RC0805JR-070RL

RC0805JR-070RL is a low-value current-sense resistor in an 0805 SMD package. Its nominal resistance is 0.070 Ω (70 milliohms), with a low-inductance variant (the “L” suffix) for better high-frequency performance. It’s used to measure load current by producing a small voltage drop across the part.
Key points:
- Package: 0805 (about 2.0 x 1.25 mm)
- Value: ~0.070 Ω
- Tolerance: typically around ±5% (check the datasheet)
- Power rating: ~0.125 W (typical for 0805; actual current depends on board copper and ambient temperature)
- Applications: DC-DC converters, motor drivers, battery-management circuits, any place you need a precise current sense
Usage tip: place it in series with the load and read the differential voltage across it with a sense amplifier or ADC.
For exact specs (tolerance, TCR, max current, voltage rating, operating temp), consult the RC0805JR-070RL datasheet from the manufacturer.

Here are the key features of RC0805JR-070RL:
