Competitively priced thermal interface material

Parker Chomerics introduces the PAD60, a new thermal interface material that is very competitive in both price and performance. With a specified thermal conductivity of 6W/m-K, this fairly soft gap filler is an extremely effective solution between a heat sink and an electronic component. The competitive price, positions the PAD60 in consumer electronics, LED applications,…

RFID signal absorber

With the TLF material ABS Technics has developed a multi-layer RFID absorber plate for UHF applications, which minimizes or even completely avoids “false positive” recognitions. A typical application is in RFID recognition tunnels and truck docking stations. Unwanted RFID reflections sometimes arise there, for example through the steel construction of the building or adjacent RFID…

Perfect EMC shielding and grounding with mesh gaskets

Leadertech mesh gaskets are knitted fine mesh metal mesh gaskets that are used to provide EMI protection. This means that component transitions and connections must be electrically coupled to the chassis. The most common wire materials: Monel, a nickel-copper alloy: Most commonly used, it offers excellent EMI/RFI protection, high resistance to oxidation combined with high…

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. The typical attenuation value is 60 dB at 2.4; 5.8 and 7.125GHz. The RI 4199 offers SuperSpeed ​​20 Gbps data transfer, can handle a decent 100W of power, making it the…

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…
