CAP-AVX-GX02-001 surface mount chip capacitor model CAP-AVX-GX02-001 is a substrate scalable model for the avx gx02zz104mat2 (0.1uf) ultra broad band capacitor. the model is for use with microstrip applicat ions and accounts for substrate (or printed circuit board) related parasitic effects. substrate height, die lectric constant, loss tangent, interconnect metal thick- ness, component tolerance, pad width, pad length, and pad gap are model input parameters. effective se- ries resistance (esr) was measured to 1ghz and incorporat ed into the model. a sim_mode switch allows pad stack effects to be disabled. this model has been val idated to 65 ghz on a 5 mil alumina substrate, and to lower frequencies using additional printed circu it board materials (see technical notes). model features land pattern (pad) scalable substrate scalable broadband (dc to 65 ghz) equivalent circuit topology accurate effective series resistance dc blocking capacitor developed for microstrip interconnects model description CAP-AVX-GX02-001 dc block 0402 body style substrate scaling legend: 4mil rogers 4350b, + 60mil rogers 4003, 5mil alumina, lines - model, symbols - measured da ta. measured data stops at highest valid frequency for each substrate (4 mil - 30 ghz, 60 mil - 8 ghz, 5 mil alumina - 6 5 ghz). note: the pad dimensions used for the plots are: p adl = 15.5mil, padw = 28.0mil, padg = 16.0mil www.modelithics.com sales@modelithics.com rev. 100714 ? 2010
