High Precision Thin Film Chip Resistors

± 0.05 %; ± 5 ppm/K

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

desired temperature coefficient. Specially designed inner

contacts are deposited on both sides. A special laser is used

to achieve the target value by smoothly fine trimming the

resistive layer without damaging the ceramics. A further

conditioning is applied in order to stabilize the trimming

result. 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 on 100 % of the individual

chip resistors. Only accepted products are laid directly into

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. The immunity of the

plating against tin whisker growth has been proven under

extensive testing.

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)

• 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.
