avx has developed the active filter series to address the emissions and susceptibility problems typical of today s high speed digital circuits. the active filter series is the equivalent of back-to-back zener diodes and an emc capacitor integrated into a single 0603 smt case size. in its off state the active filter series can be used to attenuate emi/rfi. typical values of attenuation at 3db are 450mhz - 5000mhz, and typical values of attenuation at 10db are 950mhz - 2600mhz. a more definitive representation of the filter effect is shown in the s 21 curve. one of the specific advantages of the active filter series is a consistent emi attenuation across a large bandwidth (without multiple frequency poles occurring). this makes compliance to electromagnetic susceptibility and emission specifications such as fcc part 68, sae j1113 and iec 61000-4-2 a much easier task for the designer. 0603 active filter series how to order afs style active filter series 0001 case size 0001 = 0603 discrete p termination p = plated (ni/sn alloy) d packaging code (reel size) d = 7" reel (1,000 pcs.) r = 7" reel (4,000 pcs.) t = 13" reel (10,000 pcs.) general description performance characteristics parameter test limit condition peak pulse 1ms, ta 25? 7.5 w power dissipation ta 25?, fr-4 225 mw power dissipation ta 25?, alumina 300 mw zener voltage 1ma 80 v device capacitance 1 mhz 27 pf (max) peak current 2.5 a reverse recovery time 600 ps turn on time 600 ps operating temperature -65 to +150? storage temperature -65 to +150? mechanical specifications cte (ppm / ?) 6.1 ppm/? thermal conductivity 0.5 (w/cm)/? 0 -5 -10 -15 -20 10 100 1000 frequency (mhz) s21 (db) 10000 s 21 curve 10000 1000 100 10 10 100 1000 10000 pulse duration ( typical pulse rating curve a kyocera group company
physical dimensions millimeters (inches) solder pad dimensions millimeters (inches) 0603 active filter series typical infrared reflow process (ir) soldering with ir has the highest yields due to controlled heating rates and solder liquidus times. only the dwell time and peak temperature limitations of resin-molded components need to be considered. typical recommended solder paste wet layout is 6 mils. application the active filter series is an important step towards integra- tion of several active and passive devices into one package. integration in turn creates a major size reduction for board layout engineers. typical size reductions of >90% can be achieved by replacing diode packages and associated emc capacitors with an avx active filter device. an example of such replacement is shown on the right. in addition, overall system reliability is improved with the afs due to a fit of 0.1 failures (per billion hours). 215-219 c 183 c 100 c preheat zone activates solder flux allows uniform board heating 250 200 150 100 50 0 01234 time in minutes ir reflow solder profile temperature c 45-80 sec. above solder melting point natural cool down avx myrtle beach, sc corporate offices tel: 843-448-9411 fax: 843-626-5292 avx northwest, wa tel: 360-669-8746 fax: 360-699-8751 avx north central, in tel: 317-848-7153 fax: 317-844-9314 avx mid/pacific, mn tel: 952-974-9155 fax: 952-974-9179 avx southwest, az tel: 480-539-1496 fax: 480-539-1501 avx south central, tx tel: 972-669-1223 fax: 972-669-2090 avx southeast, nc tel: 919-878-6357 fax: 919-878-6462 avx canada tel: 905-564-8959 fax: 905-564-9728 avx limited, england european headquarters tel: ++44 (0)1252 770000 fax: ++44 (0)1252 770001 avx s.a., france tel: ++33 (1) 69.18.46.00 fax: ++33 (1) 69.28.73.87 avx gmbh, germany - avx tel: ++49 (0) 8131 9004-0 fax: ++49 (0) 8131 9004-44 avx gmbh, germany - elco tel: ++49 (0) 2741 2990 fax: ++49 (0) 2741 299133 avx srl, italy tel: ++390 (0)2 614571 fax: ++390 (0)2 614 2576 avx czech republic, s.r.o. tel: ++420 (0)467 558340 fax: ++420 (0)467 558345 avx/kyocera, singapore asia-pacific headquarters tel: (65) 258-2833 fax: (65) 350-4880 avx/kyocera, hong kong tel: (852) 2-363-3303 fax: (852) 2-765-8185 avx/kyocera, korea tel: (82) 2-785-6504 fax: (82) 2-784-5411 avx/kyocera, taiwan tel: (886) 2-2696-4636 fax: (886) 2-2696-4237 avx/kyocera, china tel: (86) 21-6249-0314-16 fax: (86) 21-6249-0313 avx/kyocera, malaysia tel: (60) 4-228-1190 fax: (60) 4-228-1196 elco, japan tel: 045-943-2906/7 fax: 045-943-2910 kyocera, japan - avx tel: (81) 75-604-3426 fax: (81) 75-604-3425 kyocera, japan - kdp tel: (81) 75-604-3424 fax: (81) 75-604-3425 a kyocera group company http://www.avxcorp.com usa europe asia-pacific notice: specifications are subject to change without notice. contact your nearest avx sales office for the latest specification s. all statements, information and data given herein are believed to be accurate and reliable, but are presented without guarantee, warranty, or responsibility of any kind, expressed or implied. statements or suggestions concerning possible use of our products are made without representation or warranty that any such use is free of patent infringement and are not recommendations to infringe any patent. the user should not assume that all safety measures are indicated or that other measure s may not be required. specifications are typical and may not apply to all applications. s-afs2.5m0701-n length 1.6 ?.15 (0.063 ?.006) width 0.8 ?.15 (0.031 ?.006) thickness 0.9 max.
