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:
