EMI/EMC/RFI EMC Filters for High Power Inverters Rid Noise On Both AC and DC Lines Schurter has added the FMCC SOL to its filter line up, designed for high attenuation of electromagnetic interference in 3-Phase systems. Rated currents range from 150 to 2,500 A at 520 V or 760 V. The filter is considerably compact and lightweight, relative to its performance. As demand for more powerful and physically larger renewable energy systems increases, so too does the demand for increased system efficiency. This is achieved through higher performing sub-systems and ultimately the components within them. The FMCC SOL complements Schurter's existing FMER SOL DC filter for use in inverters where both AC and DC lines require filtering, such as those used for photovoltaic and wind harvesting systems. The FMCC SOL is also well suited for solo use in 3-Phase gridconnected industrial and commercial systems. Current ratings are provided for ambient temperatures of 50°C, as well as 40°C. Connections are made with bolt and nut or copper bars. Other connection types are possible, as well as modifications to the housing for custom fit. The FMCC SOL is UL approved with VDE approval pending. AVX Releases Transgaurd and StaticGuard Multilayer Varistors with Tin/Lead Terminations AVX Corp. has released the TransGuard and StaticGuard VCLD series multilayer varistors with Sn/Pb terminations, which feature a minimum of 5 percent lead (Pb). Designed specifically to support customers who cannot accept pure tin components in their applications, especially within the defense industry, the VCLD series varistors provide EMI/RFI attenuation and bi-directional overvoltage protection against transient events such as ESD, inductive switching, lightning and nuclear electromagnetic pulses (NEMP) in a single SMT package. Featuring fast response times to ESD strikes, multi-strike capabilities, high reliability, radiation resistance and EMI/RFI filtering in the off-state, the TransGuard and StaticGuard VCLD series multilayer varistors with Sn/Pb terminations are rated for use in temperatures spanning -55°C to 125°C. TransGuard VCLD series varistors are available in four cases sizes (0603, 0805, 1206 and 1210), 16 working voltages (spanning 5.6 VDC to 85 VDC), 13 energy ratings (spanning 0.05J to 2.0J) and 19 clamping voltages (spanning 18 V to 150 V). StaticGuard VCLD series varistors feature a working voltage of 18 VDC, a clamping voltage of 50 V and are availble in three case sizes (0603, 0805 and 1206) and two energy ratings (0.05J and 0.1J). Cima NanoTech Launches Ultra Low Resistance Sante EMI Shielding Film requirements, manufacturers also benefit from several properties of the Sante FS100-LR-1N EMI shielding films. These include a low surface resistance of <1 Ω/sq, enabling shielding performance of 45 dB to 55 dB attenuation between 30 MHz and 1.5 GHz. Sante FS100-LR-1N also has total transmittance of up to 75 percent while preserving the original color tone of the surface on which the films are applied. The proprietary Sante Nanoparticle Dispersion forms a random network pattern on the surface of the FS100-LR-1N film, thus overcoming moiré issues. As such, unlike standard metal mesh technology, the need to orientate a film to a non-moiré position on a display screen is eliminated, providing manufacturers with the benefit of low material wastage and ease of implementation. Teseq Expands CDN Line to Include Testing of USB 3.0, HDMI, Coaxial and 8-Line Cables Teseq has expanded its line of CDNs (coupling/ decoupling networks) for EMC RF conducted immunity testing, according to IEC/EN 61000-4-6, with several new models. The latest models include CDN USB 3.0, CDN HDMI, CDN S502, CDN S752 and CDN A801. Designed for use with shielded USB cables, the CDN USB 3.0 offers testing of all existing USB interfaces. It is compatible with USB versions 1.0, 1.1, 2.0 and 3.0 (also called Superspeed USB) and is fitted with a nine pin "A" type connector on EUT (equipment under test) and AE (auxiliary equipment) ports. The CDN USB 3.0 allows higher transfer rates of up to 4.8 Gb/s, increased maximum bus power and now full-duplex data transfers. It also improves the interaction between the device and host computer. Teseq's CDN USB 3.0 is capable of testing all the latest USB technology including digital cameras, high definition displays, hi-end solid-state drives and RAID arrays. Teseq's CDN HDMI, designed for screened multimedia cables, can be used in all high speed HDMI applications including DVD players, Blu-ray DVD, gaming systems, cameras, camcorders and cable TV decoders. This CDN is fitted with an HDMI "A" type connector on EUT and AE ports. All 19 pins are connected for compatibility with high speed HDMI version 1.4 with HDCP, HEC (Ethernet), ARC and DSC. Both the CDN S502 and CDN S752 allow testing on coaxial 50 Ohm and 75 ohm interfaces. Each CDN is fitted with "N" type connectors on EUT and AE ports. A double-screened cable within the CDNs allows for the most consistent test results. Also available from Teseq are 50 ohm and 75 ohm CDNs with BNC connectors. Teseq's new 8-line CDN, the CDN A801, from 150 kHz to 300 MHz, and CDN A801-10, from 10 kHz to 80 MHz are designed for testing unscreened and unbalanced control interfaces. These CDNs are fitted with 4 mm banana connectors on EUT and AE ports, which allow them to be easily adapted to a wide variety of control interfaces such as RS-232, RS-422, RS-485 or custom interfaces. Cima NanoTech has unveiled its lightweight, thin and transparent EMI shielding film, Sante FS100-LR-1N. Sante FS100-LR-1N is a transparent EMI shielding solution that allows manufacturers more freedom in product design without compromising on optics and shielding performance.
