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 resistors are covered by protective
coating designed for electrical, mechanical and climatic
protection.The terminations receive a final pure tin on
nickel plating. Five colour code rings designate the
resistance value and tolerance in accordance with
IEC 60 062.
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 60 286-1.
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.
Where applicable, the resistors are tested in accordance
with
CECC 40 101-806
which refers to
EN 60 115-1
and
EN 140 100.

Industrial equipment.
DESCRIPTION
CBB 0207 leaded resistors with advanced pulse load
capability, are the perfect choice for circuitries exposed to
high levels of electromagnetic interference or electrostatic
discharge. The resistors can also be used to protect the
circuitry of signal and mains input lines from surge pulses.
Applications are in all fields of automotive,
telecommunication and industrial equipment.
Production is strictly controlled and follows an extensive set
of instructions established for reproducibility. A
homogeneous and dense carbon film is deposited on a high
grade ceramic body (85% Al

) and conditioned to
achieve the desired temperature coefficient. Nickel plated
steel termination caps are firmly pressed on the rods. A
special laser is used to achieve the target value by smoothly
BCcomponents BEYSCHLAG has achieved
"Approval of
Manufacturer"
in accordance with
EN 100 114-1.

ORDERING INFORMATION
CBB 0207
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.
