Introduction Lightning may produce a spectacular display when viewed, but the associated electromagnetic effects (EME) has the potential (pun intended) to severely damage electrical and electronic circuits. MIL-STD-461G added a new test method to evaluate device tolerance for induced current on equipment cables or insulation breakdown from the effects of indirect lightning. … [Read more...]
EMC Laboratory Selection Audit Items
Introduction This blog will provide the reader with an introduction to some of the items that need to be looked at when auditing an EMC laboratory with an eye to placing them on your company’s approved lab list. This is not an in-depth look at each item but is based on my experiences auditing laboratories (both in-house and 3rd party) over a number of years. Key … [Read more...]
The Top-Ten Articles and Blogs as of December 2018
Most magazines like to review the top ten most viewed articles this time of year and Interference Technology is no different. We think our readers and authors are awesome and enjoy highlighting some of the most popular articles to date. So, here we go: What is differential and common mode current, by Ron Brewer. Unwanted conductive and radiative emissions can be … [Read more...]
Combiner IP-EMC seal
Gaskets made out of conductive rubber are quite expensive and are also usually less soft than needed for the application. Due to excessive stiffness, the door or lid of the electronics housing will become warped or bent, which then causes electromagnetic leakage. Therefore we have developed gaskets which provide the same functionality while being significantly softer. Gasket … [Read more...]
New Solid State Amplifier, 100 Watt CW, 4 kHz – 400 MHz for BCI Testing
The Model 100A400AM20 is a solid-state, self -contained, air-cooled, broadband amplifier designed for applications requiring RF power down to 4kHz, such as MIL STD 461 and the CS114 test standard along with any application where instantaneous bandwidth, high gain, and linearity are required. Available in a stylish, contemporary cabinet for benchtop use or with cabinet removed … [Read more...]
New Class A Amplifier Design, 600 Watt CW, 10 kHz – 400 MHz
The Model 600A400 is a solid-state, self-contained, air-cooled, broadband amplifier designed for applications where instantaneous bandwidth, high gain and linearity are required. Available in a stylish, contemporary cabinet for benchtop use or with cabinet removed for rack mounting. The Model 600A400, when used with a sweep generator, will provide a minimum of 600 watts of … [Read more...]
Film capacitors: Series of rugged AC filter capacitors extended
TDK Corporation (TSE:6762) has extended its EPCOS B32754* to B32758* series of AC filter capacitors. They now cover a range of voltages from 250 V AC to 400 V AC and offer capacitances of between 1 µF and 70 µF. The capacitors comply with IEC 61071: 2007 and are extremely robust, even at high humidity. This has been verified in a temperature, humidity, bias (THB) test at 60 °C, … [Read more...]
TVS diodes with low terminal voltage from Würth Elektronik eiSos
Three product series for safe protection against ESD Waldenburg (Germany), 19 October 2018 – Würth Elektronik eiSos has expanded its portfolio of TVS diodes. The diodes are characterized by their short response time and an extremely low terminal voltage, and feature a high ESD dielectric strength with a contact discharge of up to ±30 kV. WE-TVS diodes in the three … [Read more...]
Review of MIL-STD-461 CS118 – Electrostatic Discharge
Introduction MIL-STD-461G, released in December 2015, added a test for Personnel Borne Electrostatic Discharge (ESD). Prior to this release, this type of test for electronic systems and sub-systems was managed at the system level under MIL-STD-464C released in 2010. Both of these standards contain similar requirements. MIL-STD-461G provides the details on testing and … [Read more...]
