Sulfuration-resistant Chip Resistors (TRR Series)


An original internal construction comprised of a sulfuration-resistant membrane is utilized that prevents sulfurated gas from penetrating, resulting in superior anti-sulfuration characteristics.

A broad lineup is available in a range of sizes, from 1005 to 3216. Jumper types are also available.
