CST series patch integrated molding
Product introduction: As a very popular inductor product, CST series integrated inductors have a lot of domestic users' needs, which has caused the market for integrated inductors to be confused. Many domestic integrated inductor manufacturers have serious quality problems.
As a very popular inductor product, integrated inductors have a lot of demand from domestic users, which has caused the market for integrated inductors to be relatively confused. Many domestic integrated inductor manufacturers have serious quality problems. The following editor from Suzhou Gujing Electronics Explain in detail.
In the process of manufacturing integrated inductors, some domestic manufacturers of integrated inductors did not meet the standard production environment and selected inferior raw materials, resulting in product problems with integrated inductors.
The one-piece inductor iron powder must be equipped with volatile organic chemicals such as acetone. Organic chemicals are easily damp and agglomerate into granules under normal temperature and humidity. When the iron powder cannot be mixed evenly during the preparation, the iron powder will be baked during the baking process. Organic chemicals such as acetone are not completely volatilized. It will cause the residual chemical substances mixed with granular organic synthetic raw materials to be die-casted into the body of the integrated inductor product.
The surface bulging of the integrated inductor is caused by the volatilization of residual acetone inside. The change of acetone from a solid to a gas will cause a cavity to form inside the inductor, resulting in a change in the inductance value and increased inductance loss. A more serious one will cause a short circuit inside the integrated inductor, which will seriously affect the circuit.
SMD integrated inductors feature one:
1. High current resistance: The high current inductance coil is made of thick copper wire and flat wire, which can withstand high current.
SMD integrated inductors feature two:
2. High stability: The high-current inductor adopts a fully enclosed magnetic shield structure, which has good sealing and high stability.
Three characteristics of chip integrated inductors:
3. Wide application range: high-current chip inductors have good voltage resistance and long-term stability, and can be used on computer motherboards, microcontrollers, graphics cards and other long-working equipment.
