Precision Resistor Networks
SR01&
S1 Series
The
SR01
& S1 Series resistor networks are precision-class metal film components featuring tight resistance
tolerance and low values of temperature coefficient of resistance (TCR). This resistor network package
provides both excellent resistance ratio and TCR tracking.

Packaging Materials
Packaging Requirements
Labeling Requirements
Not drawin to scale.
Carrier tape part #: TSSOP-08
Cover tape part #: Vendor determined.
Reel size: 7 or 13 inch - Quantity dependent.
All taping done in accordance with EIA 481
standards.
Pieces taped with the marking up and showing
through the cover tape (as shown in the above
drawing).
All orders under 100pcs, will be put on cut tape
only with no leader or trailer.
Labels will contain the TFT taped part number
and quantity of pieces taped.
Refer to the TFT Taped Part Numbering section
for part numbers.
