standard,

tin / lead available

• 8 mm, 12 mm tape and reel packaging

available

per

EIA

481

and

reeling

per

IEC 60286-3.

• 7" [178 mm] standard. 13" [330 mm] available

• Case code compatibility with EIA 535BAAC and CECC

30801

• All cases except R case are halogen-free

• Material categorization: for definitions of compliance

please see www.vishay.com/doc?99912

Note

* This datasheet provides information about parts that are

RoHS-compliant and / or parts that are non RoHS-compliant. For

example, parts with lead (Pb) terminations are not RoHS-compliant.

Please see the information / tables in this datasheet for details

Notes

• Preferred tolerances and reel sizes are in bold.

We reserve the right to supply higher voltage ratings and tighter capacitance tolerance capacitors in the same case size

• Low ESR solid tantalum chip capacitors allow delta ESR of 1.25 times the datasheet limits after mounting

PACKAGING

This is

expressed in pF.

The first two digits

are the significant

figures. The third

is the number

of zeros to follow.

X0 = ± 20 %

X9 = ± 10 %

This is expressed in V.

To complete the three-digit

block, zeros precede the

voltage rating. A decimal

point is indicated by an “R”

(6R3 = 6.3 V).
