Tantalum Surface Mount Capacitors – Automotive Grade T491 Automotive/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 physical outline and dimensions of T491 conform to this global standard. Low profile case sizes are available. This series 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. The symmetrical terminations offer total compliancy to provide the thermal and mechanical stress relief required for today's technology. 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 • Extended range values • Low profile case sizes Applications Typical applications include decoupling and filtering in automotive end applications such as DC/DC converters, portable electronics, telecommunications, and control units. Environmental Compliance RoHS compliant (6/6) according to Directive 2002/95/EC when ordered with 100% Sn solder, Gold-plated or Non-magnetic 100% Sn solder. • Halogen-free • Epoxy compliant with UL94 V-0 • Molded Epoxy complies for outgassing testing under ASTM E 595.

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 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.

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.

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 • One East Broward Boulevard Fort Lauderdale, FL 33301 USA • 954-766-2800 • www.kemet.com T2050_T491_AUTO • 12/6/2023 12 Tantalum Surface Mount Capacitors – Automotive Grade T491 Automotive/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 8 = 2018 9 = 2019 0 = 2020 1 = 2021 2 = 2022 3 = 2023 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* * 301 = 1st week of 2023 © KEMET Electronics Corporation • One East Broward Boulevard Fort Lauderdale, FL 33301 USA • 954-766-2800 • www.kemet.com T2050_T491_AUTO • 12/6/2023 13 Tantalum Surface Mount Capacitors – Automotive Grade T491 Automotive/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.
