Additional CV matching capability:
Zetex recognise that some applications ie filtering in digital audio receiver circuits, require these dual varactors
tobeverytightlymatched.Tomeetthisrequirementdevicescanbesuppliedtestedintocapacitancebandsatthe
2V condition.
Each(TA)reelwillcontain3000devicescarryingonlydiodestestedintoasinglebandandeachdevicewillhavea
partmark identifying the capacitance band which they meet.
As this is a final test measurement customers will not have the option to specify a capacitance at the time of
ordering and will be obliged to accept the band into which the devices are tested.
