One-piece inductors are also called: Molded inductors include magnets and windings themselves. Surface-mount inductors. The key difference from general output power control inductors depends on the fact that one-piece inductors have a winding first, and then The metal is formed by die-casting of powdered and filled aluminum with magnetic material, and the leads are drawn out from the side and then bent back to form. The integrally molded inductor (inductor molding) has the same size, and the same inductor can reduce noise compared to other types of inductor current, with a smaller DC resistance characteristic, and higher reliability and similarity. Things. The key technology is applied to a variety of different types of power filter circuits, especially the application of the CPU power supply part. Because the integrated inductor has relatively high reliability of mechanical equipment, it is often used in the electronic equipment of the automobile manufacturing industry. in.
One-piece inductor
As the main frequency of the CPU of the electronic computer and the running memory of the smart phone are getting higher and higher, there are very high regulations for the stable power supply system and filtering. The emergence of one-piece inductors has just solved this problem. It can work for a long time under the standard of large current and provide a stable power supply for the CPU. In these aspects, the performance of the one-piece inductor is very good. The excellent raw material characteristics and unique design scheme make the inductor structure more stable, lower resistance, excellent seismic characteristics, and have a very high conversion efficiency. As the volume of my country’s electronic information commodities is getting smaller and smaller, the output power requirements are getting larger and larger, and the components of electronic products are also developing towards the level of small size and high power.
Compared with traditional inductors, integrated inductors have the following advantages:
1. Fully enclosed magnetic shielding structure, the equivalent circuit is closed, the anti-interference signal is strong, and the transformer core is inseparable from the winding, so it can also prevent noise and can be installed in high-density buildings.
2. Use low-loss alloy powder die-casting, low characteristic impedance and high compressive strength.
3. The one-piece structure is firm and firm, the product has high precision, and it is durable and does not rust.
4. It has a small volume and a large current capacity. It can maintain a high-quality temperature rise current and saturated operating current development characteristics at high temperatures.
5. The raw materials of the integrated inductor are imported raw materials, and the quality is more meticulous.
6. The one-piece inductor has higher inductance and smaller leakage inductance, and its service life is longer than that of general inductors.
- One-piece inductors are mostly used in discrete graphics cards, tablets, notebooks, automotive equipment, DC/DC converters, communication equipment, and are suitable for automotive, military, medical, aerospace and other fields with high reliability regulations.
