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 [...]
Making Sense of Current Transformers
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 [...]
Chokes vs. Inductors: What's the Difference?
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.
UL 62368-1: The New Safety Standard for ITE and AV Equipment
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 [...]
The Impact of Chinese New Year on Electronic Component Lead Times
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.
How to Select the Right Transformer Manufacturer
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 [...]
How Does Quality Assurance Impact the Cost of a Transformer?
Many customers believe that the cost of a transformer is limited to the amount that they pay upfront. At a basic level, transformer costs are determined by the time and materials used during the manufacturing process. However, the truth is that transformer costs are impacted by numerous complex factors, particularly when considering the impact on the overall system.
An Introduction to Common Mode Chokes
A choke is a magnetic inductor used to block or limit unwanted high-frequency alternating current (AC) while allowing the desired lower frequency direct current (DC) to pass through. The choke acts as a filter for the noise produced by other radio signaling devices, inverters, and unshielded equipment, thereby reducing interference in electrical and electronic devices and systems.
Food and Beverage Applications for Class 2/3 Power Transformers
Transformers convert alternating current (AC) from one voltage to a higher or lower voltage. Class 2 transformers are safer, more highly-rated electrical components frequently used in the food and beverage industry. Class 2 is a compliance rating signifying that the power transformer meets safety standards that reduce the risks of fire or shock.
Autotransformer Power Transformers
What is an Autotransformer? Autotransformers feature a single winding wound onto a laminated core. They're similar to two-winding transformers, but their differences lie in the ways that the primary and secondary winding are interrelated. There are two varieties of autotransformers which may be differentiated by their construction. In the first type, the transformer relies on continuous winding [...]
