Swapfest: The 2023 season opener
Cambridge, Mass. — On a cold, wet, windy day about two weeks after baseball season opened, the 2023 Swapfest: The Flea at MIT season opened. Ocurring on the third Sunday morning of the month through October, the swapfest isn’t so much for swapping, but more for buying and selling. While I didn’t buy anything on […]
CES roundup: Products for engineers
From capacitors to test equipment, engineers can find components that consumers don’t even know are inside their gadgets.
Website, app, let engineers download and import part models
SnapEDA gives engineers free access to 3D models and footprints for PCB design. Designing a PCB is hard work. You have mechanical, electrical, and thermal considerations, any of which can make or break a design. You must design your board to accommodate the footprint and packaging of every part. Obtaining the data means you must […]
From resistors to antique radios, swapfests have it all
The effect of DC bias on MLCC class 2 capacitors
Not all capacitors are created equal. Some are polarized, some are ultra-stable, and others have low dielectric absorption or high volumetric efficiency—all depending on the materials and other physical characteristics in the technologies used in manufacturing. Multiayer ceramic capacitors (MLCC) are divided into types or classes, based on the materials used for the dielectric. These […]
Compact flat-wire SMT chokes carry high currents
TDK Corporation has extended its portfolio of EPCOS ERU SMT power inductors with the ERU16 choke series, comprised of ten different types. The inductance values of the new B82559B*A016 series, which replaces the former B82559AA016 series, extend from 1.0 µH to 30 µH, and their saturation currents range from 10.3 A DC to 40.4 A […]
