SR731E-RT (0402 Anti-Sulfur) Current Sensing Chip Resistors

KOA Speer's SR73-RT series is designed for use in harsh environments with a high level of sulfur contamination

Image of KOA's SR731E-RT Current Sensing Chip Resistor KOA Speer Electronics has expanded its SR73-RT series of low-resistance anti-sulfuration current sense resistors with a 0402 package size. The SR731E-RT series is available in ±1%, ±2%, and ±5% tolerances with resistance values from 1 Ω up to 10 Ω, a power rating of 1/8 W, and an operating temperature range of -55°C to +155°C.

SR73-RT series current sense resistors offer 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.

The SR731E-RT current sense resistors are ideal for use in outdoor environment applications in mining, agriculture, winemaking, and oil/gas. They are also an excellent choice for use in automotive electronics and factory automation. These resistors are AEC-Q200 qualified.
