Overview:

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 microstructure is composed of a conducting titanate ceramic grain in contact with an insulating Grain Boundary 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.

Key Features:

• GBBL Dielectric Yields High Capacitance vs Size
• Stable Temperature Coefficient: ±15% Max (-55°C to 125°C)
• Reduced Microphonics
• Offered With or Without Borders
• Thin Film TiW/Au or TiW/Ni/Au Electrodes
