation failure. Re-working is time-consuming and costly. As a reliable Common mode choke manufacturer, JIU LI directly helps you solve this problem: make custom common mode inductors as needed, and pair them with dedicated Power supply common mode noise filter. They precisely match the power and frequency of your switching power supply. You don't have to guess blindly. Once you make the right choice, you can pass the EMC certification, ensure the stability of the power supply, and save a lot of selection and rework costs.
To put it simply, the purpose of this common mode inductor is very clear - it is specifically designed to deal with the common mode noise generated during the operation of the switching power supply, preventing interference from entering the power supply and not allowing the power supply to interfere with surrounding equipment. It can be used in both household adapters and industrial switching power supplies. The core value is to help you save the trouble of selection, avoid magnetic saturation, EMI超标， and other pitfalls， avoid repeated rectification， ensure stability in batch production， comply with ROHS environmental protection requirements， and use solid materials without cutting corners.
The product features are just three points. They are not empty promises; they are all things that can be felt through actual operation:
1. Customization is highly precise: No matter what current and frequency band your switching power supply has, we can precisely customize Custom common mode inductor. There's no need to force the use of general models to make up for it. This avoids parameter mismatch issues that may lead to failure, and we can also adjust the size according to your PCB layout.
2. Excellent Filtering Performance: The Power supply common mode noise filter of JIU LI uses high-quality magnetic cores and has a solid winding process. It can efficiently filter out common-mode noise and has excellent EMI suppression effect. This helps you easily pass the certification without the need for repeated rectification and testing, saving time and cost.
3. Durable and Easy to Install: Excellent heat dissipation performance, it won't overheat during long-term operation, is not prone to magnetic saturation, easy to install, compatible with the compact layout of switching power supplies, can improve efficiency during mass production and reduce troubles in the production process.
There are just two tips for model selection, both of which are proven strategies we have accumulated over the years in this industry:
When choosing the type, only consider the inductance value. Make sure to inform JIU LI of your switch power supply's rated current, operating frequency, EMC certification requirements, and actual working conditions. Only then will the customized product be accurate. Don't fall into the trap of mismatched parameters.
2. Don't blindly increase the inductance value. An excessively high inductance can affect the normal operation of the switching power supply and also increase losses. As a professional Common mode choke manufacturer, we will provide you with the best suggestions based on your requirements. It's convenient and reliable.
In summary, when choosing switching power supply common mode inductors, there's no need to blindly search for parameters or test products on your own. Just contact JIU LI and you'll be right. Customized models have strong adaptability and guaranteed filtering effects, helping you save time and costs. Once you make the right choice, there's no need for rework. This completely resolves the troubles associated with model selection.
