How to Choose Small Transformer for PCB

Transformer is an important electronic component. Nowadays, small transformers are widely used on PCB, which brings great convenience to people’s production. However, it is difficult for people with no previous transformer experience to purchase the right transformer smoothly and practically. Now, let’s talk about how to choose small transformer for PCB

Advantages of High Frequency Transformers

11 Advantages of High Frequency Transformers
1. Small size: A ferrite material high-frequency transformer has the advantages of high conversion efficiency and small size.
2.Low cost: Since the amount of silicon steel sheet and copper wire used in the transformer is related to the rated induced potential and current of the winding, the winding capacity is lower, and materials are also used less and the cost is lower.
3.More efficient:Due to the reduced copper and silicon steel wires and sheets, at the same magnetic flux density and current density, the copper and iron losses are reduced compared with the double-winding transformer, so the efficiency is higher.

What are the application of inductors?

The inductor is a passive component,it can convert electrical energy into magnetic energy and store it. An inductor is similar in structure to a transformer, but it has only one winding. Inductors have inductances, but they only inhibit the progress of current. If the inductor is in a state where no current flows, it will try to block current from flowing through it when the circuit is turned on. If the inductor is in a state where current is flowing, it will try to maintain the current when the circuit is disconnected. Inductors are also called chokes, reactors, dynamic reactors.

What is a PCB Mount Transformer?

The PCB Mount Transformer is a transformer specially designed for printed circuit boards and is located on the surface of the circuit board to provide any voltage or current conversion functions that may be required. These devices have a variety of different properties and sizes, ensuring that their variety can be selected for any imaginable product. The transformer used in the PCB must be compact, and because of this, the transformer does not have a complicated cooling mechanism, which sometimes has to be incorporated into other transformer designs. The transformer used for the printed circuit board must be compact, so the transformer does not have a complicated cooling mechanism. If you need a cooling mechanism, use another transformer design.

What is a Step Down Transformer

With a step down transformer, high voltage power from the power grid is reduced to low voltage for various electrical equipment to meet their needs. The step down transformer is a transformer that reduces the output voltage and converts the higher voltage at the input into a lower output voltage. In other words, it can convert a low current high voltage to a high-current low voltage, which is the purpose of a step down transformer.

What is a step up transforme?

A step-up transformer is a transformer used to change a low-voltage alternating current into a higher voltage alternating current with the same frequency, which is secondary current is higher than the primary voltage. In other words, there are more secondary winding than primary winding. For example, if you want to use a 220V device in some place with 110V electricity, you need a step-up transform.
