Prem Magnetics Inc. recently
introduced several series of common-mode chokes for reducing unwanted
common-mode noise signals on a power line.
Comprising a total of 128 parts utilizing seven
different mounting packages, the SPCM series covers inductance values ranging
from 65.0uHy to 120mHy and current values ranging from 0.3ADC to 30Arms.
All of these common mode chokes utilize toroidal
core construction that offers a small size and reduced EMI. Mounting styles are
printed circuit board mount incorporating either through-hole or surface mount
Component orientation is configured for reduced
height or reduced board real estate. Many of these chokes incorporate a winding
separation spacer that provides 1 - 3 mm creepage distance for safety agency
compliance, and all units use UL94V0 materials.
Pricing ranges from $1.39 to $5.67 in production
Last year at Hannover Fair, lots of people were talking about Industry 4.0. This is a concept that seems to have a different name in every region. I’ve been referring to it as the Industrial Internet of Things (IIoT), not to be confused with the plain old Internet of Things (IoT). Others refer to it as the Connected Industry, the smart factory concept, M2M, data extraction, and so on.
Some of the biggest self-assembled building blocks and structures made from engineered DNA have been developed by researchers at Harvard's Wyss Institute. The largest, a hexagonal prism, is one-tenth the size of an average bacterium.
