Vishay Beyschlag
MBA/SMA 0204 HF leaded thin film resistors for RF
applications are the perfect choice in high frequency circuit
designs; where the impedance change due to the parasitic
inductance of regular and professional resistors can not
be accepted. Typical applications are in the fields of
telecommunication equipment and industrial electronics.

Vishay Beyschlag High Frequency (> 3 GHz) Leaded Resistors
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 low-inductivity non-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. Four colour code rings designate the resistance
value and tolerance in accordance with IEC 60062.
Additional black dots near the 3rd colour ring identify the
special HF product.
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.
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
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 compatibility with the following
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 Electrical Equipment
Directive (WEEE)
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 “Approval of
Manufacturer” in accordance with EN 100114-1.

under standard atmospheric conditions in accordance with
IEC 60068-1, 5.3. Climatic category LCT/UCT/56 (rated
temperature range: Lower Category Temperature, Upper
Category Temperature; damp heat, long term, 56 days) is
valid.
Unless otherwise specified the following values apply:
Temperature: 15 °C to 35 °C
Relative humidity: 45 % to 75 %
Air pressure: 86 kPa to 106 kPa (860 mbar to 1060 mbar).
For testing the components are mounted on a test board in
accordance with IEC 60115-1, 4.31 unless otherwise
specified.
