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 CAP-AVX-GX02-001 DC Block 0402 Body Style Model Description 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 thickness, component tolerance, pad width, pad length, and pad gap are model input parameters. Effective series 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).
