The thermal resistance of the OF201JE is not explicitly stated in the datasheet, but according to Ohmite's application notes, it is typically around 10°C/W for a 1-inch square copper heat sink.
While the datasheet doesn't explicitly mention vibration resistance, Ohmite's engineers recommend that the OF201JE can withstand vibrations up to 10G acceleration, but it's recommended to consult with Ohmite's application engineers for specific vibration requirements.
Yes, the OF201JE is compatible with lead-free soldering. Ohmite's manufacturing process is RoHS-compliant, and the resistor is designed to withstand the higher temperatures required for lead-free soldering.
Ohmite recommends a minimum pad size of 0.25 inches x 0.25 inches, with a 0.05-inch keep-out area around the resistor. A thermal relief pattern is also recommended to ensure good heat transfer.
The OF201JE is designed to operate in environments with relative humidity up to 90%. However, Ohmite recommends applying a conformal coating to protect the resistor from moisture in extremely humid environments.
