EMI enclosure features inflatable frame for RF shielding effectiveness
Saelig Company, Inc. has introduced the Select Fabricators Series 700 EMI Enclosures – reliable, portable, and lightweight RF and EMI shielding enclosures in standard sizes with a fast-up inflatable frame, ready for operation in less than 60 seconds. For some customers, a rapid deployment of EMI enclosures is critical. While aluminum frame tents can deploy in […]
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 […]
Catalog update covers passive components, optoelectronics and power modules
With “Electronic Components 2020/2021” Würth Elektronik publishes an updated supplement to its general catalog. Besides a series of innovative new products, there is background and basic knowledge about EMC for high-frequency applications, gate driver circuits, single pair Ethernet, laser and infrared LEDs, as well as additional information. Practical application examples support the use of the […]
Soon, Air Pollution Could Be Measured on Every Street Corner
Air pollution is responsible for 550,000 premature deaths a year in Europe and 7 million worldwide, according to the WHO. Measuring it can be a challenge, however, as the equipment tends to be large and expensive. But soon, this may change, thanks to a small, optical nanosensor developed at Chalmers University of Technology, Sweden, which […]
