L = Length, B = Width, D = Thickness (Tolerance of dimensions: ± 0.5 mm)
d = Standard wire diameter (in mm), other diameters possible
R
Ød
R = Standard lead spacing (other spacing possible by bending)
Packaging:
Bulk in plastic bags
Minimum quantity: 100 pieces per value
Ordering Data:
Type – value – tolerance – TCR
Example: GST 4020 10G ±10% TCR 100
Untrimmed parts are indicated by the extension “NA” in the order code:
Type – value – tolerance – NA – TCR - packaging
Example: GST 4020 10G ±10% NA 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).
