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 applications and accounts for substrate (or printed circuit

board) related parasitic effects. Substrate height, dielectric 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 incorporated into the model. A Sim_mode switch allows

pad stack effects to be disabled. This model has been validated to 65 GHz on a 5 mil Alumina substrate,

and to lower frequencies using additional printed circuit board materials (see Technical Notes).
