STANDARD REEL PACKAGING INFORMATION
1. Component Leads:
f. A row of components must be centered between tapes
0.047" (1.19 mm). In addition, individual components
a. Component leads shall not be bent beyond 0.047"
(1.19 mm) maximum from their nominal position when
measured from the leading edge of the component lead
at the inside tape edge and at the lead egress from the
component.
b. The “C” dimension shall be governed by the overall
length of the reel packaged component. The distance
between flanges shall be 0.125" to 0.250" (3.18 mm to

h. Quantity per reel shall be controlled so that tape
components and cover shall not extend beyond the
smallest dimension of the flange (either across flats or
diameter). Once the quantity per reel for each part
number has been established, future orders for that part
number shall be packaged in that quantity. When order or
release quantity is less than the established quantity, a
standard commercial pack is to be used.
2. Orientation:
a. All polarized components must be oriented to one
direction. The cathode lead tape shall be a color and the
anode lead tape shall be white.
3. Reeling:
a. Components on any reel shall not represent more than
two date codes when date code identification is required.
b. Component leads shall be positioned between pairs of
0.250" (6.35 mm) tape.
c. The disposable reels have hubs with corrugated
fibreboard flanges and core or equivalent.
d. A minimum of 12" (304.8 mm) leader of tape shall be
provided before the first and after the last component on
the reel.
e. 50 or 60 lb. Kraft paper must be wound between layer
of components as far as necessary for component
protection. Width of paper to be 0.062" to 0.250"
(1.57 mm to 6.35 mm) less than the “C” dimension of the
reel.
i. A maximum of 0.25 % of the components per reel
quantity may be missing without consecutive missing
components.
j. Adequate protection must be provided to prevent
physical damage to both reel and components during
shipment and storage.
4. Marking:
a. Minimum reel and carton marking shall consist of the
following: Customer Part Number, Purchase Order No.,
Quantity, Package Date, Manufacturer's name, Electrical
Value, Date Code, Vishay Sprague Part Number and
Country of Origin.
