TÜV Rheinland advises Medical Device Manufacturers to Consider New EMC ... - PR Web (press release)

TÜV Rheinland advises Medical Device Manufacturers to Consider New EMC ... - PR Web (press release) | Electromagnetic Compatibility | Scoop.it
Pleasanton, California (PRWEB) January 12, 2015 -- Standard Revision Introduces New Immunity, Risk Analysis Requirements; New Devices Must Comply by April 2017 in the U.S.
Tony Almeida's insight:

4th Edition of IEC 60601-1-2 (requirements and tests for medical equipment and systems): The new revision mandates compliance of new products by April 2017 in the USA and all products by August 2017 in the European Union.

 

Also, according to this text (I have not check this standard yet), it is worth to note that this revision imposes significantly higher EMC test levels.

EDN - Signal distortion from high-K ceramic capacitors | EDN

EDN - Signal distortion from high-K ceramic capacitors | EDN | Electromagnetic Compatibility | Scoop.it
Multilayer ceramic capacitors (MLCCs) are used extensively in modern electronics because they offer high volumetric efficiencies and low equivalent series resistances at attractive prices.
Tony Almeida's insight:

Because this subject concerns about non-ideal behaviour of electronic components - an issue commonly studied in EMC - I decided to publish this article under this topic.
