KOA Speer Introduces 0402 Size in Low Ohm Anti-Sulfur SR73-RT Series Current Sense Resistors

Bradford, PA - February 4, 2019 - KOA Speer Electronics has expanded its SR73-RT Series of Low Resistance Anti-Sulfuration Current Sense Resistors with a new 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.

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 resistor is ideal 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.

These resistors are AEC-Q200 qualified. Lead time is 10 weeks. Please contact KOA Speer Electronics for samples or additional information.
