The thermal resistance of the TKH45P47R0FE-TR is not explicitly stated in the datasheet, but according to Ohmite's general specifications, the thermal resistance (Rth) for this series is typically around 10-15°C/W.
While the TKH45P47R0FE-TR is a high-power resistor, its frequency response is not explicitly stated in the datasheet. However, Ohmite's thick-film resistors like the TKH45P47R0FE-TR are generally suitable for frequencies up to 100 kHz. For higher frequencies, it's recommended to consult with Ohmite's application engineers or consider alternative components.
The TKH45P47R0FE-TR is rated for operation up to 155°C, but its power rating derates above 125°C. For high-temperature applications, it's essential to consider the resistor's power derating and potential thermal runaway risks. Consult Ohmite's application notes or contact their support team for guidance on high-temperature usage.
While the TKH45P47R0FE-TR is a high-quality resistor, it may not meet the specific requirements for high-reliability or aerospace applications. Ohmite offers specialized resistors for these markets, such as their MIL-PRF-55342-qualified resistors. For critical applications, it's recommended to consult with Ohmite's application engineers to determine the best component for the specific use case.
The TKH45P47R0FE-TR is not specifically designed for high-humidity environments. However, Ohmite's thick-film resistors are generally resistant to humidity. If you plan to use the TKH45P47R0FE-TR in a humid environment, consider applying a conformal coating or consulting with Ohmite's application engineers for guidance on environmental protection.
