Packaging
All types in the YQ range are available loose-packed,
as shown in the drawing. Devices are also available on
bandolier (tape & reel): types with diameter A<12mm
comply with IEC 286-2. To identify the tape & reel packaging
required, replace N in the product codes shown in the table
as follows:
