Power Adapter Basic Component Selection

Power adapter | Basic Component Selection Guide

Although the appearance of the power adapter looks not big, but the internal structure is also quite complex, an ordinary 5V/1A power adapter, the internal also include filter capacitors, transformers, varistors and other nearly a dozen kinds of components.

These large and small components can be said to be a variety of power adapter "organs", these "organs" of good and bad will affect the overall function of the power adapter to play. So as a power adapter manufacturer, we will follow the basic principles when purchasing these components?

The principle of universality: the selected components should be widely used and verified, as little as possible, the use of cold, remote chip, to reduce the risk of development.

Cost-effective principle: in the function, performance, utilization rate are similar, try to choose the better price components, reduce costs.

The principle of easy procurement: try to choose components that are easy to buy and have a short supply cycle.

The principle of sustainable development: try to choose components that will not be discontinued in the foreseeable time.

Substitutable principle: try to choose pin to pin compatible chip brand more components.

Principle of upward compatibility: Try to choose components that have been used in old products before.

The principle of resource conservation: try to use all the functions and pins of the components.

The process of chip selection is a compromise between various dimensions.

Assembly

In the selection process, we also need to consider the situation of trial production, and at the same time, we need to consider the situation of mass production. The price of small purchases, supply cycle, sample application; at the same time need to pay attention to, after the price of large quantities and supply cycle. It is possible that after the batch becomes large, the supply price is not advantageous, or after the batch is large, insufficient capacity. In addition, according to their actual procurement, to find the corresponding volume of suppliers. For example, the original factory is often not direct supply, you need to go through an agent. Some agents are required to supply the volume level.

After years of hard work, Eahunt Technology has already had a certain influence in the industry of power adapters. Because of good reputation, strong strength, and purchasing volume is relatively large, Eahunt has a number of very reliable supplier partners. The stable and high-quality supply chain provides Eahunt with all kinds of raw materials needed for production in a timely manner. This guarantees our delivery time and the high quality of Eahunt's power adapters.
