The thermal resistance of the TUW5JR47E is not explicitly stated in the datasheet, but according to Ohmite's general specifications for the TUW series, the thermal resistance is typically around 10-15°C/W.
While the TUW5JR47E is a wirewound resistor, it's not specifically designed for high-frequency applications. Ohmite recommends their TF series for high-frequency applications. However, the TUW5JR47E can still be used up to a few hundred kHz, but its performance may degrade above that frequency range.
The TUW5JR47E is a wirewound resistor with a ceramic core, which makes it relatively robust against vibrations. However, it's essential to ensure proper mounting and secure the resistor to prevent mechanical stress. Ohmite recommends following their mounting guidelines to ensure reliable operation in high-vibration environments.
Yes, the TUW5JR47E is compatible with lead-free soldering processes. Ohmite's resistors are designed to meet the requirements of the RoHS directive, and they can withstand the higher temperatures associated with lead-free soldering.
Ohmite provides a general derating curve for their TUW series resistors, which recommends reducing the power rating by 1.5% per degree Celsius above 25°C. However, it's essential to consult the datasheet and Ohmite's application notes for specific guidance on derating the TUW5JR47E.
