Tape and Reel Dimensions (all dimensions in millimeters)

Carrier tape basic dimensions are based on EIA 481. The pocket is designed to hold the part for shipping and loading onto SMT

manufacturing equipment, while protecting the body and the solder terminals from damaging stresses. The individual pocket

design can vary from vendor to vendor, but width and pitch will be consistent.

Carrier tape is wound or placed onto a shipping reel 178 mm (7 inches) in diameter. The center hub design is large enough to

ensure the radius formed by the carrier tape around it does not put unnecessary stress on the parts.

Prior to shipping, moisture sensitive parts (MSL Level 2a-5a) are baked and placed into the pockets of the carrier tape. A cover

tape is sealed over the top of the entire length of the carrier tape. The reel is sealed in a moisture barrier ESD bag with the

appropriate units of desiccant and a humidity indicator card, which is placed in a cardboard shipping box. It is important to

note that unused moisture sensitive parts need to be resealed in the moisture barrier bag. If the reels exceed the exposure

limit and need to be rebaked, most carrier tape and shipping reels are not rated as bakeable at 125°C. If baking is required,

devices may be baked according to section 4, table 4-1, column 8 of Joint Industry Standard IPC/JEDEC J-STD-033.

Table 1 provides useful information for carrier tape and reels used for shipping the devices described in this document.
