piconics, inc. tt series piconics tt series, a molded top tuned inductor, is desi gned for use in high-density printed circuit boards where surrounding components prevent side tuning. it occupies one third the volume of a to-5 can. the inductor has a molded case and utilizes a self-locking tuning screw. th ese inductors can be converted to transformers by additional taps and leads as required. our standard cons truction uses solid .018" tinned copper leads for values below 1uh. from 1uh to 100uh .018 gold plated kovar leads are used. for values above 100uh, .013" gold plated kovar leads are used because the ratio of the winding wire to the lead wire is less and the weld re liability is higher. the series is listed in the qualified products li st (qpl) 15305 under the identifier ms 53233 and 53234. part number lmax uh lmin uh qmin at lmax test freq mhz srf min mhz dcr max ohms idc max ma tt250-8i-10 .025 .020 50 200 1000 .04 250 tt510-80-10 .051 .036 40 100 700 .05 250 tt760-8i-10 .076 .055 40 100 615 .15 250 TT101-8I-10 .10 .075 30 25 500 .50 250 tt151-8i-10 .15 .11 30 25 420 .50 200 tt221-8i-10 .22 .16 30 25 400 .60 180 tt271-8i-10 .27 .19 30 25 400 .80 180 tt331-8i-10 .33 .24 30 25 320 .90 140 tt471-8i-1- .47 .34 30 25 290 1.0 100 tt561-8i-10 .56 .40 30 25 250 1.1 100 tt681-8i-10 .68 .50 30 25 240 1.3 100 tt821-8i-10 .82 .59 30 25 180 1.4 100 tt102-6i-00 1.0 .67 25 7.9 140 1.5 100 tt152-6i-00 1.5 1.0 25 7.9 135 1.6 100 tt222-6i-00 2.2 1.5 25 7.9 100 2.1 80 tt272-6i-00 2.7 2.0 25 7.9 60 2.4 75 tt332-6i-00 3.3 2.2 25 7.9 55 2.7 65 tt472-6i-00 4.7 3.2 25 7.9 50 3.3 60 tt582-6i-00 5.8 3.9 25 7.9 36 4.2 58 tt682-6i-00 6.8 4.5 25 7.9 34 4.5 55 tt822-6i-00 8.2 5.5 25 7.9 32 4.5 50 tt103-3f-00 10 6.0 22 2.5 30 4.5 50 tt133-3f-00 13 6.5 22 2.5 28 4.5 50 tt163-3f-00 16 8 22 2.5 26 5.1 50 tt203-3f-00 20 10 22 2.5 20 5.3 43 tt223-3f-00 22 11 22 2.5 14 6.0 43 tt303-3f-00 30 15 22 2.5 10 6.8 40 tt363-3f-00 36 18 22 2.5 9 7.5 40 tt473-3f-00 47 24 22 2.5 6.5 8.6 39 tt563-3f-00 56 28 22 2.5 6.3 10.5 35 tt683-3f-00 68 34 22 2.5 6.2 12.0 30 tt753-3f-00 75 38 22 2.5 5.9 13.5 30 tt863-3f-00 86 43 22 2.5 5.6 15.0 28 tt104-3f-00 100 50 20 .79 5.4 18.0 27 tt124-3f-01 120 60 20 .79 4.4 21.0 25 tt474-3f-01 470 240 20 .79 2.1 45.0 16 tt684-1f-01 680 340 20 .79 2.0 53.0 15 tt105-1f-01 1000 500 20 .25 1.1 113 11 features: ? self-locking adjustment screw ? high reliability ? top tuning ? molded case ? style military lti1 o grade 2 o class a absolute maximum ratings: ? operating temperature: -55 c to +125 c. ? storage temperature: -55 c to 125 c. ? power dissipation: 225 mw max ? dielectric withstanding voltages: sea level 1,000v rms min 70,000 feet 300v rms min. physical characteristics: ? terminal pull: tt250-81 through tt104-3f: 2lb. min tt124-3f through tt105-1f: 1.lb. min ? stop torque: .2 in.oz.max ? tuning torque: .005-2 in.oz.max ? weight: .25 gram max ? case: diallyl phthalate.
