In electronic devices, if common-mode inductances have poor anti-interference capabilities, they can easily cause the equipment to malfunction due to interference from external noise. Moreover, if they cannot be compatible with High-frequency Transformer and Switching Power Supply Transformer, it can lead to installation difficulties. Jiuli has specially developed a series of common-mode inductances. Not only do they have strong anti-interference capabilities, but they can also precisely match these transformers, helping electronic equipment manufacturers solve the problem of inductors.
Product Description
Jiuli's Common-mode inductances adopt a ring-shaped core design, with the winding method optimized. The core is made of high-permeability ferrite material, which can effectively suppress common-mode interference signals. The inductors are wrapped with high-temperature-resistant insulating materials, with a temperature rating of up to 155°C, suitable for high-temperature environments inside equipment. The pin spacing and package size of these inductors are designed according to industry standards, allowing them to directly interface with the circuits of High-frequency Transformers and Switching Power Supply Transformers without modifying the PCB layout. They can be easily soldered over and have flexible adaptability.
Technical Specifications
From the parameters, the inductance value range covers 10μH - 1000μH, meeting the anti-interference requirements of different devices; the rated current is 1A - 20A, suitable for small-power household appliances and large-power industrial equipment; the common-mode rejection ratio (CMRR) is ≥ 60dB, with significant suppression effect on high-frequency interference. The model suitable for High-frequency Transformers has a working frequency of up to 50kHz - 1MHz, perfectly matching the frequency range of the transformer; the inductance corresponding to Switching Power Supply Transformers has a leakage inductance of ≤ 5%, without affecting the power conversion efficiency. Additionally, the insulation resistance of the inductors is ≥ 100MΩ, with AC voltage withstand of 2500V/1min without breakdown, ensuring electrical safety.
Product Features and Advantages
Jiuli's Common-mode inductances have outstanding advantages. Firstly, they have strong anti-interference capabilities. The high-permeability core and optimized winding can effectively filter out common-mode interference, making the equipment run more stably and reducing crashes and errors caused by interference. Secondly, they have wide compatibility, can precisely match High-frequency Transformers and Switching Power Supply Transformers, eliminating the need to design separate inductors for different transformers, saving the time for manufacturers' research and development. Thirdly, they are durable and resistant to high temperatures. The high-temperature insulating materials and solid workmanship make them less likely to be damaged in the long-term high-temperature environment of equipment, with a lifespan twice longer than ordinary inductors. Fourthly, they are easy to install. The standard packaging and pin spacing do not require circuit modification, and production line workers can solder them in a few minutes, improving assembly efficiency.
Application scenario
In the field of home appliances, in the power modules of washing machines and air conditioners, installing Jiuli's Common-mode inductances can suppress grid interference and prevent noise and malfunctions during equipment operation; in industrial control equipment, in the circuits of PLCs and frequency converters, using High-frequency Transformers together with them can filter out high-frequency interference and ensure precise control of the equipment; during the production of switching power supplies, installing them in conjunction with Switching Power Supply Transformers can enhance the electromagnetic compatibility of the power supply and comply with export certification standards; in the on-board chargers of new energy vehicles, the inductors have strong temperature resistance and can adapt to the high-temperature environment inside the vehicle, effectively filtering out interference and ensuring charging safety.
Customer Benefits
Choosing Jiuli's Common-mode inductances can save a lot of work for manufacturers. The equipment failure rate has decreased, and the anti-interference ability has made the post-sale problems of the products reduced by 30%, saving post-sale costs; the wide compatibility does not require separate research and development, shortening the product launch time; the convenient installation improves the production line efficiency, and 200 more devices can be assembled in a day. In the long run, the inductors have strong durability and do not need frequent replacement, which can also reduce the later maintenance costs, and the product competitiveness is enhanced, making it easier to pass electromagnetic compatibility certification and opening up domestic and international markets.
Customer Reviews and Recommendations
Mr. Zhang from an appliance factory said: "The common-mode inductors we used before had poor anti-interference performance, and the washing machines often reported errors. After replacing with Jiuli's, the equipment interference decreased, and the post-sale complaints were reduced by half, and it could be directly paired with our Switching Power Supply Transformer, which was very convenient." Mr. Li from an industrial equipment manufacturer commented: "Our frequency converters use High-frequency Transformers, and after using Jiuli's inductors, the control accuracy has improved, and it is stable in the complex power grid environment in the workshop. The customer feedback is very good." Mr. Wang, who makes switching power supplies, recommended: "This inductor has good temperature resistance and wide compatibility. When paired with Switching Power Supply Transformer, it can be used together, and the power supply EMC test passes once. Now we use Jiuli's for all our products, it is reliable."
