GBBL B
Johanson Technology’s new “GBBL” microwave capacitor features high capacitance per case size without sacrificing
the temperature stability associated with high dielectric constant materials. GBBL capacitors feature a proprietary
X7R composition which is manufactured by a two step, atmospheric controlled sintering process. The resulting micro-
structure is composed of a conducting titanate ceramic grain in contact with an insulating Grain Boundary Barrier
Layer (GBBL). The insulating boundary layer acts as a very thin dielectric. The process control of the boundary
thickness, in conjunction with the conductive grain size, provides the cumulative effect of a very high, yet stable,
dielectric constant.
