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 and low 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

and

optical

inspection

performed on 100 % of the individual chip resistors. This

includes full screening for the elimination of products with

potential risk of early field failures (feasible for R

 10 ).

Only accepted products are laid directly into the paper tape

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. 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 RoHS compliant, the pure tin plating

provides

compatibility

with

lead

(Pb)-free

and

lead-containing

soldering

processes.

Solderability

is

specified for 2 years after production or requalification. The

permitted storage time is 20 years. The immunity of the

plating against tin whisker growth has been proven under

extensive testing.

All

products

comply

with

the

GADSL

(1)

and the

CEFIC-EECA-EICTA

(2)

list

of

legal

restrictions

on

hazardous substances. This includes full compliance with

the following directives:

• 2000/53/EC End of Vehicle life Directive (ELV) an 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

the climatic category 55/125/56, which relates to the

“standard operation mode” of this datasheet.

Conformity is attested by the use of the CECC logo (

) as

the mark of conformity on the package label.
