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.

What Exactly Is the Difference Between IP66 and IP67?

  What is IP67 and what is the difference between it and IP66?   This is probably the question that JRPanel engineers have been asked most often recently.   On the  online pricing page  of JRPanel's website, a new option appears in the Rear Adhesive section: 3M300LSE & Waterproof ( IP67 ).   In fact, this is a waterproof process recently upgraded by the JRPanel factory. This process can bring more possibilities to your products, and it also marks that JRPanel's products have reached a new level.   So what is the difference between IP67 and the previous  IP66 process ? In this article, we will explain in detail.   In the previous article  Criteria for the Classification Ratings of Ingress Protection , we introduced that the ingress protection rating is composed of two digits. The first  digit  represents the level of the electrical appliance's ability to prevent intrusion of foreign objects, and the second  digit ...

Brief Introduction to Flat Spiral Coil Inductors

  Hi guys! Today JRPanel would like to share a few points about Flat Spiral Coil  Inductors  with you. Basically, a flat coil inductor is an inductor wound with flat copper wire.  The picture below is the side view, we can see that each circle of copper wire is arranged very compact. Here are some of the application characteristics of flat coils : 1.  High current inductance 2.  Lowest DC resistance           3.  Can ensure smooth drop of current-resistant inductance 4.  Suitable for reflow SMT process 5.  Lead-free, RoHS compliant This pciture shows a flat coil product.  It is generally used in power supplies, personal computers and other handheld  electronic devices . Advantages of  F lat  C oil  I nductors are : 1.  Scientific and reasonable space design. 2.  Tight and flat between turns ensures the effective cross-sectional area of the wire, which greatly reduces the copper loss ...

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 transf...
