When designers think of passive components, they think of manufacturing tolerances for inductors and capacitors that are typically ± 20% or ± 10%. That's okay in theory, but not when these components ...

Researchers at the University of Illinois, Urbana-Champaign have devised a method of combining capacitors and inductors in a tiny, 3D rolled membrane. This will save space in the electronic filters ...

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, ...

As the form factor of wireless handsets, PDAs, and other portable electronics continues to shrink while their complexity level continues to grow, design engineers face an increasing number of problems ...

Many manufacturers of passive components focus on addressing the key challenges designers face: cost and board space. A lot of new designs are all about reducing the number of components in the ...

Electronic enthusiasts may be interested in a new versatile RLC-Box created by electronics hobbyist Roger Leifert based in Aachen, Germany. With 3 rotary-switches you can select from 8 decades of ...

Inductors designed with active elements are very desirable to designers today because conventional spiral inductors are too big, too heavy, and too costly, and they require tuning. During the last few ...
