Interference Technology

There are many kinds of risk For example: the risk of being late for an appointment; the risk of buying a lottery ticket but  not winning a prize; the risk of designing and manufacturing a new product that might not […]

I recently published this blog, detailing a simple proven method for estimating the radiated E field with  specified test setup. As a result, I received the following feedback… ‘This model is wrong for equipment tested over a ground plane as described. The […]

A simple method for estimating radiated emissions I recently received the following question: How to calculate the radiated E field with following test conditions with an antenna placed 1 meter away from the test setup?: A commercial equipment under test […]

In Part 2 of this blog, the harmonic current distortion of a typical Variable Frequency Drive (VFD) is discussed, as well the possible solutions to the problems that this causes. Active Front End or (AFE) units are also discussed and […]

AC variable frequency drives (VFDs) have been in existence in a number of forms since the early 1970s. In the early 1980s the “pulse width modulated” (PMW) VFD versions began to appear. This form of motor control produced less motor […]

Background  Filters are almost always a part of electronics design. Design engineers design a filter to achieve certain attenuation in specified frequency range. There are many types of filters, such as high pass, low pass or bandwidth. Popular filter configurations […]

Enhanced single-line and new triple- and quadruple-line filters expand clean data transmission options, reduce wall penetrations, and improve mounting security and terminal block connectivity. Elmsford, NY – ITG Electronics, a leading manufacturer of inductors, transformers and EMI Filters since 1963, […]

This article is intended to provide an understanding of the requirements for qualification of an Absorber Lined Shielded Enclosure (ALSE) for use in the measurement of radiated disturbances in the frequency range of 150 kHz to 2,500 MHz, as described […]

The demand for wireless medical applications such as remote patient monitoring, real-time diagnostic analysis, smart surgical systems, and implantable sensors have grown significantly over the last couple of years. Thanks to implanted medical devices, many patients live an almost normal […]

Heilind Electronics, a premier global distributor of electronic components, has expanded its connector portfolio with the addition of Quell Corporation – a subsidiary of HEICO and a leading manufacturer of EMI/RFI and transient protection solutions. The distribution agreement includes both […]
