EMI/EMC/ESD LCR Electronics Offers Quick Delivery on New EMI Filters that Eliminate RF Interference LCR Electronics has introduced two new series of EMI Filters for magnetic resonance imaging shielded rooms. The 058 series filters are designed to mitigate any unwanted EMI noise through MRI room telephone, alarm and data lines. The ULrecognized 059 series filters provide EMI suppression along the main power lines. The 058 series is a collection of dual line filters rated 120/277 VAC 50/60 Hz up to 50 A at 60°C, 300/600 VDC line-to-ground and line-to-line, all with an impendence line-to- line rating of 600 ohms and a line-to-ground rating of 300 ohms. The series has a stop band of 100 dB from 20 KHz to 10 GHz for phone lines, 100 dB from 150 KHz to 10 GHz for data lines and 100 dB from 14 KHz to 1 GHz for alarm lines. Individual or multiple 058 series filters can be supplied preinstalled in an enclosure with removable covers for I/O connections and a threaded conduit pipe for installation against shielded room interference. The cabinets with multiple filters are supplied with insulation displacement or screw down type terminal blocks for I/O connections. The 059 MRI room power line filters are available in single, dual and three phase configurations. They provide 100 dB attenuation from 5 MHz to 10 GHz per MIL-STD-220 and feature a sealed filter compartment with a removable shielded cover for input connections as well as a threaded conduit pipe for installation against shielded room interference. The output terminals are prewired with flexible cable extended out through the threaded conduit pipe. The 059 series is also available in low leakage line-to-line and three phase delta configurations for European applications or where lower leakage current is required. The filters are available for single and three phase applications rated 277 VAC 50/60 Hz up to 50 A at 60°C. EMC Solution with 3-Phase SINE Wave Filters Schurter has expanded its output filter portfolio for improved EMC with the introduction of the 3-phase sine wave output filters, series FMAC SINE and FMAC SINE DCL. The new sine wave filters are designed to convert output voltage wave forms produced by PWM (pulse width modulation) frequency converters into low distortion sine wave forms for motor and power transformation applications resulting in significantly increased efficiency and life. The Schurter sine wave filters are intended for use in 500 VAC installations and currents upwards of 4 A. The FMAC SINE and the FMAC SINE DCL operating voltage is 3 by 288/500 VAC and rated currents range from 4 to 16 A. Both have screw clamp terminals and screw on mounting to the chassis. They are designed for use in motors with power from 1.5 to 7.5 kW, frequency 0 to 200 Hz and switching frequency of 2 to 20 kHz. The new sine wave filters allow the use of long, lightweight and cost effective unshielded motor cables. FMAC SINE is optimized for motor cables up to 200 m. The FMAC SINE DCL includes a voltage DC link and efficiently accommodates motor cables up to 1,000 m under full load. New SlimShield Two-Piece Board Level Shielding Offers Shield Heights Down to 0.060 inches MOVING MANUFACTURING FORWARD. SOUTH-TEC brings together leading companies demonstrating industry’s newest technologies. This year, Keynote Sessions and an Emerging Technology Showcase highlighting micro, nano, and additive manufacturing enhance the SOUTH-TEC experience. Are you looking for technology, innovations, and ideas? Come to SOUTH-TEC and move your manufacturing forward! southteconline.com • 800.733.4763 Media Partner SOUTH-TEC is produced by SME Tech-Etch has introduced the SlimShield, a low-profile, two-piece board level shielding line with a dimpled cover that snaps into etched holes on the fence and offers shield heights as low as 0.060 inches. Standard dimple tooling offers variable dimple location with added cover retention at lower cost. There is no tooling cost on standard two-piece designs. An optional flange for added rigidity is available on larger fence designs. Multi-cavity designs are achieved by incorporating internal fences enabling multiple components to be shielded with the same part. Mounting pins are offered in any configuration. There is no additional cost for holes and slots for heat dissipation, as well as logos and part numbers. A configurable PDF sales drawing for the new low-profile board level shields can be downloaded from the Web site. Tech-Etch also offers standard one-piece designs with depthetched bend lines for hand forming, as well as standard two-piece designs that utilize a spring-finger style attachment between fence and cover. Custom designs offer unlimited possibilities for materials and shapes. 16 September/October 2011 www.ElectronicsProtectionMagazine.com http://www.southteconline.com http://www.southteconline.com http://www.ElectronicsProtectionMagazine.com
