Note

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
grade ceramic body (Al
2
O
3
) and conditioned to achieve the
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
IEC 61760-1
(1)
. 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.
