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 % Al

) and conditioned to

achieve the desired temperature coefficient. Nickel plated

steel termination caps are firmly pressed on the metallized

rods. Special laser devices are used repeatedly to achieve

the target value by slowly and smoothly cutting a helical

groove in the resistive layer without damaging the ceramics.

A further conditioning is applied in order to stabilise the

trimming result. Connecting wires of electrolytic copper

plated with 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. Script

marking designates the resistance value plus coded TCR

and tolerance.

The result of the determined production is verified by an

accelerated aging (burn-in) and 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.

MATERIALS

Vishay acknowledges the following systems for the

regulation of hazardous substances:

• IEC 62474, Material Declaration for Products of and for the

Electrotechnical Industry, with the list of declarable

substances given therein

(1)

• The Global Automotive Declarable Substance List

(GADSL)

(2)

• The REACH regulation (1907/2006/EC) and the related list

of substances with very high concern (SVHC)

(3)

for its

supply chain

The products do not contain any of the banned substances

as per IEC 62474, GADSL, or the SVHC list, see

www.vishay.com/how/leadfree.

Hence the products fully comply with the following

directives:

• 2000/53/EC End-of-Life Vehicle Directive (ELV) and

Annex II (ELV II)

• 2011/65/EU Restriction of the Use of Hazardous

Substances

Directive

(RoHS)

with

amendment

2015/863/EU

• 2012/19/EU Waste Electrical and Electronic Equipment

Directive (WEEE)

Vishay pursues the elimination of conflict minerals from its

supply chain, see the Conflict Minerals Policy at

www.vishay.com/doc?49037.

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 suitability of conformal coatings, if applied, shall be

qualified by appropriate means to ensure the long-term

stability of the whole system. 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.

APPROVALS

Where applicable, the resistors are tested in accordance to

EN 60115-1

and

EN 140100.

Vishay

Beyschlag

has

achieved

“Approval

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
