Vishay's NC series thin film, single-value chip and wire capacitors

Vishay Electronic : 19 September, 2003  (New Product)
Vishay Intertechnology, Inc. today announced the release of the NC Series of thin film, single-value chip and wire capacitors. With sizes ranging from 0.020 in. x 0.020 in. to 0.060 in. x 0.060 in. and capacitance values from 0.5 pF to 1000 pF, the new capacitors from Vishay Electro-Films offer smaller size, better performance, and superior stability when compared to thick film competitors.
Designed for assembly in hybrid circuits using conventional wire-bonding techniques, one epoxy attach and one wire bond - the five capacitor models released today provide a high degree of layout flexibility in RFI and EMI filters, bypass capacitors, CMOS digital filters, and low-pass filters in smart cards, passive electronic ID tags, and other hybrid products.

The new NCA, NCB, NCC, NCD, and NCE devices are available with a combination silicon dioxide/silicon nitride dielectric or, for critical microwave or high-frequency applications in which low dielectric absorption is required, with a silicon dioxide dielectric.

NCA capacitors measure 0.020 in. x 0.020 in. and offer a capacitance range of 0.5 pF to 51 pF. NCB capacitors measure 0.030 in. x 0.030 in. with a capacitance range of 33 pF to 100 pF, NCC devices measure 0.040 in. x 0.040 in. with a range of 56 pF to 220 pF, NCD devices measure 0.055 in. x 0.055 in. with capacitance values from 150 pF to 510 pF, and NCE capacitors are 0.060 in. x 0.060 in. with a range of 360 pF to 1000 pF. Tolerances down to 2.5% are available for the series.

NCA, NCB, and NCC capacitors each feature a single top contact, while the larger NCD and NCE versions provide three parallel, connected top contacts for bonding convenience. All five capacitor models feature a semiconductor silicon substrate, an aluminum bond pad measuring at least 0.005 in. x 0.005 in., and a gold backing. Manufactured with Vishay Electro-Films' sophisticated thin film equipment and manufacturing technology, NC Series capacitors have a standard thickness of 0.010 in. [0.25 mm].

The devices' compact dimensions and stable performance reduce signal drift, while their versatile pad layout allows for design of smaller end products. Compatibility with standard IC assembly methods help ensure low-cost assembly. The new capacitors are 100% electrically tested and visually inspected to MIL-STD-883.

Samples and production quantities of the NC Series thin film, single-value chip and wire capacitors are available now with a lead time of eight weeks for larger orders.
