Open-Air Sense Resistor

The OAR-TP Series of open-air sense resistors have reduced spacing between the leads compared to standard OAR Series devices.

The Series is rated for 1 and 3 W at 85°C with resistances from 0.005 to 0.1 Ω The device has a TCR as low as ±20 ppm/°C and inductance values in the single-digit nanoHenry range. Operating temperatures range from -40 to 125°C. A lead-free RoHS-compliant version is available.
