Type T491 Solid Tantalum Chip Capacitors

Solid Tantalum Chip Capacitors for Surface Mount Applications

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.
