The CBA MOS capacitor chips each contain four different
capacitors in binary increments allowing the user many
choices in value selection. Two versions of CBA capacitors
are available: one with a total capacitance of 3.75 pF and
one with a total capacitance of 15 pF.
These chips are manufactured using Vishay Electro-Films
(EFI) sophisticated Thin Film equipment and manufacturing
technology. The CBAs are 100 % electrically tested and
visually inspected to MIL-STD-883.
APPLICATIONS
Vishay EFI CBA binary MOS multi-value capacitor chips are
designed for hybrid packages in which microwave circuits
are to be trimmed. This is done on the CBA chips by
selecting the bonding pad for the required capacitance and
wire-bonding by conventional techniques.
