Example of sulfide disconnection and mechanism
Entering gas or oil containing sulfur from gap between
the protective coating and the electrode
Corrosion-disconnection top electrode made of silver
Example of sulfide disconnection
Grade of anti-sulfurated chip resistor
Depending on the difference in the corrosive environment,there are two kinds of the line-up, the gold electrode products (for industrial machinery applications) and silver-palladium alloy electrode products (for general use)
Sulfidation performance comparison of electrode
Anti-sulfurated chip resistors can be used from machine tools such as industrial applications, servers, base station, lightings, the infrastructure systems such as exposure often to ambient air.
