Noise and other electromagnetic interference (EMI) can pass through electronic equipment as a result of coupling, conductively, via the equipment wires. When this noise occurs on a single line, it adds to the carried signal and is referred to as differential mode noise.

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 [...]

Transformers are passive electrical devices that use magnetic induction to step up or step down incoming AC power voltage to match the voltage needed for the user’s electronic device. They are organized into classifications based on capability and performance level. Class 2 transformers are used for low-voltage circuit control, while Class 3 transformers are used in mid-voltage control [...]

What Is An Audio Transformer? Audio transformers are electronic devices that transmit frequencies within the audio band. They are used in audio amplifier circuits to:

IATF 16949:2016 is a quality management system specifically designed for the automotive industry. The International Automotive Task Force (IATF) is an “ad hoc” group of automotive manufacturers and their respective National Automotive Industry Associations, formed to provide improved quality requirements for automotive products worldwide. This IATF standard is based on the ISO 9001 standard but [...]

It's no secret the medical industry is full of regulations to keep patients and practitioners safe. However, many may not know that additional regulations are required for electrical transformers used in medical devices. These transformers are specifically designed to protect workers and patients.

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 [...]

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 technology [...]

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.
