LISN, ready for practical measurements

A Line Impedance Stabilization Network or LISN is a test device that measures disturbances that are generated by a connected electrical device and which are passed on via cabling. These high-frequency disturbances pollute the mains; other devices may be disrupted or even get damaged. Most LISNs are only made to measure according to the standard.…

Adhesives: the alternative to (hard) soldering

CHO-BOND 584-208 is a two-component, silver-filled, electrically conductive epoxy adhesive, which can be used to replace soldered or welded joints under certain conditions. It has been developed for use in high volume applications where a strong, long lasting and low ohmic electrically conductive adhesive bond is required. The typical resistance is 0.002 ohm-cm and the…

EMI source for CISPR and FCC pre-compliance testing

Com-Power model CGO-501 Comb Generator is a broadband EMC signal source for a fast EMC test. It generates a signal up to 1000MHz in 1MHz steps EMC labs regularly calibrate their instrumentation, accessories and test sites for radiated emissions. These procedures are extensive and time consuming. However, calibration does not prevent equipment from malfunctioning between…

First USB 3.2 feed-thru filter with 20 Gbps / 100W

Meet the brand new innovative Ranatec RI 4199 USB 3.2 feed-thru filter. The panel-mountable filter has USB-C connectors on both sides and is bi-directional.

Thermally conductive graphite for best heat dissipation

Leadertech produces thermal interface material in sheets, also based on graphite. Graphite is used for its extremely good thermal conductivity, but only on surfaces that don’t need to be electrically isolated. The vertical conductivity is a decent 5W/m-K while the horizontal thermal conductivity is extremely high at 400W/m-K. Therefore, thermally conductive graphite can be used…

Practical Power Analyzer for inverters and power supplies

With the Power Analyzer DPA3011, Elab-Tools offers a practical and universal measuring instrument for electronics engineers who develop equipment that is connected to the mains, such as inverters, machines and power supplies. The Power Analyzer is used to measure the power factor, harmonics and distortion during dynamic current behavior. The DPA3011 records 8 signal parameters:…

Lightweight Flexible EMC Test Lab

The Shieldex EMI tents are made of self-produced yarns and textiles. This base material can be optimized to the desired radiation attenuation and frequency range. A tent is made up of several layers for the best measurement result, but also to guarantee functionality and thus create a robust, tear-resistant and practical workable solution. With these…

Handheld ESD simulator

Electronic equipment must have a certain immunity to electrostatic discharge, tested according to the international standard IEC 61000-4-2. The German equipment manufacturer Schlöder has a series of programmable ESD simulators guns, which can be used both on battery and mains: SESD 216: 16.5kV air and 10kV contact discharge SESD 230: 30kV air and contact discharge…

EMC shielding for medical displays

Display filters for medical devices have challenging characteristics, including EMC shielding, chemical resistance, as well as maximum readability. PSC has various solutions for this. Polycarbonate with indium-tin oxide coating: robust solution, small color difference possible, almost no noticeable loss in transparency Optical-grade acrylic with a cast steel or copper mesh: best optical properties, highest EMC…
