Higher Power, Anti-Surge Resistors for Harsh Environments

April 09, 2020 by Paul Shepard

Panasonic has introduced the NEW ERJ-UP3 Series Anti-Sulfurated Thick Film Chip Resistors, Anti-Surge Type in an 0603-inch case size. Extremely durable in challenging or unclean, harsh environments, the NEW ERJ-UP3 Series provides anti-sulfurization characteristics that avoid an open circuit caused by a sulfide disconnection.

High resistance to sulfurization is achieved through the use of an anti-sulfurated electrode structure and material in the manufacture of ERJ-UP3 Series Resistors.

The ERJ-UP3 Series Resistors are recommended for design in harsh or unclean environment applications where a device might be exposed to oil, gas or polluted soil. The NEW ERJ-UP3 Series features higher rated power at 0.25W in a 0603 inch / 1608 mm case size and ESD surge characteristics superior to standard thick Film Resistors.

AEC-Q200 Compliance and IEC 60115-8, JIS C 5201-8 and JEITA RC-2134C Reference Standards for the entire ERJ-UP3 Series of Anti-Sulfulrated Thick Film Chip Resistors from Panasonic ensures optimal quality and reliability.
