Different Types of Tape Used in High Frequency Transformer

 Hi guys, glad to see you here again! In previous JRPanel videos, you must have found that the high frequency transformer is always wapped in yellow tape.

 

In this blog, JRPanel would like to introduce you the different types of tape used in High Frequency Transformer.


1. Mara Tape

 

Mara tape, also known as polyester tape, uses polyester film as the base material and the adhesive is acrylic flame retardant adhesive.




This kind of tape has excellent resistance to chemicals and moisture, and can resist cuts and abrasions. Because of its flame retardant and insulating characteristics, mara tape is often used as insulation between windings of high and low frequency transformers and as a core fixing material for transformers.


There are many colors of Mara Tape, usually red, blue, yellow, white, etc. It has certain elasticity and stretchability, and one side is coated with adhesive.




It is widely used in transformers, motors, capacitors and other types of electronic components for insulation wrapping, and can also be used for high-voltage isolation in the switching power supply.

 

2. Margin Tape

 

Margin tape, also known as non-woven tape, is made by bonding a non-woven fabric to a polyester film substrate and coating one side of the non-woven fabric with an acrylic adhesive with excellent performance.

 



Margin tape is mainly used for insulation of uninterruptible power supplies, dry-type transformers, high temperature industrial frequency transformers, high temperature gaskets and microwave oven transformers.

 

3. Polyimide Tape

 

Polyimide tape, which is based on polyimide film with imported silicone pressure-sensitive adhesive, is resistant to high and low temperatures, acids and alkalis, solvents, electrical insulation (class H), and radiation.

 



In the electronic and electrical industry, it can be used for H-class motor and transformer coil insulation wrapping, high temperature resistant coil end fixing, temperature measuring RTD protection, capacitor and wire wrapping and other bonding insulation under high temperature working conditions.


In the circuit board manufacturing industry, it can be used for electronic protection paste, especially for SMT temperature resistance protection, PCB gold finger protection, electronic transformers and other high temperature and moisture protection.

 

4. Copper Foil Tape


Copper foil tape, a metal tape, is mainly used for electromagnetic shielding applications.

 



It has strong adhesion and good electrical conductivity, and can be easily wrapped and attached to the wire, and can be cut to various specifications according to customer requirements.


Its purity is higher than 99.95%, eliminating electromagnetic interference (EMI), isolating the harm of electromagnetic waves to human body, and avoiding unwanted voltage and current.


In addition, this type of tape has a good effect for static discharge after grounding. It is generally applied to transformers, cell phones, computers, PDAs, PDPs, LED screens and other various electronic products where electromagnetic shielding is required.

Identify Different Types of Transformer Cores, Based on Materials

  Hi guys, this is JRPanel ! In previous  blog s, we have introduced several points about High Frequency Transformer, like  bobbins  and  Flat Spiral Coil . In this blog, JRPanel would like to introduce the commonly used magnetic cores in transformers ,  based on materials.   Generally speaking, the material of the core determines the environment in which the transformer is used. A transformer that uses a core of a different material will have its performance affected, may even be non-functional.   By material, magnetic cores are generally divided into the  several  categories . JRPanel will introduce them one by one to help you understand more fully.   1. Manganese Zinc Ferrite Core Mn-Zn core is a soft magnetic core with high initial permeability (2000~15000). The higher the initial permeability, the lower the surface resistance, so it is generally used in circuits below 1 MHz. Mn-Zn core has a high saturation flux density and causes lower losses, making it one of the most desirable

The Relationship Between Plastic Nameplates and Membrane Switches

Before the 1970s, most nameplates   were made of metal materials. Today, plastic  nameplates   have been widely used in household appliances, instruments, meters, office equipment and other fields, and have become an indispensable part of electromechanical products. It not only plays the role of trademark identification, specification model, function indication, etc., but also becomes an element that reflects the appearance of the product.   With the continuous use of new materials and new processes, the surface of plastic  nameplates   is constantly improving, and it has become the crystallization of three major technologies: comprehensive surface treatment, processing and molding, and screen printing.   Plastic  nameplates   can be divided into 2 types according to their material processing methods and objects of use:   1. The injection-type plastic  nameplate   is made of ABS, PC and other engineering injection molding, and then undergoes secondary surface decoration processing such

The Main Use and Classification Methods of Transformer Bobbins

  Hi guys, this blog is still about   high frequency transformers .   JRPanel   would like to introduce you the main use of transformer bobbins and how we classify them.   In the pictures are the transformer bobbins.        Following are the main uses of that JRPanel has summarized for you:   1. The bobbins provide space for winding copper wires in transformers.   2. Wire channel in the bobbins provides path for transformer winding.   3. The bobbins help to fix the core in the transformers.   4. The metal pins in the bobbins are connected to the  PCB  after soldering, which play an important role in conducting electricity when the transformer is working.   5. The baffle at the bottom of the bobbins isolates the core from the tin stack to avoid poor volta ge resistance.       From this it can be seen that the importance of bobbins in transformer is extraordinary.   After understanding the main uses of transformer bobbins,  JRPanel  is to introduce its common classification methods.   Fi
