Standard MnO₂Tantalum Surface Mount Capacitors

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.

The T491 standard terminations are 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. Lead frame attachments to the

tantalum pellet are made via a microprocessor-controlled welding

operation, and a high temperature silver epoxy adhesive system.

This product meets or exceeds the requirements of EIA standard

535BAAC. The physical outline and dimensions of this series

conform to this global standard. Five low proﬁle case sizes

are available in the T491 Series. The R/2012-12, S/3216-12

and T/3528-12 case sizes have a maximum height of 1.2 mm.

The U/6032-15 size has a maximum height of 1.5 mm, and the

V/7343-20 has a maximum height of 2.0 mm.

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 desity 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.

KEMET’s families of surface mount tantalum capacitors are

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

sensitivety testing. The devices can safely withstand a maximum of

three reﬂow passes at these conditions.

Note that although the X/7343-43 case size can withstand wave

soldering, the tall proﬁle (4.3mm maximum) dictates care in wave

process development.

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 degrees C, and maximum storage humidity not

exceed 60% relative humidity. In addition, 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.

Tape & Reel Packaging Information

KEMET’s Molded Tantalum and Aluminum Chip Capacitor families

are packaged in 8 mm and 12 mm plastic tape on 7" and 13"

reels, in accordance with EIA Standard 481-1: Taping of Surface

Mount Components for Automatic Handling. This packaging

system is compatible with all tape fed automatic pick and place

systems.

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 Document 481 paragraph 4.3 (b)).

4. B1 dimension 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 12mm tapes and 10° maximum for 16mm tapes (see Figure 3).

(d) lateral movement of the component is restricted to 0.5 mm maximum for 8mm and 12mm wide tape and to 1.0mm maximum for 16mm tape (see Figure 4).

(e) for KPS Series product A₀and B₀are measured on a plane 0.3mm above the bottom of the pocket.

(f) see Addendum in EIA Document 481 for standards relating to more precise taping requirements.
