The thermal resistance of the TWW3J2R0E is not explicitly stated in the datasheet, but according to Ohmite's general specifications for the TWW series, the thermal resistance is typically around 10-15°C/W.
While the TWW3J2R0E is a wirewound resistor, it's not specifically designed for high-frequency applications. Ohmite recommends their TF series for high-frequency applications. However, the TWW3J2R0E can still be used up to a few hundred kHz, but its performance may degrade above that frequency range.
The TWW3J2R0E has a maximum operating temperature of 250°C, but it's essential to derate the power rating accordingly. Ohmite provides a derating curve in the datasheet, which shows the maximum power rating at different temperatures. Always check the derating curve to ensure the resistor can handle the expected temperature and power conditions.
Yes, the TWW3J2R0E is RoHS (Restriction of Hazardous Substances) and REACH (Registration, Evaluation, Authorization, and Restriction of Chemicals) compliant, as stated in Ohmite's documentation and certifications.
Ohmite recommends a soldering temperature of 260°C (500°F) for 3-5 seconds, maximum. It's essential to follow proper soldering techniques and temperature control to avoid damaging the resistor.
