Failure rate

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.

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

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.

APPROVALS

DESCRIPTION

Production is strictly controlled and follows an extensive

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.

set of instructions established for reproducibility.

homogeneous film of metal alloy is deposited on a high grade

(85 % Al₂O₃, for MICRO-MELF: 96 % Al₂O₃) 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 color 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.

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* 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 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

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)
