DESCRIPTION

Ω

The resistors are constructed on a high grade ceramic body (aluminium
oxide). Internal metal electrodes are added at each end and connected by
a resistive paste which is applied to the top surface of the substrate. The
composition of the paste is adjusted to give the approximate resistance
required and the value is trimmed to within tolerance by laser cutting of
this resistive layer.
The resistive layer is covered with a protective coating and printed with
the resistance value. Finally, the two external end terminations are added.
To guarantee optimum solderability the outer layer consists of a lead-tin
alloy.

resistor, value 1000
Ω
with
0.5% tolerance, supplied on paper
tape of 5000 units per reel is:
2390 411 61002.
Ordering code (12NC)
•
The resistors have a 12-digit
ordering code starting with 2390;
see Table 1.
•
The subsequent 4 digits indicate
the resistor type and packing.
•
The remaining 4 digits indicate
the resistance value:
−
The first 3 digits indicate the
resistance value.
−
The last digit indicates the
resistance decade in
accordance with Table 2.

FUNCTIONAL DESCRIPTION
Product characterization
Standard values of nominal
resistance are taken from the E24
and E96 series for resistors with a
tolerance of
±0.5%.
The values of the E24 and E96
series are in accordance with
“IEC publication 60063”.
