The thermal resistance of the FSR03CE is not explicitly stated in the datasheet, but according to Ohmite's application notes, the thermal resistance from junction to case (RθJC) is approximately 1.5°C/W, and from case to ambient (RθCA) is approximately 10°C/W.
While the FSR03CE is primarily designed for low-frequency applications, it can be used in high-frequency applications up to 100 kHz with some caution. However, the inductance and capacitance of the resistor may affect its performance at high frequencies, and additional filtering or decoupling may be necessary.
The FSR03CE has a maximum operating temperature of 150°C, but it's recommended to derate the power rating above 125°C to ensure reliable operation. For high-temperature applications above 150°C, consider using a different resistor model or consulting with Ohmite's application engineers.
The FSR03CE is designed to withstand moderate vibration levels, but it's essential to ensure proper mounting and securing of the resistor to prevent mechanical stress. For extreme vibration environments, consider using a resistor with a more robust construction or consulting with Ohmite's application engineers.
Yes, the FSR03CE is RoHS (Restriction of Hazardous Substances) and REACH (Registration, Evaluation, Authorization, and Restriction of Chemicals) compliant, meeting the requirements for lead-free and hazardous substance-free components.
