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

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.

For the high ohmic range, optimized cermet products provide

comparable properties. 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 performed on 100 % of the

individual resistors. This includes pulse load screening for

the elimination of products with a potential risk of early life

failures according to EN 140401-801, 2.1.2.2 (feasible for

R

 10 ). Only accepted products are laid directly into the

Products within a packaging unit are from the same

production lot and carry the same date code.

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

production or requalification. The permitted storage time is

20 years.

The resistors are RoHS compliant; 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.

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.

All

products

comply

with

the

and

the

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)

 2011/65/EU Restriction of the use of Hazardous

Substances directive (RoHS)

 2002/96/EC Waste Electrical and Electronic Equipment

Directive (WEEE)

APPROVALS

The resistors are approved within the IECQ-CECC Quality

Assessment System for Electronic Components to the detail

specification EN 140401-801 which refers to EN 60115-1,

EN 140400 and the variety of environmental test procedures

Conformity is attested by the use of the CECC logo (

) as

the mark of conformity on the package label.

Vishay

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,
