The labeling is made at the packing unit only.
Any marking of single components is not available (only on request at individual cases).
Ordering data:
Type – value – tolerance – TCR
Example: HVM 50 10G
±10%
TCR 100
If no requirement for TCR is given, the standard value (highest value in table) will be supplied.
Standard measuring voltage is 10V (50V for values >1G). Different voltages on request and
agreement (specify explicitly).
