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

coefficient. Nickel plated steel termination caps are firmly

pressed on the metallized rods. A special laser is used to

achieve the target value by smoothly cutting a non helical

pattern with a resulting low inductance 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 pure matte tin on nickel plating. Four or five

color code rings designate the resistance value and

The result of the determined production is verified by an

extensive testing procedure performed on 100 % of the

individual resistors. Only accepted products are laid directly

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

.

ASSEMBLY

The resistors are suitable for processing on automatic SMD

assembly systems. They are suitable for automatic

soldering using wave, reflow or vapor phase as shown in

. 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, potting compounds,

and their processes, if applied, shall be qualified by

appropriate means to ensure the long-term stability of the

whole system.

The resistors are completely lead (Pb)-free, 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, however,

excellent solderability is proven after extended storage in

excess of 10 years. The permitted storage time is 20 years.

The immunity of the plating against tin whisker growth has

been proven under extensive testing.
