What is the difference between integrated inductor and traditional inductor?

The integral forming inductance consists of a base body and a winding body, which is die-cast by embedding the winding body into the metal magnetic powder. The lead pin of the surface packaging pin is the winding body and is directly formed on the base surface. The integrated inductor is packaged with surface mount and is classified as one of the patch inductors.

Compared with traditional inductors, integrated inductors have the following advantages:

1. Low loss, low impedance, no lead end, small parasitic capacitance. It has a solid and solid structure, closed magnetic circuit, good magnetic shielding and EMI performance.

2. Small size, patch packaging, suitable for automatic assembly of integrated boards.

3. It is suitable for high-power and high-current circuits. It can maintain excellent temperature-rising current and saturation current characteristics in high-frequency environment (working frequency can reach more than 5 MHz) and high-temperature environment.

The only disadvantage is that the workmanship is more complex than traditional inductors, and better inductor production equipment and technology are needed, so the cost of inductor production is higher.

Because the integrated inductor still maintains excellent temperature rise current and saturation current under high temperature and high frequency environment. So it can be used in the fields of digital products, information and communication equipment, automobile and household appliances. The integrated inductor is common with the following products:

1. Tablet computer (PAD), laptop computer, desktop computer, personal game machine. For example, there are many integrated inductors in ADM graphics card.

2. Communication Network Equipment, Vehicle Navigation System

3. DC/DC converter, charging power supply, relay, differential mode filter inductor and so on.
