Tantalum Surface Mount Capacitors – Automotive

T491 Industrial Grade MnO₂Series

Overview

TheꢀKEMETꢀT491ꢀSeries,ꢀdesignedꢀspeciﬁcallyꢀforꢀtoday’sꢀ

highly automated surface mount processes and equipment,

is the leading choice for surface mount designs. The T491

combinesꢀKEMET’sꢀprovenꢀsolidꢀtantalumꢀtechnology,ꢀ

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.

FiveꢀlowꢀproﬁlesꢀcaseꢀsizesꢀareꢀavailableꢀꢀTheꢀT491ꢀstandardꢀ

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.

Ripple Current/Ripple Voltage

Permissible AC ripple voltage and current are related to equivalent

series resistance (ESR) and the power dissipation capabilities of

the device. 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,ꢀifꢀany,ꢀmustꢀnotꢀexceedꢀtheꢀallowableꢀlimitsꢀspeciﬁedꢀforꢀ

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.

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.

²Land pattern geometry is too small for silkscreen outline.

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%

relativeꢀhumidity.ꢀTemperatureꢀﬂuctuationsꢀshouldꢀbeꢀminimizedꢀtoꢀavoidꢀcondensationꢀonꢀtheꢀpartsꢀandꢀatmospheresꢀshouldꢀbeꢀfreeꢀofꢀ

chlorine and sulphur bearing compounds. For optimized solderability chip stock should be used promptly, preferably within three years

of receipt.

Although KEMET designs and manufactures its products to the most stringent quality and safety standards, given the current state of the art, isolated component failures may still

occur. Accordingly, customer applications which require a high degree of reliability or safety should employ suitable designs or other safeguards (such as installation of protective

circuitry or redundancies) in order to ensure that the failure of an electrical component does not result in a risk of personal injury or property damage.

Although all product–related warnings, cautions and notes must be observed, the customer should not assume that all safety measures are indicted or that other measures may not

be required.
