## **Small Signal Diode** 

## **52mm Taping Specification** 

1. T and A indicates axial tape and ammo packing (52mm tape spacing). 

2. 300mm (minimum) leader tape on every spool. 

3. Number of empty places allowed 0.25% without consecutive empty places. 

4. Ends of leads shall preferably not protrude beyond the tapes. 

5.  Components shall be held sufficiently in the tape or tapes so that they can not come free in normal handling.
