NR magnetic adhesive inductor is a commonly used inductor component in electronic circuits. With its unique structural design and excellent performance, it is widely applied in various electronic devices. The origin of its name mainly stems from two core characteristics:
A thick layer of magnetic adhesive material is coated on the surface of the copper wire of the product. This design can significantly improve shielding performance, effectively reduce electromagnetic interference, and at the same time protect the internal copper wire structure to extend the service life of the product. Hence, it is named "magnetic adhesive inductor".
This type of inductor was first launched in Japan in the early days, which gained wide recognition in the industry. "NR" has been long used as its iconic code name, so it is commonly referred to as "NR inductor" in the industry. In addition, since the product can be mass-produced by fully automated machines and is compatible with surface mount technology, it is also called "automated surface mount power inductor".
In the early days of NR magnetic adhesive inductors, all processes such as wire winding and assembly were done manually, resulting in low production capacity and high unit price. With the development of high-tech and modernization, NR magnetic adhesive inductors now support fully automated machine manufacturing. It features high production efficiency and good product consistency, which can greatly reduce labor costs. Meanwhile, it ensures the stable performance parameters of each batch of products and reduces quality differences caused by manual operations, making it suitable for the production needs of large-scale electronic manufacturing industry.
