Array configuration.

DESCRIPTION

Production is strictly controlled and follows an extensive

set of instructions established for reproducibility. A homo-

geneous film of metal alloy is deposited on a super high

achieve the desired temperature coefficient. Specially

designed inner contacts are deposited on both sides. A

special laser is used to achieve the target value by smoothly

cutting a meander groove 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.

The result of the determined production is verified by an

extensive

testing

procedure

and

optical

inspection

performed on 100 % of the individual chip resistors. Only

accepted products are laid directly into the paper tape in

accordance with EN 60 286-3.

ASSEMBLY

The resistors are suitable for processing on automatic SMD

assembly systems and for automatic soldering using wave,

reflow or vapour phase. The encapsulation is resistant to all

cleaning solvents commonly used in the electronics industry,

including alcohols, esters and aqueous solutions. The

resistors are 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 compliance 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 Electronic Equipment

Directive (WEEE)

Solderability is specified for 2 years after production or

re-qualification. The permitted storage time is 20 years.

APPROVALS

Where applicable, the resistors are tested in accordance with

EN 140 401-801 (superseding CECC 40401-801) which

refers to EN 140 000 (EN 60 115-1) and EN 140 400

(IEC 60 115-8).
