Surface Mount Filters and InductorsSelection GuideLC Type Chips■ SMD chips in EIA 0805 and 1206body sizes■ Available with cut-off frequencies from10 MHZ to 220 MHZ■ Steep insertion loss (IL) curvesLC chips are ideal for use in high frequencysignal lines as high-efficiency surface mountfilters. These non-polar chip filters are effectiveover a wide range of frequencies and featuresteep insertion loss characteristics. LC typechips are of monolithic construction utilizingdielectric and ferrite materials.Other KeyPagesPagesFilter Installation . . . . . . . . . . . . . .16Performance Testing . . . . . . . . .17-18Military Cross Reference . . . .237-239Terminology . . . . . . . . . . . . . . . . . . .44Land Patterns and SolderingProfiles . . . . . . . . . . . . . . . . . . . . . . .45Packaging and Storage . . . . . . . . . .46Competitive Cross Reference . . . . . .47LC Type Chips . . . . . . . . . . . . .54-55Square Surface Mount EMI Filters■ Square geometric for enhancedSMD soldering■ Pi circuits up to 10 amps■ Capacitance values up to 4000 pF■ Rated up to 100V DCHigh Current Power SMD EMI Filters■ PSM series■ Handles up to 20 amps■ 20 amps for Feed-Thrus■ 10 amps for Pi■ Rated up to 200V DC■ Capacitance values of 68 pF to 10,000 pF■ Superior performnce in GHz applicationsSquare surface mount EMI filters are designedto filter EMI/RFI on crowded printed circuitboards at currents up to 10 amps. These filterseliminate the need for thru-hole filters, therebygiving the designer the ability to create an “RFfence” without using high-cost RF bulkheads.Spectrum square surface mount EMI filters areof high temperature construction and may beinstalled utilizing pick-and-place equipment.Spectrum Control high current power SMDEMI filters are the first surface mount filtersdesigned to effectively filter EMI/RFI on printedcircuit boards operating at currents up to 20amps. These filters are of high temperatureconstruction and offer superior high frequencynoise suppression.SSM Series . . . . . . . . . . . . . . . .56-61PSM Series . . . . . . . . . . . . . . . .56-61Surface Mount Filters & InductorsHigh Frequency Thru-Hole PCB Filters■ Thru-hole design available in twoconfigurations■ Encapsulated capacitive and Ferrite toprotect against environmental concernsHigh frequency thru-hole PCB filters aidin meeting FCC and VDE requirements byproviding EMI filtering for protection of lowpower digital circuits. These filters mountdirectly to printed circuit board, allowing thefilter to be flow soldered with other components.Placement of one of these filters at the EMIproblem source could eliminate the need foradditional filtering at other circuit points.PCB Filters . . . . . . . . . . . . . . . . . .62SPECTRUM 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)-9122-795-5821
