Vacuum potting fix the lamination steel and bobbin, and at the same time, ensure that the transformer will not corrode when placed in the air for a long time. It is perfect for applications in harsh environments, where dust, lint, moisture and corrosive contaminants can accumulate.

Since traditional transformers can’t meet today’s efficiency requirements, high-frequency transformers were invented. High-frequency transformers improve efficiency, as well as save power, and have a longer service life than standard transformers.

The basic principles of step-up transformer and step-down transformer are the same.The main difference between a step-up transformer and a step-down transformer is their performance during their operation. The step-up transformer is designed to increase the output value, while the step-down transformer is designed to decrease it. Here, we discuss the differences between step-up transformers and step-down transformers, including definition, voltage，windings, conductor sizes, magnetic fields, and applications.

Learn Unicreed which types transformers could be used in PCB board, such as the following:
1. 50/60Hz Encapsulated Transformer (0.35VA-24V)
2. Toroidal Transformer (15VA-3000VA)
3. Open frame/Linear Transformer (1.1VA-600VA)
4. High Frequency Transformer
5. Common Mode Choke(1.5W-35W)
6. Coils

17 core types used for high frequency transformer
There are many types of high-frequency transformer cores. Below are 17 core types that are most commonly used in high-frequency transformers,I hope that this information will be helpful.

You must first determine the size of the power transformer to be designed, and then calculate the core AE area by using a formula or experience, and finally determine the type of core.
It is important to know the position of the transformer in the pcb, otherwise the designed transformer is too large for the PCB, and the power is too low to meet the requirements.

Here are some high frequency transformer applications:
1.Voltage test equipment
2.Mobile phone charger
3.Switching power supply
4.Lighting equipment
5.X-ray equipment
6.Communication system
7.Industrial robots
8.Photography technology equipment
9.Medical equipment
10.Laboratory equipment

Unicreed is a professional PCB transformers manufacturer in China, we mainly focus on developing and producting 4 kinds of PCB transformer: Encapsulated Transformer, Open Frame/Linear Transformer, Toroidal Transformer and High Frequency Transformer. The following are our inspection contents and requirements for our 4 kinds of PCB transformers.

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

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.
