NC Series
Vishay Electro-Films
Thin Film Single Value
Chip and Wire Capacitors
The NC series of thin film capacitors has the advantage of
increased performance and smaller size when compared
with its thick film counterparts. These chips are available in
sizes down to 20 mil square and in capacitances up to
1000 pF.
Parts require epoxy or eutectic die attach to substrate and
one wire bond.
These chips are manufactured using Vishay Electro-Films
(EFI) sophisticated Thin Film equipment and manufacturing
technology. The NC’s are 100 % electrically tested and
visually inspected to MIL-STD-883.
FEATURES
•Wire bondable
•Small size: 0.020 to 0.060 inches square
•Substrate: Silicon with gold backing
•Dielectric: Silicon dioxide/silicon nitride
•Capacitance range: 0.5 pF to 1000 pF
APPLICATIONS
The NC series of capacitor chips are designed for assembly in hybrid circuits using conventional wire-bonding techniques. They
provide excellent stability and performance, and their small size gives the hybrid designer greater layout flexibility. They are
available as MNOS or MOS capacitors. The MOS version is to be preferred when low dielectric absorption is required.
