SR73-RT Anti-Sulfur Flat Chip Resistors

KOA Speer SR73-RT Anti-Sulfur Flat Chip Resistors are current detecting resistors suitable for power supply and motor circuits. These resistors include a protective layer that acts as an anti-sulfur barrier and strengthens the electrode with a sulfur-resistant material. The SR73-RT resistors deliver low resistance values from 0.43Ω to 10Ω and are suitable for both flow and reflow soldering. These chip resistors are available in a range of sizes from 0603 to 1210 in ±1%, ±2%, and ±5% tolerances. The SR73-RT resistors are AEC-Q200 qualified and offer up to 0.6W power rating with a -55°C to +155°C operating temperature range. The KOA Speer SR73-RT Anti-Sulfur Flat Chip Resistors are ideal for use in outdoor applications, automotive electronics, and factory automation.
