Note
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.
2. Specified power rating requires dedicated heat-sink pads.

Note
1. Color code marking is applied according to IEC 60062 in four bands (E24 series) or five bands (E96 series). Each colour band appears as a
single solid line, voids are permissible if at least 2/3 of the band is visible from each radial angle of view. The last color band for tolerance is
approx, 50% wider than the other bands. An interrupted band between the 3rd and 4th full band identifies the special high frequency type.

High Frequency MELF Resistors
Vishay Beyschlag
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
(85 % Al
2
O
3
, for MICRO-MELF: 96 % Al
2
O
3
) ceramic body
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 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 or five 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.
APPROVALS
Where applicable the resistors are tested in accordance with
EN 140401-803
(superseding
CECC 40401-803)
which
refers to
EN 60115-1, EN 140400
and the variety of
enviromental test procedures of the
IEC 60068
series.
Vishay
BEYSCHLAG
has
achieved
"Approval
of
Manufacturer"
in accordance with
EN 100 114-1.
The
release certificate for
“Technology Approval Schedule”
in
accordance with
CECC 240001
based on
EN 100114-6
is
granted for the Vishay BEYSCHLAG manufacturing process.
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
or bulk
case in accordance with
IEC 60286-6
.
ASSEMBLY
The resistors are suitable for processing on automatic SMD
assembly systems. They are suitable for automatic soldering
using wave, reflow or vapour phase. 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
CEFIC-EECA-EICTA list of legal restrictions on hazardous
substances. This includes full compatibility with European
RoHS directive.
