DESCRIPTION
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.

Ordering code (12NC)
•
The resistors have a 12-digit
ordering code starting with 2322
•
The subsequent four or five digits
indicate the resistor type and
packing; see Table 1.
•
The remaining digits indicate the
resistance value:
– The first 2 digits for 5% or
3 digits for 1% tolerance
products 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 or E96 series for resistors
with a tolerance of
±5%
or
±1%.
The values of the E24/E96
series are in accordance with
“IEC publication 60063”.
