Tantalum Surface Mount Capacitors – Automotive

T491 Industrial Grade MnO₂Series

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. The physical outline

and dimensions of this serie conform to this global standard.

Five low proﬁles case sizes are available 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 with

today's technology. Standard packaging of these devices is tape

and reel in accordance with EIA 481–1. This system provides

perfect compatibility with all tape-fed placement units.

Reverse Voltage

Solid tantalum capacitors are polar devices and may be permanently damaged or destroyed if connected with the wrong polarity. The

positive terminal is identiﬁed on the capacitor body by a stripe plus in some cases a beveled edge. A small degree of transient reverse

voltage is permissible for short periods per the table. The capacitors should not be operated continuously in reverse mode, even within

these limits.

Density Level A: For low-density product applications. Recommended for wave solder applications and provides a wider process window for reﬂow solder processes.

Density Level B: For products with a moderate level of component density. 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).

Soldering Process

KEMET’s families of surface mount capacitors are compatible

with wave (single or dual), convection, IR, or vapor phase reﬂow

techniques. 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.

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.

Note: All temperatures refer to the center of the package, measured on the

package body surface that is facing up during assembly reﬂow.

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 40ºC 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.

1. The embossment hole location shall be measured from the sprocket hole controlling the location of the embossment. 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 5).

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. B₁dimension is a reference dimension for tape feeder clearance only.

5. The cavity deﬁned by A₀, B₀and K₀shall 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.

Packaging Information Performance Notes

1. 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

8 mm

Peel Strength

0.1 to 1.0 Newton (10 to 100 gf)

0.1 to 1.3 Newton (10 to 130 gf)

12 and 16 mm

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.
