Specifications
Highlights
The T491 Series’ physical outline and dimen-
sions conform to the global standard for tanta-
lum capacitor chips, and the T491 exceeds the
requirements of EIA standard 535BAAC. T491
chips are specifically for automated surface
mount processes and equipment. The termina-
tions are 100% Matte-Tin. Reliability and
thermal stability are assured by lead-frame at-
tachments to the tantalum pellet made by micro-
processor-controlled welding and a high tem-
perature silver epoxy adhesive. Standard pack-
aging is compatible with all tape-fed placement
units and with EIA RS- 481-1 tape and reel speci-
fication.

Cornell Dubilier strives to apply the most stringent quality and safety standards regarding the design
and manufacturing of its products, in light of the current state of the art, isolated component failures may
still occur. Accordingly, customer applications which require a high degree of reliability or safety should
employ suitable designs or other safeguards (such as installation of protective circuitry or redundancies
or other appropriate protective measures) in order to ensure that the failure of an electrical component
does not result in a risk of personal injury or property damage. Although all product-related warnings,
cautions and notes must be observed, the customer should not assume that all safety measures are indi-
cated in such warnings, cautions and notes, or that other safety measures may not be required.
