FEATURES
DESCRIPTION
A homogeneous film of metal alloy is
deposited on a high grade ceramic
body. After a helical groove has been
cut in the resistive layer, tinned
connecting wires of electrolytic copper
or copper-clad iron are welded to the
end-caps. The resistors are coated with
a red, nonflammable lacquer which
provides electrical, mechanical and

climatic protection. This coating is not
resistant to aggressive fluxes. The
encapsulation is resistant to all
cleaning solvents in accordance with
“MIL-STD-202E, method 215”,
and

Ordering example
The ordering code for resistor type
PR02 with Cu leads and a value of
750
Ω
, supplied on a bandolier of
1000 units in ammopack, is:
2322 194 13751.
•
The resistors have a 12-digit
ordering code starting with 23.
•
The first 7 digits indicate the resistor
type and packaging;
see Tables 1 and 2.
•
The remaining 3 digits indicate the
resistance value:
– The first 2 digits indicate the
resistance value.
– The last digit indicates the
resistance decade in accordance
with Table 3.
