All electrical devices produce heat as an operational byproduct. In transformers, normal operation causes an internal temperature increase or temperature rise. When the transformer is at its nameplate rating, the transformer temperature rise is the average temperature increase of the windings above the ambient temperature. This increase in temperature has the potential to shorten the [...]
Power inductors can be used to filter the current or convert the Voltage and current to a different Voltage and current. Applications range from small electrical appliances to large power grid systems. Inductors consist of wound conductive metal coils that generate a magnetic field when electricity flows through them. Inductors are essential in any application that needs to carefully control [...]
Current transformers (CTs)—also known as current sense transformers or current sensors—are instruments that are designed and manufactured to detect electrical currents and convert them into more usable forms for different applications. They perform these detections and conversions by measuring the larger current value in the primary winding and developing a corresponding smaller current in the [...]
Numerous technologies rely on chokes or inductors to deliver, alter, and filter electrical current. Understanding the difference between chokes and inductors is essential when designing devices and machinery that rely on electrical power. These electrical components each suit specific applications.

In December 2020, product safety standards based on IEC 62368-1 will be superseding IEC 60950 and 60065 across the world, including Underwriters Laboratories (UL) in the US. The goal of the new standard is to establish a more universal and clear approach to hazard-based product testing. It replaces two previous standards—60065 for audio/visual (AV) equipment and 60950-1 for information [...]

UL is dedicated to the development of more secure and sustainable products [...]
In China, one of the most important national events is the Spring Festival. This annual event—also often referred to as Chinese New Year—falls somewhere between the end of January and the middle of February. In 2021, it is set to begin on February 12th.
At their most basic level, transformers consist of a primary and secondary winding situated around a magnetic core. Audio transformers are used to transmit sound signals from the primary to secondary winding with high accuracy and minimal distortion. Transformers are the most effective solution in many audio applications as they allow for electrical energy to be transferred from one circuit to [...]
When sourcing a standard or custom transformer, it is essential to choose a quality manufacturer to ensure the product functions as intended. However, given the large number of potential options available, selecting the right one can be challenging. In the following blog post, we provide an overview of some of the key factors to consider when vetting transformer manufacturers to help you choose [...]
