Tantalum Surface Mount Capacitors – Standard Tantalum

T490 Series Commercial Grade MnO₂

Overview

The KEMET T490 Series, designed for customer product

applications (low temperature demanding applications),

meets RoHS compliance with leads constructed of 100%

matte tin and green molding compound. This series is

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 ESR value may increase up to 1.5 x Initial Limit post mounting

The DCL value may increase up to 2.0 x Initial Limit post mounting

Higher voltage ratings and tighter tolerance product including ESR may be substituted within the same size at KEMET's option. Voltage substitution will

be marked with the higher voltage rating. Substitutions can include better than series.

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.

Using the P max of the device, the maximum allowable rms

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).

¹Height of these chips may create problems in wave soldering.

²Land pattern geometry is too small for silkscreen outline.

Hand soldering should be performed with care due to the

difﬁcultyꢀinꢀprocessꢀcontrol.ꢀIfꢀperformed,ꢀcareꢀshouldꢀbeꢀ

taken to avoid contact of the soldering iron to the molded

case. The iron should be used to heat the solder pad, applying

solderꢀbetweenꢀtheꢀpadꢀandꢀtheꢀtermination,ꢀuntilꢀreﬂowꢀ

occurs.ꢀOnceꢀreﬂowꢀoccurs,ꢀtheꢀironꢀshouldꢀbeꢀremovedꢀ

immediately. “Wiping” the edges of a chip and heating the top

surface is not recommended.

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

storageꢀhumidityꢀnotꢀexceedꢀ60%ꢀrelativeꢀhumidity.ꢀTemperatureꢀﬂuctuationsꢀshouldꢀbeꢀminimizedꢀtoꢀavoidꢀcondensationꢀonꢀ

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 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. 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.

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
