The thermal resistance of the 45F27RE is typically around 10°C/W, but it's recommended to consult Ohmite's application notes or contact their support for more specific information.
While the 45F27RE is a wirewound resistor, it's not optimized for high-frequency applications. Ohmite recommends using their high-frequency resistors, such as the HFC series, for frequencies above 100 kHz.
The 45F27RE is designed to withstand moderate vibration, but Ohmite recommends consulting their application notes or contacting their support for specific vibration testing and validation.
Yes, the 45F27RE is compatible with lead-free soldering processes, but Ohmite recommends following their recommended soldering profiles and procedures to ensure reliable assembly.
Ohmite recommends derating the power rating of the 45F27RE by 1% for every 1°C above 25°C. For example, at 50°C, the power rating would be derated by 25%.
