Type T491 Solid Tantalum Chip Capacitors Solid Tantalum .
Type T491 Solid Tantalum Chip CapacitorsSolid Tantalum Chip Capacitors for Surface Mount ApplicationsENTREPLACEMENTThe T491 Series’ physical outline and dimensions conform to the global standard for tantalum capacitor chips, and the T491 exceeds therequirements of EIA standard 535BAAC. T491chips are specifically for automated surfacemount processes and equipment. The terminations are 100% Matte-Tin. Reliability andthermal stability are assured by lead-frame attachments to the tantalum pellet made by microprocessor-controlled welding and a high temperature silver epoxy adhesive. Standard packaging is compatible with all tape-fed placementunits and with EIA RS- 481-1 tape and reel specification.Highlights ALIVEQU Low DF and DC LeakageTemperature Stable260 ºC for 10 Seconds SolderingMeets IECQ StandardQC300801/US0001Meets EIA Standard 535BAACR FO ETSpecificationsCapacitance Range:Voltage Range:Tolerance:Operating Temperature:Cap Change From Initial Limit:DISCONTINUEDCONTACTKEM0.10 µF to 330 µF4 Vdc to 50 VDC 10% standard, 20% available–55 ºC to 125 ºC (with proper derating)–10% @ –55 ºC; 10% @ 85 ºC; 12% @ 125 ºCDC Leakage: At 25 ºC — See RatingsAt 85 ºC — 10 x 25 ºC limitAt 125 ºC — 12 x 25 ºC limitDissipation Factor: 0.1 µF to 1.0 µF — 4%1.5 µF to 68 µF — 6%100 µF to 330 µF — 8%Standard Packaging Tape and Reel: EIA RS-481-1Complies with the EU Directive2002/95/EC requirementrestricting the use of Lead (Pb),Mercury (Hg), Cadmium (Cd),Hexavalent chromium (Cr(VI)),PolyBrominated Biphenyls (PBB)and PolyBrominated DiphenylEthers (PBDE).TapeCaseCodeEIAIECQQty per7" m12mm4mm4mm4mm4mm8mm8mm8mm13” Reels Available on Special OrderCDE Cornell Dubilier 1605 E.

Existing military specifications for surface mount solid tantalum capacitors (MIL-PRF-55365) do not address the issue of survivability of tantalum capacitors in reverse bias conditions. Users are left to consult guidelines offered by major manufacturers of tantalum capacitors. Generally speaking, these guidelines tend to be highly conservative
