Tape and Reel Specifications: all case sizes are
available on plastic embossed tape per EIA-481.
Standard reel diameter is 7" [178 mm].
Notes
• Metric dimensions will govern. Dimensions in inches are rounded and for reference only.
(1) A0, B0, K0, are determined by the maximum dimensions to the ends of the terminals extending from the component body and / or the body
dimensions of the component. The clearance between the ends of the terminals or body of the component to the sides and depth of the
cavity (A0, B0, K0) must be within 0.002" (0.05 mm) minimum and 0.020" (0.50 mm) maximum. The clearance allowed must also prevent
rotation of the component within the cavity of not more than 20°.
(2) Tape with components shall pass around radius “R” without damage. The minimum trailer length may require additional length to provide
“R” minimum for 12 mm embossed tape for reels with hub diameters approaching N minimum.
(3) This dimension is the flat area from the edge of the sprocket hole to either outward deformation of the carrier tape between the embossed
cavities or to the edge of the cavity whichever is less.
(4) This dimension is the flat area from the edge of the carrier tape opposite the sprocket holes to either the outward deformation of the carrier
tape between the embossed cavity or to the edge of the cavity whichever is less.
(5) The embossed hole location shall be measured from the sprocket hole controlling the location of the embossement. Dimensions of
embossement location shall be applied independent of each other.
(6) B1 dimension is a reference dimension tape feeder clearance only.
