Facing a humid environment: How can the moisture resistance of inductor coils be enhanced?

In January, everyone in Guangdong was in the "natural refrigerator". In February, they were looking forward to a "new change" in the weather. Good news: The temperature has finally started to gradually rise this time; bad news: The dreaded "Moisture Return Spring" that Guangdong people hate the most is coming!

Inductors are an important component in modern electronic devices, playing a crucial role in electronic components. Inductors have the characteristic of blocking high-frequency signals and allowing low-frequency signals to pass through in circuits. This property is highly useful in circuits for filtering out harmonics. In humid environments, the insulating paint of inductors needs to have strong moisture resistance to prevent water penetration and ensure that the electronic magnetic rings can operate normally for a long time.

Insulating coating

Inductor coil insulating coating is a high-performance material specially designed to provide electrical insulation and a protective layer. This coating can effectively prevent moisture, prevent corrosion and wear, and ensure the stability of the electrical properties of the magnetic ring. To improve the moisture resistance of the insulating coating for electronic magnetic rings, the following aspects can be considered:

1. Material selection: Select a resin with excellent moisture resistance as the base material for the insulating coating, such as epoxy resin, silicone rubber, etc.

2. Coating Design: Design a reasonable coating structure to ensure that the insulating coating forms a uniform and continuous coverage on the surface of the magnetic ring.

3. Solidification process: Optimize the curing process of the insulating paint to ensure that no bubbles or pinholes occur during the curing of the coating.

4. Surface treatment: Perform appropriate pre-treatment on the surface of the inductor coil, such as sanding and cleaning, to enhance the adhesion between the coating and the surface of the magnetic ring, prevent the coating from peeling off during long-term use, and thereby improve the moisture-proof property.

5. Performance Testing: Through experiments simulating humid environments, the insulation coating is subjected to performance testing to evaluate its moisture-proof capability, and potential issues can be promptly identified and resolved.

By using the above methods, the moisture resistance of the insulating coating for the inductor coil can be effectively enhanced, ensuring that the electronic magnetic ring can operate stably and reliably even when exposed to a humid environment. The improvement and innovation of the insulating coating for the inductor coil have a significant impact on the long-term reliability and performance maintenance of electrical equipment. Therefore, investing resources in the research and optimization of this key material is of vital importance for the healthy development of the electronics industry.

The Golden Eagle Coil inductor has the following advantages:

All the machines are equipped with Jite automatic winding machines. The equipment's repeatability accuracy is 0.001, which is something that other companies may not be able to achieve.

2. The wire diameter can be as small as 0.012mm. There is no other company in China that can achieve this.

3. By adopting the lean production and one-piece flow production mode, quality abnormalities can be detected promptly.

4. The raw material wire for the coils is provided by well-known suppliers in the industry such as Yilisolo, Taihei, and Sumitomo. The quality of the wire is highly stable.

5. Achieved a quality record of "zero returns" for three consecutive years.
