Notes
• MB_ series has been merged with the related SMA series to form one series “MB_/SMA__”
• These resistors do not feature a limited lifetime when operated within the permissible limits. However, resistance value drift increasing over
operating time may result in exceeding a limit acceptable to the specific application, thereby establishing a functional lifetime.

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 and conditioned to achieve the desired
temperature coefficient. Plated steel termination caps are
firmly pressed on the metallized 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.
A further conditioning is applied in order to stabilise the
trimming result. Connecting wires of electrolytic copper
plated with 100 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. Four or
five color code rings designate the resistance value and
tolerance in accordance with
IEC 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
IEC 60286-1; IEC 60286-2.

on the package label for CECC version.
Vishay BEYSCHLAG has achieved
“Approval of
Manufacturer”
in accordance with
IEC QC 001002-3,
clause 2.
The release certificate for
“Technology Approval
Schedule”
in accordance with
CECC 240001
based on
IEC QC 001002-3,
clause 6 is granted for the Vishay
BEYSCHLAG manufacturing process.
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
GADSL
(2)
and
the
CEFIC-EECA-EICTA
(3)
list of legal restrictions on
hazardous substances. This includes full compliance with
the following directives:
