Tantalum Surface Mount Capacitors - Standard Tantalum T491 Industrial Grade MnO2 Series Overview The KEMET T491 Series, 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. This series is classified as MSL (Mositure Sensitivity Level) 1 under J STD 020: unlimited floor life time at 30C / 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 and reel in accordance with EIA 481. This system provides perfect compatibility with all tape-fed placement 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 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.

Hand soldering should be performed with care due to the difficulty in process control. If performed, care should be 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 occurs. Once reflow occurs, the iron should be removed immediately. "Wiping" the edges of a chip and heating the top surface is not recommended. During typical reflow operations, a slight darkening of the goldcolored epoxy may be observed. This slight darkening is normal and not harmful to the product. Marking permanency is not affected by this change.

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. tP Maximum Ramp Up Rate = 3C/seconds Maximum Ramp Down Rate = 6C/seconds tL Tsmax Tsmin 25 tS 25C 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 40C 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. (c) KEMET Electronics Corporation * P.O.

Dimensions of embossment location and hole location shall be applied independent of each other. 2. The tape, with or without components, shall pass around R without damage (see Figure 4). 3. If S1 < 1.0 mm, there may not be enough area for cover tape to be properly applied (see EIA Standard 481-D, paragraph 4.3, section b). 4. B1 dimension is a reference dimension for tape feeder clearance only. 5. The cavity defined by A0, B0 and K0 shall surround the component with sufficient clearance that: (a) the component does not protrude above the top surface of the carrier tape. (b) the component can be removed from the cavity in a vertical direction without mechanical restriction, after the top cover tape has been removed. (c) rotation of the component is limited to 20 maximum for 8 and 12 mm tapes and 10 maximum for 16 mm tapes (see Figure 2). (d) lateral movement of the component is restricted to 0.5 mm maximum for 8 mm and 12 mm wide tape and to 1.0 mm maximum for 16 mm tape (see Figure 3). (e) see Addendum in EIA Standard 481-D for standards relating to more precise taping requirements. (c) KEMET Electronics Corporation * P.O.

Cover Tape Break Force: 1.0 Kg minimum. 2. Cover Tape Peel Strength: The total peel strength of the cover tape from the carrier tape shall be: Tape Width Peel Strength 8 mm 0.1 to 1.0 Newton (10 to 100 gf) 12 and 16 mm 0.1 to 1.3 Newton (10 to 130 gf) The direction of the pull shall be opposite the direction of the carrier tape travel. The pull angle of the carrier tape shall be 165 to 180 from the plane of the carrier tape. During peeling, the carrier and/or cover tape shall be pulled at a velocity of 300 10 mm/minute. 3. Labeling: Bar code labeling (standard or custom) shall be on the side of the reel opposite the sprocket holes. Refer to EIA Standards 556 and 624.
