Note: 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.
1) The power dissipation on the resistor generates a temperature rise against the local ambient, depending on the heatflow support of the
printed-circuit board (thermal resistance). The rated dissipation applies only if the permitted film temperature is not exceeded. Furthermore, a
high level of ambient temperature or of power dissipation may raise the temperature of the solder joint, hence special solder alloys or board
materials may be required to maintain the reliability of the assembly.

Vishay Beyschlag
DESCRIPTION
APPROVALS
Production of the CMA 0204 HF speciality MINI-MELF
resistor 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 ꢀ Al2O3). Nickel plated steel termination caps are
firmly pressed on the coated rods. A special laser is used to
achieve the target value by smoothly cutting a non helical
pattern with a resulting low inductivity in the resistive layer
without damaging the ceramics. The resistor elements are
covered by a protective coating designed for electrical,
mechanical and climatic protection.The terminations receive
a final pure tin on nickel plating. Four color code rings
designate the resistance value and tolerance in accordance
with IEC 60062*.
Where applicable the resistors are tested in accordance with
EN 140401-803 which refers to EN 60115-1, EN 140400 and
the variety of enviromental text procedures of the IEC 60068*
series.
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.
Note:
* The quoted IEC standards are also released as EN standards with
the same number and identical contents.
The result of the determined production is verified by an
extensive testing procedure performed on 100 ꢀ of the
individual resistors. Only accepted products are laid directly
into the blister tape in accordance with IEC 60286-3*.
ASSEMBLY
The resistors are suitable for processing on automatic
SMD assembly systems. They are suitable for automatic
soldering using wave, reflow or vapour phase as shown in
IEC 61760-1*. Excellent solderability is proven, even after
extended storage in excess of 10 years. 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
soldering processes. The immunity of the plating against tin
whisker growth has been proven under extensive testing.
All products comply with the GADSL1) and the CEFIC-
EECA-EICTA2) list of legal restrictions on hazardous
substances. This includes full compliance with the following
directives:
•
2000/53/EC End of Vehicle life Directive (ELV) and the
Annex II (ELV II)
• 2002/95/EC Restriction of the use of Hazardous
Substances Directive (RoHS)
• 2002/96/EC Waste Electrical and Electronic Equipment
Directive (WEEE)
