In this video, Robert Feranec and Thomas Eichstetter demonstrate how to measure and fix EMC problems in a power supply using simple filter design techniques. They cover the setup for EMC measurement, identify causes of EMC issues, and explain how to use RF wallpaper and components like inductors and capacitors. The process includes designing, measuring, and optimizing a filter to improve EMC, with visual examples highlighting differential and common mode effects.
SMD surface mount inductors can be easily mounted by fast pick and place machines and thus reduce its placement cost. The technology also supports high level of miniaturization and downsizing of electronics.
The goal of passive components’ failure analysis (FA) is to determine the root cause for an electrical failure. The findings can be used by the manufacturers to improve upon the design, materials, and processes used to create their components. This leads to better quality and higher reliability components. The FA also provides feedback for the users to improve their handling, storage, and applications of these components.
Würth Elektronik presents WE-HEPC, its smallest NiZn-ferrite-based self-shielded power inductor to date.
Thanks to a new and completely automated manufacturing process, these power inductors provide consistently high quality and higher saturation current than any previous or known competitive product.
In all, there are 15 models available with different attributes (L: 3.3 ~ 100 μH; ISAT: 1.3 ~ 3.3 A) and in package sizes 5030 (4.8 x 4.8 x 1.8 mm) and 6030 (5.9 x 5.9 x 2.85 mm).
Skin losses, also known as skin effect losses, are an important aspect of winding losses in Transformers and Inductors. When the alternating current flows through the wire, it tends to concentrate more on the outer surface due to the skin effect. This results in an underutilization of the inner part of the wire, that leads to energy losses. The current prefers the outer layers of the wire, leaving the inner layers unused.
Inductors, also referred to as coils or sometimes choke, are important passive components along with resistors (R) and capacitors (C). Coils usually refer to wound conductive wires, and among them, those with a single wound wire have in recent years particularly been referred to as inductors.

The automobile has been undergoing a substantial transformation in recent years. With the advent of Advanced Driver Assistance Systems (ADAS), the shift toward electric vehicles, and the growing sophistication of infotainment, cars have evolved to the point where they can be considered advanced electronic devices.
