Surface Mount Buried Single Layer™ Capacitors

Presidio Advantage

Alternative to wire-bondable capacitors for coupling on a micro-strip (Figures 1 & 2) or as bypass capacitor on coplanar waveguides (Figure 3)
Elimination of additional impedance caused by wire bonding
Minimum discontinuity in circuit elements
Select capacitance values and voltage ratings from application tables
Use Kent Simulator for modeling
RoHS compliant (except with ‘N’ termination)
