Tantalum Surface Mount Capacitors – Standard Tantalum T491 Industrial Grade MnO2 Overview The KEMET T491, designed specifically for today’s highly automated surface mount processes and equipment, is the leading choice for surface mount designs. The T491 combines KEMET’s proven solid tantalum technology, acclaimed and respected throughout the world, with the latest in materials, processes, and automation, resulting in unsurpassed total performance and value. This product meets or exceeds the requirements of EIA standard 535BAAC. The T491 is classified as moisture sensitivity level (MSL) 1 under J STD 020, with unlimited floor life time at ≤ 30°C/85% RH. The T491 standard terminations are available in 100% matte tin and provide excellent wetting characteristics and compatibility with today's surface mount solder systems. Tin/lead (Sn/Pb) terminations are available upon request for any part number. Gold-plated terminations are also available for use with conductive epoxy attachment processes. Standard packaging of these devices is Tape & Reel in accordance with EIA 481. This system provides perfect compatibility with all tape-fed placement units. Benefits • Meets or exceeds EIA Standard 535BAAC • Tape & Reel standard packaging per EIA 481 • Symmetrical, compliant terminations • Optional gold-plated terminations • Laser-marked case • 100% surge current test on C, D, E, U, V, and X sizes • Halogen free epoxy • Capacitance 0.1 – 1,000 µF • Tolerance ±10%, ±20% • Voltage 2.5 – 50 VDC • Extended range values • Low profile case sizes • RoHS compliant and lead-free terminations • Operating temperature range of −55°C to +125°C Click image above for interactive 3D content Open PDF in Adobe Reader for full functionality Applications Typical applications include decoupling and filtering in many end applications, such as DC/DC converters, portable electronics, telecommunications, and control units.

Permissible AC ripple voltage which may be applied is limited by two criteria: 1. The positive peak AC voltage plus the DC bias voltage, if any, must not exceed the DC voltage rating of the capacitor. 2. The negative peak AC voltage in combination with bias voltage, if any, must not exceed the allowable limits specified for the reverse voltage. See the Reverse Voltage section for allowable limits. The maximum power dissipation by case size can be determined using the table at right. The maximum power dissipation rating stated in the table must be reduced with increasing environmental operating temperatures. Refer to the table below for temperature compensation requirements. Temperature Compensation Multipliers for Maximum Ripple Current T ≤ 25°C 1.00 T ≤ 85°C 0.90 T ≤ 125°C 0.40 T = Environmental Temperature The maximum power dissipation rating must be reduced with increasing environmental operating temperatures.

Provides a robust solder attachment condition for reflow solder processes. Density Level C: For high component density product applications. Before adapting the minimum land pattern variations, the user should perform qualification testing based on the conditions outlined in IPC standard 7351 (IPC–7351). 1 Height of these chips may create problems in wave soldering. 2 Land pattern geometry is too small for silkscreen outline.

Preheating of these components is recommended to avoid extreme thermal stress. KEMET's recommended profile conditions for convection and IR reflow reflect the profile conditions of the IPC/J-STD-020D standard for moisture sensitivity testing. The devices can safely withstand a maximum of three reflow passes at these conditions. Please note that although the X/7343–43 case size can withstand wave soldering, the tall profile (4.3 mm maximum) dictates care in wave process development.

This slight darkening is normal and not harmful to the product. Marking permanency is not affected by this change.

If performed, care should be * For Case Size height > 2.5 mm ** For Case Size height ≤ 2.5 mm taken to avoid contact of the soldering iron to the molded case. The iron should be used to heat the solder pad, applying solder between the pad and the termination, until reflow TP tP Maximum Ramp-up Rate = 3°C/second occurs. Once reflow occurs, the iron should be removed Maximum Ramp-down Rate = 6°C/second TL immediately. “Wiping” the edges of a chip and heating the top tL surface is not recommended. Tsmax Tsmin 25 ts 25°C to Peak Time Storage Tantalum chip capacitors should be stored in normal working environments. While the chips themselves are quite robust in other environments, solderability will be degraded by exposure to high temperatures, high humidity, corrosive atmospheres, and long term storage. In addition, packaging materials will be degraded by high temperature – reels may soften or warp and tape peel force may increase. KEMET recommends that maximum storage temperature not exceed 40°C and maximum storage humidity not exceed 60% relative humidity. Temperature fluctuations should be minimized to avoid condensation on the parts and atmospheres should be free of chlorine and sulphur bearing compounds. For optimized solderability, chip stock should be used promptly, preferably within three years of receipt. © KEMET Electronics Corporation • KEMET Tower • One East Broward Boulevard Fort Lauderdale, FL 33301 USA • 954-766-2800 • www.kemet.com T2005_T491 • 1/6/2021 16 Tantalum Surface Mount Capacitors – Standard Tantalum T491 Industrial Grade MnO 2 Construction Polarity Stripe (+) Molded Epoxy Case Detailed Cross Section Silver Paint (Fourth Layer) Polarity Bevel (+) Tantalum Wire Leadframe (− Cathode) Washer Tantalum Wire Weld (to attach wire) Carbon (Third Layer) Silver Adhesive Leadframe (+ Anode) Molded Epoxy Case MnO2 (Second Layer) Washer Ta2O5 Dielectric (First Layer) Tantalum Capacitor Marking Date Code * 1 digit = last number of year 5 = 2015 6 = 2016 7 = 2017 8 = 2018 9 = 2019 0 = 2020 2nd and 3rd digit = week of the year 01 = 1st week of the year to 52 = 52nd week of the year st KEMET Industrial Grade MnO2 Polarity Indicator (+) Picofarad Code KEMET ID Rated Voltage Date Code* * 016 = 16th week of 2020 © KEMET Electronics Corporation • KEMET Tower • One East Broward Boulevard Fort Lauderdale, FL 33301 USA • 954-766-2800 • www.kemet.com T2005_T491 • 1/6/2021 17 Tantalum Surface Mount Capacitors – Standard Tantalum T491 Industrial Grade MnO 2 Tape & Reel Packaging Information KEMET’s molded chip capacitor families are packaged in 8 and 12 mm plastic tape on 7" and 13" reels in accordance with EIA Standard 481: Embossed Carrier Taping of Surface Mount Components for Automatic Handling.
