EMC spring contacts or fingerstock are originally made of copper-beryllium (CuBe2) due to its unique combination of high electrical conductivity, excellent spring properties, and mechanical strength. This made it the gold standard for EMI/RFI shielding in demanding applications such as aerospace, defense, and telecommunications. However, copper-beryllium can be toxic during processing and may pose health…
DetailsThe new series of Oval-Snap-It and Oval-Clip-It ferrite cores from Fair-Rite offer several advantages over the conventional round variants. The oval geometry is an ideal solution for common-mode chokes, where two cables can be routed side by side to suppress the generated interference signals from motor drives, power supplies, and other applications. This oval design…
DetailsIn high-tech electronics such as aerospace, defense, telecommunications, and the semiconductor industry, a reliable EMC seal is essential. Parker Chomerics is a global leader in the development of thermal interface and electrically conductive compounds, including high-quality Form-in-Place (FIP) seals or gaskets. These so-called seals or beads are often applied automatically using a robot dispenser, with…
DetailsMagnetic field shielding is critical for the reliable operation of quantum computers. Traditionally, mu-metal is used for this purpose, but this material is not suitable for the extremely low temperatures in which quantum computers operate. Magnetic Shields has developed Cryophy: a special soft magnetic nickel-iron alloy that provides optimal magnetic shielding in cryogenic environments at…
DetailsParker Chomerics has developed the advanced thermal gap filler, THERM-A-GAP PAD 80LO, specifically for durable, mission-critical, and high-power electronic applications in sectors such as high-performance computing, defense, telecommunications, and automotive. With a high thermal conductivity of 8.0 W/m·K and exceptionally low silicone oil loss, PAD 80LO provides a sustainable, reliable solution for environments where traditional…
DetailsInconel, an extremely strong and corrosion-resistant nickel-chromium superalloy, opens up new possibilities for EMC shielding of ventilation openings through 3D printing technology. Traditional honeycomb filters are often vulnerable to mechanical damage, but with additive manufacturing, these limitations are a thing of the past. Thanks to 3D printing, Parker Chomerics can create robust, complex geometries without…
DetailsThe military-grade HEMP filters from EMI Solutions provide protection against electromagnetic interference (EMI) caused by HEMP (High-altitude Electromagnetic Pulse) or HPM (High Power Microwave). These high-power voltage pulses can cause significant damage to systems built with standard components, such as communication equipment, PCs, servers, and peripheral devices. The use of HEMP filters is essential in…
DetailsThe Terahertz Sensing group at TU Delft conducts research in applied electromagnetics, antennas, optics, and sensors for space applications. To prevent unwanted reflections of these high-frequency signals, absorber materials are used. While other absorber materials are typically specified up to a maximum of 60 GHz, ABS material has been verified and tested up to 220…
DetailsParker Chomerics THERM-A-GAP GEL 50VT is a reusable, silicone thermal interface gel with a thermal conductivity of 5.2 W/m-K. This material is specifically designed to transfer heat from electronics to heat sinks or enclosures. The designation “VT” stands for vertical tack and indicates reliable performance in both vertical applications and vibration-intensive environments. During its development,…
DetailsThe upgraded PAM-0207A preamplifier from AH Systems is the ideal choice for enhancing the dynamic range of a test system. This preamplifier boosts sensitivity by at least 25 dB without compromising frequency-related gain. Whether performing measurements in an EMC lab or conducting general RFI tests in the field, the PAM-0207A offers a robust and compact…
