DIMENSIONS
Note:
• Color code marking is applied according to EN 60062 in five bands (E96 or E192 series). Each color band appears as a single solid line, voids
are permissible if at least 2/3 of the band is visible from each radial angle of view. The last color band for tolerance is approximately 50 % wider
than the other bands. An interrupted violet band between the 1st and 2nd full band indicates the failure rate level E7. An interrupted orange
band between the 4th and 5th full band indicates the temperature coefficient of 15 ppm/K.
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 % Al2O3) and conditioned to achieve the
desired temperature coefficient. Nickel plated steel
termination caps are firmly pressed on the metallised rods. A
special laser is used to achieve the target value by smoothly
cutting a helical groove in the resistive layer without
damaging the ceramics. Connecting wires of electrolytic
copper plated with 100 % pure tin are welded to the
termination caps. The resistor elements are covered by a
light blue protective coating designed for electrical,
mechanical and climatic protection. Four or five color code
rings designate the resistance value and tolerance in
accordance with EN 60062.
The result of the determined production is verified by an
extensive testing procedure performed on 100 % of the
individual resistors. Only accepted products are stuck
directly
on the adhesive tapes in accordance with
EN 60286-1
.
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. The resistors are completely lead (Pb)-free,
the pure tin plating provides compatibility with lead (Pb)-free
and lead-containing soldering processes. The immunity of
the plating against tin whisker growth has been proven under
extensive testing.
All products comply with the CEFIC-EECA-EICTA list of legal
restrictions on hazardous substances.
This includes full compliance with the following European
RoHS directives:
•2000/53/EC End of Vehicle Life Directive (ELV)
•
2000/53/EC Annex II to End of Vehicle Life Directive (ELV II)
•2002/95/EC Restriction of the use of Hazardous
Substances Directive (RoHS)
•2002/96/EC Waste Electrical and Electronic Equipment
Directive (WEEE)
Solderability is specified for 2 years after production or
re-qualification. The permitted storage time is 20 years.
