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 are welded to the end-caps.
The resistors are coated with a grey,
flame retardant lacquer which
provides electrical, mechanical, and
climatic protection. The
encapsulation is resistant to all
cleaning solvents in accordance with
鈥淢IL-STD-202E, method 215鈥?
and
鈥淚EC 60068-2-45鈥?.
ORDERING INFORMATION
Ordering code (12NC)
鈥?/div>
The resistors have a 12-digit
ordering code starting with 23
鈥?/div>
The subsequent 7 digits indicate
the resistor type and packaging;
see Table 1.
鈥?/div>
The remaining 3 digits indicate the
resistance values:
鈥?The first 2 digits indicate the
resistance value.
鈥?The last digit indicates the
resistance decade in
accordance with Table 2.
