dimensions today's high frequency switch mode power supplies (smps) require high performance capacitors in the input and output filters. union technology has developed a line of mlcc smps filter caps with extremely low equivalent series resistance (esr) and low equivalent series inductance (esl) that offer improved performance at higher frequencies. these capacitors have been extensively tested and have performance characteristics meeting the demands for efficient capacitors in these stringent applications. union technology is approved to dscc drawings 87106 and 88011. parts can be screened to the requirements of mil-prf-49470 or customer drawings. 4 union technology corp. ?718 monterey pass road, monterey park, ca 91754 (323) 266-6603 ?fax (323) 266-7890 ?www.uniontechcorp.com military and commercial smps - switch mode power supply filter capacitors 50v 100v 200v 500v 50v 100v 200v 500v 50v 100v 200v 500v 100 56.0 27.0 12.0 150 82.0 39.0 18.0 47.0 27.0 12.0 5.6 4.7 3.3 1.8 0.82 5.6 4.7 2.7 1.2 2.2 1.8 1.0 0.39 voltage x7r npo case code 123 50v 100v 200v 500v 50v 100v 200v 500v 50v 100v 200v 500v 15.0 8.2 3.9 1.8 5.6 3.3 1.5 0.68 270 180 120 39.0 0.56 0.47 0.27 0.12 0.27 0.22 0.1 0.047 15.0 12.0 5.6 2.2 voltage x7r npo case code 456 maximum capacitance for each case-values in uf .450 1.950 2.075 .500 20 .800 1.450 1.535 .870 15 .450 .950 1.075 .500 10 1 2 3 case code .400 .350 .425 .440 4 .250 .224 .275 .300 3 1.250 1.950 2.075 1.350 20 4 5 6 c+ .025 e(max) number of leads per side d min max * for refer to table 1 and 2 on pages 9 and 10. ** for maximum "b" dimension add .065 inch to the appropriate "a" dimension.
