light blue protective coating designed for electrical,
mechanical and climatic protection. Four or five colour
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.
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 resistors are completely lead-free, the pure tin plating
provides compatibility with lead-free 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.
The resistors are tested in accordance with
CECC 40101-806
which refers to
EN 60115-1
and
EN 140100.
Approval of conformity is indicated by the
CECC logo on the package label.
BCcomponents BEYSCHLAG has achieved
"Approval of
Manufacturer"
in accordance with
EN 100114-1.
This product family of leaded thin film resistors for
professional applications is complemented by
Zero Ohm
Jumpers
and
isolators.
On request, resistors are available with established
reliability in accordance with
CECC 40101-806 Version E.
Please refer to the special data sheet for information on
failure rate level, available resistance ranges and ordering
codes.

DESCRIPTION
MBA 0204, MBB 0207 and MBE 0414 professional leaded
thin film resistors are the general purpose resistor for all
fields of professional electronics where reliability and
stability is of major concern. Typical applications include
industrial, telecommunication and medical equipment.
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

O

) 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

ORDERING INFORMATION
MBA 0204; MBB 0207;
MBE 0414
Components may be ordered by using either a simple clear text ordering code, see “Type description and ordering code”
or BCcomponents’ unique 12NC.
Numeric Ordering code (12NC)
•
The resistors have a 12-digit ordering code starting with 2312.
•
The subsequent 4 digits indicate the resistor type, specification and packaging; see Table 2.
•
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 Table 3.
