Components may be ordered by using either a simple clear
text ordering code, see “Type Description and Ordering
Code” or Vishay BCcomponents’ unique 12NC.
Numeric Ordering Code (12NC)
•
The resistors have a 12-digit Part Number starting with
2312.
•
The subsequent 4 digits indicate the resistor type,
specification and packaging; see the 12NC Part Number
table.
•
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 the 12NC Indicating Resistance

DESCRIPTION
Production is strictly controlled and follows an extensive set
of instructions established for reproducibility. A
homogeneous film of metal alloy is deposited on a high grade
ceramic body (85 % Al
2
O
3
) and conditioned to achieve the
desired temperature coefficient. Nickel plated steel
termination caps are firmly pressed on the metallized rods.
Special laser devices are used repeatedly to achieve the
target value by slowly and smoothly cutting a helical groove
in the resistive layer without damaging the ceramics. A
further conditioning is applied in order to stabilise the
trimming result. Connecting wires of electrolytic copper
plated with pure tin are welded to the termination caps. The
resistors are covered by protective coating designed for
electrical, mechanical and climatic protection.The
terminations receive a final pure tin on nickel plating. Script
marking designates the resistance value plus coded TCR
and tolerance.
The result of the determined production is verified by an
accelerated ageing (burn-in) and extensive testing
procedure performed on 100 % of the individual resistors.
Only accepted products are stuck directly on the adhesive
tapes in accordance with
IEC 60286-1.
Document Number: 28726
Revision: 21-Aug-07
ASSEMBLY
The resistors are suitable for processing on automatic
insertion equipment and cutting and bending machines.
Excellent solderability is proven, even after extended
storage. They are suitable for automatic soldering using
wave or dipping. The encapsulation is resistant to all
cleaning solvents commonly used in the electronics industry,
including alcohols, esters and aqueous solutions. The
suitability of conformal coatings, if applied, shall be qualified
by appropriate means to ensure the long-term stability of the
whole system.
APPROVALS
Where applicable, the resistors are tested in accordance with
CECC 40101-806
which refers to
EN 60115-1
and
EN 140100.
Vishay BEYSCHLAG has achieved
