The thermal resistance of the PFR5K25R0E 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 application engineers for more detailed information.
The PFR5K25R0E is designed for general-purpose power resistors and may not be suitable for high-frequency applications above 100 kHz. For high-frequency applications, Ohmite recommends using their HF series resistors, which are specifically designed for high-frequency use.
The PFR5K25R0E has a maximum operating temperature of 150°C, but derating is required above 125°C. For high-temperature applications, Ohmite recommends using their high-temperature resistors, such as the PHT series, which are designed for use up to 250°C.
The PFR5K25R0E is typically mounted using a screw or clip, and Ohmite recommends using a thermal interface material (TIM) to ensure good thermal contact between the resistor and the heat sink. Consult Ohmite's application notes for more detailed mounting recommendations.
Yes, the PFR5K25R0E is RoHS compliant and meets the requirements of the European Union's Restriction of Hazardous Substances (RoHS) directive.
