TKH45P20R0FE-TR - Ohmite

TKH45P20R0FE-TR Frequently Asked Questions (FAQs)

• What is the thermal resistance of the TKH45P20R0FE-TR?
  The thermal resistance of the TKH45P20R0FE-TR is typically around 10°C/W, but this value can vary depending on the specific application and mounting method. It's recommended to consult with Ohmite's technical support or refer to the manufacturer's application notes for more information.
• Is the TKH45P20R0FE-TR resistor suitable for high-frequency applications?
  The TKH45P20R0FE-TR is a thick-film resistor, which can exhibit some high-frequency limitations. While it can be used in high-frequency applications, it's not the best choice. Ohmite recommends using their thin-film resistors, such as the HVC series, for high-frequency applications above 100 MHz.
• Can I use the TKH45P20R0FE-TR in a high-temperature environment?
  The TKH45P20R0FE-TR has a maximum operating temperature of 150°C. While it can tolerate high temperatures, it's essential to derate the power according to the temperature derating curve provided in the datasheet. Exceeding the maximum operating temperature can lead to reduced reliability and lifespan.
• Is the TKH45P20R0FE-TR resistor RoHS and REACH compliant?
  Yes, the TKH45P20R0FE-TR resistor is RoHS (Restriction of Hazardous Substances) and REACH (Registration, Evaluation, Authorization, and Restriction of Chemicals) compliant, making it suitable for use in most modern electronic devices and applications.
• What is the recommended soldering temperature and time for the TKH45P20R0FE-TR?
  Ohmite recommends soldering the TKH45P20R0FE-TR at a temperature of 260°C (500°F) for 3-5 seconds. It's essential to follow the recommended soldering profile to prevent damage to the resistor and ensure reliable operation.
