Electrodes and terminations are fundamental to the construction of passive electronic components, with emphasis upon stacked ceramic solutions for capacitance, resistance, inductance and sensing in electronic circuits. Older legacy materials for electrodes and terminations include palladium and silver respectively. These electrodes and terminations are still consumed in low layer count ceramic components or in specialty chip thermistors and varistors, inductors and resistors.

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 and Proximity Losses as Key Impact Factors of Transformer and Inductor Winding Losses

  • Posted by doEEEt Media Group
  • On July 7, 2023
  • 0
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.
