1000 pieces packaging quantity is only available for precision resistors with tolerance ± 0.1 %.

DESCRIPTION

The 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

desired temperature coefficient. A special laser is used to

achieve the target value by smoothly cutting an appropriate

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 tin-lead (SnPb) on nickel

plating. The result of the determined production is verified

by an extensive testing procedure performed on 100 % of

the individual resistors. Only accepted products are placed

into the tape in accordance with IEC 60286-3, Type I.

Resistance marking is not applied on TNPW0402.

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

. Solderability is specified for 2 years after

production. The permitted storage time is 20 years.

The terminations are plated with SnPb solder, controlled for

a minimum lead Pb content of 6 % for compliance with the

respective requirements of Bellcore, MIL and ESCC

specifications.

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.
