general information when mounted on an appropriate heat sink, these chip devices provide high power dissipation in terminations and as balancing resistors in wilkinson power divider networks. laser trimming provides maximum rf power capability. aluminum nitride is used for those applications where the use and disposal of beryllium oxide is a concern. ordering information series anc resistors, terminations high power chip, aluminum nitride C 50 & 100 ohms key : inches [millimeters] .xx .03 .xxx .010 [.x 0.8 .xx 0.25] notes 1. resistance value is expressed using military 4-digit call-out. 50r0 = 50 ohms 1000 = 100 ohms other values from 10C500 ohms may be available as special order. contact factory for availability. 2. tinning with sn96 lead free high temperature solder will maintain rohs compliance. general specifications solderable terminals electroplated silver over nickel substrate aluminum nitride resistive element thin film physical dimensions top view w b t l b type x (resistor) t l b type g (termination) 50 ohms or 100 ohms 50 ohms only 0.005 [0.13] max a (full film) (narrow film) example: typical model no. npc t 250-250 x j prefix tinning (see note 2) size terminal type (x or g) ohmic value (note 1) 50r0 or 1000 anc x tolerance key f= 1% g = 2% j = 5% (standard) (see note 1 below) h = sn96 t = sn63 capacitance termination w l t a b (pf) vswr power freq. model prefix in [mm] in [mm] in [mm] in [mm] in [mm] typical typical cw ghz anc 50-50 0.050 [1,27] 0.050 [1,27] 0.010 [0,25] n/a 0.010 [0,25] 0.5 1.25 5 dc-4.0 anc 50-100 0.050 [1,27] 0.100 [2,5] 0.010 [0,25] n/a 0.020 [0,51] 1.0 1.25 10 dc-2.0 anc 100-200 0.100 [2,5] 0.200 [5,1] 0.040 [1,02] n/a 0.030 [0,76] 1.0 1.25 10 dc-4.0 anc 200-200 0.200 [5,1] 0.200 [5,1] 0.040 [1,02] 0.085 [2,2] 0.040 [1,02] 1.2 1.25 30 dc-4.0 anc 250-250-40 0.250 [6,4] 0.250 [6,4] 0.040 [1,02] 0.085 [2,2] 0.050 [1,27] 1.0 1.15 40 dc-2.5 anc 250-250-80 0.250 [6,4] 0.250 [6,4] 0.040 [1,02] n/a 0.050 [1,27] 1.6 1.25 80 dc-1.0 anc 250-375 0.250 [6,4] 0.375 [9,5] 0.040 [1,02] n/a 0.050 [1,27] 4.5 1.25 125 dc-1.0 anc 350-225 0.350 [8,9] 0.225 [5,7] 0.040 [1,02] 0.045 [1,14] 0.050 [1,27] 1.4 1.25 100 dc-2.0 anc 375-375 0.375 [9,5] 0.375 [9,5] 0.040 [1,02] 0.250 [6,4] 0.050 [1,27] 4.5 1.25 200 dc-1.0 performance specifications rev 04/11 300 dino drive, ann arbor, mi 48103 tel: 888-244-6638 or 734-426-5553 ? fax: 734-426-5557 www.aeroflex.com/inmet ? inmetsales@aeroflex.com
