EMI Catalog - Spectrum Control

100Typical Insertion LossFilter SelectionEMI Filter PerformanceThe electrical characteristics table and insertion lossgraphs indicate the performance of feed-thru capacitorsand Pi type filters. Utilize this information to specify theEMI filtering components included in your filter plate.Custom FilteringSpectrum Control filter plates are engineered toaccommodate selective line filtering. Several differenttypes of filters may be specified in a single, easy toinstall filter plate, allowing you to facilitate a wide rangeof filtering requirements.For selective line filtering, provide a sketch indicatingthe filters and positions required. The example belowrepresents a 10 pin, 2 row plate with six 1000 pF feedthrucapacitors and four 1700 pF Pi type filters.Part NumberBased on frontview of plate10 F1 FFFFFRRR 6R 5Insertion Loss (dB)Insertion Loss (dB)8060402000.1MHz 1MHz 10MHz 100MHz 1GHz)Frequency10080604020C-Style CapacitorPi CapacitorP00.1MHz 1MHz 10MHz 100MHz 1GHzFrequencyQGFAbove curves represent application of propergrounding fundamentals, for assistance consultwith Spectrum Control.RSHTIE D C B A10GHzLMNO10GHzFiltered ArraysFilterDesignationFilter**CircuitsValueCapacitanceTolerance3 dB MaxCut-offFrequency(MHz)*WorkingVoltage DC-55°C to+125°CA68 pF ±20% 77 100V — — — —B100 pF ±20%53 100V — — — —C135 pF +100/-0% 23 100V — — — 1D470 pF ±20%11 100V — — 2 7EC 820 pF ±20%6100V — 2 6 12F1000 pF ±20%5100V — 3 7 14G1500 pF ±20%3.5 100V 1 4 10 16H2500 pF +100/-0% 1.3 100V 5 11 17 23I4000 pF +100/-0% .8 100V 9 15 21 27J Insulated 10 pF Max.635 100V — — — —KGroundedInsert— — — —L68 pF ±20%65 100V — — — —M100 pF ±20%46 100V — — — —N135 pF +100/-0% 25 100V — — — 1O470 pF ±20%11 100V — — — 9PPi 820 pF ±20%6100V — — 4 13Q1000 pF ±20%5100V — 2 7 16R1700 pF +100/-0% 1.9 100V 1 6 14 28S2500 pF +100/-0% 1.3 50V 4 9 16 28T5000 pF +100/-0% .7 100V 9 15 28 41* 3 dB cut-off frequency calculated at the maximum capacitance.** For Hi-Density centers (2 mm) only C style filters are available, to a maximum of 4000pF.5MHzMinimum Insertion Loss - Decibels (dB)50 ohm system per MIL-STD-220 (no load)10MHz20MHz50MHz100MHz—15131820222934——126182324354153200MHz3610192426293538——6917223136495466500MHz101416253032363842——1722263645516470701GHz161920273335374046——232834435259697070All High-Density capacitorsare 50 volts @ 125°C.120SPECTRUM 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
