The thermal resistance of the 45FR30E is typically around 10°C/W, but this can vary depending on the specific application and mounting method. It's recommended to consult with Ohmite's technical support or application notes for more information.
The 45FR30E is a wirewound resistor, which can exhibit inductive behavior at high frequencies. While it can be used in high-frequency applications, it's not the most ideal choice. Ohmite recommends using their non-inductive resistors, such as the FRF series, for high-frequency applications above 100 kHz.
The 45FR30E is designed to withstand moderate vibration, but it's not recommended for extreme vibration environments. Ohmite recommends using their resistors with a higher vibration rating, such as the VHF series, for applications that require high vibration resistance.
Yes, the 45FR30E is RoHS and REACH compliant, meeting the requirements for lead-free and hazardous substance-free materials. Ohmite provides documentation and certification for compliance upon request.
Ohmite recommends derating the 45FR30E by 1% for every 1°C above 25°C. For example, at 50°C, the resistor should be derated by 25%. This ensures reliable operation and prevents overheating.
