Current Sense Resistors Add New 0402 Package Size

KOA Speer Electronics expands its SR73-RT Series of low-resistance anti-sulfuration current sense resistors with the SR731E-RT in a 0402-package size. The SR731E-RT will be available in ±1%, ±2%, and ±5% tolerances with resistance values from 1Ω up to 10 Ω, a power rating of 1/8 Watt and an operating temperature of -55°C to +155°C.


The resistors boast excellent anti-sulfuration characteristics due to the use of a special high sulfuration proof inner top electrode material and are designed for use in harsh environments with a high level of sulfur contamination. They are viable for use in outdoor environment applications in mining, agriculture, wine making, and oil/gas. It is also an excellent choice for use in automotive electronics and factory automation.
