CTS Electronic Components S4x Sulfur Resistant Chip Resistor Arrays
CTS Electronic Components S4x Series Sulfur Resistant Chip Resistor Arrays are specifically designed to resist sulfurization that occurs in high-sulfur environments. The standard chip and chip array resistor products get corroded in high sulfurous environments and a layer of silver sulfide (Ag2S) is formed. This sulfide chemical can crack the ceramic substrate and create a very high resistance path between resistor connections to function as an open circuit connection. The design of S4x Series Chip Resistor Arrays adds a protective layer between the silver (Ag) conductor and final epoxy cover coat layer. This barrier prevents the fusion of sulfur into the silver interface avoiding sulfide growth.
