Insulation walls on insulated winding wires are much thinner today than they were in decades past. As the power electronics industry has sought to reduce the size of their components, winding wires have gotten smaller to accommodate the smaller package sizes. The reduction in size was achieved by re…Read More
When designing or selecting a Litz wire for use in a winding, it is important to understand and minimize skin effect and proximity effect losses wherever it is possible to do so. The uneven distribution of current in a Litz wire conductor, due to skin effect and proximity effect losses, increases th…Read More
There are three different test methods used for Electric Strength testing and Breakdown Voltage testing on winding wires. This article will give a brief description of each test method and outline the sizes of winding wires that each test method should be used for. First, however, it would be pruden…Read More
For engineers in the transformer industry who are used to working with solid conductor winding wires, the larger diameters and wider tolerances on Litz wires may come as a bit of a shock. With Litz wires, overall diameters are larger and copper density is lower than on a solid conductor equivalent d…Read More
UL certifications for winding wires can be confusing for those that don’t deal with safety certifications on a regular basis. This article will attempt to clarify what those certifications mean and how winding wires can be used based on those certifications. UL certifications for winding wires can…Read More
For many years, IEC 60950-1 and its UL equivalent, UL 60950-1, have served as the governing safety standards for Information Technology Equipment (ITE), or more simply put, consumer electronics and electronic components. As of December 20th, 2020 though, IEC 60950-1 was replaced by IEC 62368-1 and U…Read More
When designing or selecting an insulated winding wire for use in a wound component, it is important to consider all of the following: What is the range of operating temperatures that the product will see in your application? What temperatures will the wire be subjected to in downstream manufac…Read More
