Exclusive Disclosure by Golden Eagle Coils - How to Control the Quality of Inductor Coils

As is well known, the key to the success of any product lies in its quality - whether it is good or not. Inductor coils are no exception.

When using inductance coils, various reasons often lead to problems with the quality of the inductance coils. So, what are the factors that affect the quality of inductance coils? Golden Eagle Coils, with 20 years of experience in the inductance coil industry, has sorted out and summarized these factors.

Be careful of the current in the inductor coil.

The inductor coil should be used within the designed rated current range and must not exceed the maximum carrying current; otherwise, it is prone to burn out.

2. Appropriate inductor packaging size and appearance

Although the corresponding performance parameters have been achieved, the inductor coil can theoretically ensure the desired performance of the inductor. However, during the manufacturing process of the finished product, the position of the inductor coil on the PCB, the selection of the appropriate installation method, the packaging size, and the appearance must also be considered to ensure the realization of the product.

3. It is essential to pay attention to the usage environment of the inductor coil.

When using inductance coils, it is essential to fully consider the working environment. Firstly, one should pay attention to the temperature and humidity of the environment where the product is located, as well as whether the surrounding electromagnetic interference sources will affect the normal operation of the inductance coil.

4. In the power circuit, the coil is prone to failure due to excessive current, which may cause it to burn out. It is possible that the filter inductor gets hot first, and in severe cases, it may burn out completely. At this point, the voltage output circuit of the power supply will be open, and the fault will manifest as no DC voltage output.

5. Selection of Wire Type and Wire Diameter

When selecting the most suitable wire for the windings of an inductor coil, it is advisable to choose from the commonly used inductor wires, which can help reduce costs.

6. Pay attention to the operating frequency of the inductor coil.

At low frequencies, inductors generally exhibit inductive characteristics and are mainly used for energy storage and filtering. However, at high frequencies, inductors show resistive characteristics, functioning as a resistor and accompanied by energy consumption and heat generation, as well as a decrease in inductive effect. The high-frequency characteristics of different inductors are all different.

7. Pay attention to the Q value of the inductor coil.

Take the magnetic ring inductance coil as an example. With the same inductance value, the choice of magnetic ring will vary, resulting in different final Q values. Therefore, based on the actual Q value requirements of the inductance coil, an appropriate magnetic ring should be selected.

8. Some fine-tuning coils may also exhibit incorrect inductance due to loose magnetic cores. At this point, the circuit where the coil is located will not function properly, manifesting as increased signal loss or no signal output at all.

The distinctive advantages of the inductor coils produced by Golden Eagle Coils:

All the machines are Daituo fully automatic winding machines. The equipment's repeatability accuracy is 0.001, which is probably beyond the capabilities of other companies.

2. The daily production capacity is 50,000 units. Perhaps there are not many companies in the country that can achieve this level of production.

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

4. The raw material wire brands are well-known suppliers in the industry: Yili Soller, Daihei of Japan, and Sumitomo.

5. 100% of raw materials and finished products undergo life reliability tests.

6. The factory area is nearly 30,000 square meters, so there is no need to worry about production capacity.

Golden Eagle Coils has outperformed its competitors with its excellent quality and service. Choosing Golden Eagle means choosing the right path to success.
