EMI Catalog - Spectrum Control

PCB MountFiltered Terminal BlocksFiltered ArraysThe PCB mount filtered terminal block is designed to provideexcellent EMI/RFI filtering of low voltage DC powerlines and control lines. These new terminal blocks use aunique screw clamp system with a wire protector whichprovides for quick and easy installation. Spectrum’s PCBMount terminal blocks can be used for a variety of powersupply filtering applications in telecommunications equipment,metering, industrial controls, instrumentation andEDP equipment.Features■ Filter element provides high insertion lossfor EMI/RFI filtering of DC power and control lines■ Rugged construction provides protection to filteringelement; especially useful for repeated changes inwiring or field connections■ 2 to 12 terminals available (combine if largernumber of terminals needed)■ Quick and easy PCB installation and maintenance■ Cost-effective solution for industrialinterconnection EMI filtering problems■ Selectively loaded filter pins to economically meetexact filtering requirements■ Available with European (5 mm) or US (.200") pinspacing■ Available in RoHS compliant versionsOrdering InformationExample: 52-227-006-LThe part number shown represents a low profile PCBmount terminal block for thru-hole grounding with six terminals(US spacing).52 - * 227 - 006 - LSpecificationsELECTRICALC FilterOperating temperature: -40° C to 80° CWorking voltage: 100VDCCapacitance: 2500 pF* +80% / -20%Dielectricwithstanding voltage: 707VDCCurrent rating: 12 Amps max.D.C. resistance: .01 ohms max.Typical Insertion Loss — dB:In 50 Ohm Circuit10 MHz....... 10.4 500 MHz......... 43.950 MHz....... 23.9 1000 MHz......... 49.9100 MHz....... 29.9MECHANICALCenter spacing: US .200: (5.08 mm)EURO .197" (5 mm)Wire size: AWG 12 through 26Screw material: steel, zinc chromate plateRecommended PCBhole diameter: .05" (1.30 mm) contact holeMolded material: UL rated 94VO polyamideTightening torque: 2.5 in.-lbs. max.Terminal:Brass, tin-plated* For filter elements with additional capacitance values,consult factory.Terminal Block type227 U.S. pin spacing228 Metric pin spacingNumber ofterminals002 - 2 terminalsthru012 - 12 terminalsLow profilesizingSee page 126* Replace “–” with “F” for RoHS complaint version125SPECTRUM CONTROL INC. • 8031 Avonia Rd. • Fairview, PA 16415 • Phone: 814-474-2207 • Fax: 814-474-2208 • Web site: www.spectrumcontrol.comSPECTRUM CONTROL GmbH • Hansastrasse 6 • 91126 Schwabach, Germany • Phone: (49)-9122-795-0 • Fax: (49)-9122-795-58
