An inductor's apparent inductance varies with the measurement method and frequency. William Hays, BH Electronics, Inc., Marshall, Minn. Inductors range from RF coils used in communications through ...

Inductors and transformers serve key roles in switch-mode power supplies. Ensuring they perform as expected requires thorough in-circuit measurements performed under operating conditions. Here’s what ...

If you are a novice electronic constructor, you will become familiar with common electronic components. Resistors, capacitors, transistors, diodes, LEDs, integrated circuits. These are the fodder for ...

Boca Raton, Fla. — The Coiltronics high-current HC9 surface-mount inductors from Cooper Bussmann Electronics Technologies, a business unit of Cooper Bussmann, are designed for VRM (multi-phase buck ...

ALPS Green Devices has developed the “GLCLK Series” and “GLCLM Series” Liqualloy Power Inductors, suitable for power supply circuits of displays for smartphones and other compact mobile devices, such ...

In new energy applications, power conversion devices (such as inverters, converters, DC-DC converters, etc.) need to handle ...

TDK has created a SMD inductor particularly for the bias-tee (bias-T) circuits used to split RF signals and dc power from, or combine them onto, a single line. “The component achieves an inductance of ...

Inductance is the link between electric circuits and magnetic fields. Voltage and current sine waves are in-phase when they peak and cross the zero axis at the same time. However, this rarely happens ...

Over the past century, electronic engineering has improved massively. In the 1920s, a state-of-the-art AM radio contained several vacuum tubes, a few enormous inductors, capacitors and resistors, ...
