Solid Tantalum Chip Capacitors

No Preview Available !

Type T491 Solid Tantalum Chip Capacitors
Solid Tantalum Chip Capacitors for Surface Mount Applications
Highlights
Low DF and DC Leakage
Temperature Stable
260 ºC for 10 Seconds Soldering
Meets IECQ Standard
QC300801/US0001
Meets EIA Standard 535BAAC
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 Tin-Lead (SnPb) and 100% Matte-Tin
terminations are also available. 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.
Specifications

100 µF to 330 µF — 8%
Standard Packaging Tape and Reel: EIA RS-481-1
Complies with the EU Directive
2002/95/EC requirement
restricting the use of Lead (Pb),
Mercury (Hg), Cadmium (Cd),
Hexavalent chromium (Cr(VI)),
PolyBrominated Biphenyls (PBB)
and PolyBrominated Diphenyl
Ethers (PBDE).
