Overview

Integrated molded inductors are characterized by high saturation, low loss, strong electromagnetic interference (EMI) resistance, ultra-low buzzing noise, and high automation, making them widely used in various electronic devices. In the current integrated molded inductor market, painted and unpainted products are two common types. How to choose the right product has become one of the challenges for customers. The following discussion will focus on the characteristics of painted and unpainted integrated molded inductors.

Advantages of Painted Integrated Molded Inductors

1.By spraying an insulating protective film on the product surface, the entire outer layer of the product body is fully coated. During transportation, even in humid weather, moisture is less likely to penetrate the product and come into contact with the powder material, resulting in better rust prevention. 

2.The insulated protection added by spraying prevents the terminals from easily short-circuiting with the product body after bending. 

3.The insulated protection ensures the product has excellent insulation. Painted products can withstand external high voltages. 

4.With the insulating coating covering the product body, it is less prone to short-circuiting with other components when mounted on the circuit board. 

5.The surface spray coating allows the insulating layer to effectively penetrate the powder material. After high-temperature baking, it bonds tightly with the powder, making the product stable and reliable—it.It can be cleaned with weak acid or alkaline solvents.

Advantages of Unpainted Integrated Molded Inductors

1.The process is relatively simple with a higher degree of automated production, ensuring better product consistency and dimensional stability. 

2.Without the need for a painting process and with high automation in production, the price is more advantageous. 

3.The product body is exposed without coating, allowing faster heat dissipation.

Conclusion

Painted and unpainted products each have their own advantages. CODACA can provide you with two types of products with different processes: painted and unpainted. Painted products such as the CSAC/CSEB series can pass strict salt spray tests and can be used normally under the conditions of -40~+125℃. The unpainted product CSAB is die-cast with alloy powder materials with better rust prevention effects, with stable processes and a high degree of automation; at the same time, both integrated molded inductor products can pass the relevant reliability tests of AEC-Q200.
