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.
