Determining the utility of an equivalent-circuit model versus construction reality is often a difficult challenge. Using simplified, first-order approximations in models and equivalent circuits is a normal part of engineering life. Without them, we would get mired in the details and harsh reality of the components and their characteristics. We would never be able to […]

How do you make inductors with films, foils, and flat wires?
Wire wound structures are the most common, but far from only, way to make inductors for audio, power conversion, radio frequency (RF), and other applications. Inductors are key components in various circuits, and designers need to fully understand available options. This FAQ starts with a brief background on wirewound inductors and then digs into the […]
Ultraminiature multilayer ceramic chip inductors work up to 10 GHz
AVX Corporation released a new series of ultraminiature multilayer ceramic chip inductors for high-frequency RF applications. The new LCCI Series inductors are currently available in three standard EIA chip sizes — 0201, 0402, and 0603 — with tight-tolerance physical dimensions almost exclusively in the submillimeter range and tin-plated surface-mount terminations, enabling compatibility with high-density PCBs […]
Chip inductors designed for automotive audio bus apps
Bourns, Inc. announced its new 1210-size automotive-grade common-mode chip inductor series. Bourns’ latest family of common-mode inductors are designed with a ferrite core and are bifilar-wound to deliver a compact size and shielded construction. The Model SRF3225AB and SRF3225TAC common-mode chip inductor series offer low radiation and high impedance over a broad frequency range to suppress Electromagnetic […]
SMD ceramic inductors feature high Q, high thermal stability
Würth Elektronik has expanded its WE-KI product family with further ceramic inductor variants in 0603 and 0805 packages. Now the portfolio includes over 300 models in four sizes from 0402 to 1008, optionally with ±2 and ±5 percent tolerance. With the new range of models, the available inductance values cover 1 to 1800 nH. The […]
