Note on Failure Rates: Exponential failure rate levels M, P, R, and S are inactive for new design per MIL-PRF-55365. Parts qualified to Weibull
failure rate levels are substitutable for exponential failure rate levels. Note: ESR limits are per MIL-PRF-55365/8.

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
Peel Strength
8 mm
0.1 Newton to 1.0 Newton (10g to 100g)
12 mm
0.1 Newton to 1.3 Newton (10g to 130g)
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. Reel Sizes:
Molded tantalum capacitors are available on either 180 mm (7") reels (standard) or 330 mm (13")
reels (with C-7280). Note that 13” reels are preferred.
4. Labeling:
Bar code labeling (standard or custom) shall be on the side of the reel opposite the sprocket holes.
Refer to EIA-556.

NOTES
1. B1 dimension is a reference dimension for tape feeder clearance only.
2. 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.
3. Tape with components shall pass around radius “R” without damage (see sketch A). The minimum trailer length (Fig. 2) may require
additional length to provide R min. for 12 mm embossed tape for reels with hub diameters approaching N min. (Table 2)
4. The cavity defined by A
0
,
B
0
,
and K
0
shall be configured to surround the part with sufficient clearance such that the chip does not pro-
trude beyond the sealing plane of the cover tape, the chip can be removed from the cavity in a vertical direction without mechanical
restriction, rotation of the chip is limited to 20 degrees maximum in all 3 planes, and lateral movement of the chip is restricted to 0.5 mm
maximum in the pocket (not applicable to vertical clearance.)
