291-1K-RC Frequently Asked Questions (FAQs)

  • The recommended soldering temperature for the 291-1K-RC is between 260°C to 280°C for a maximum of 10 seconds.
  • While the 291-1K-RC is a general-purpose resistor, it's not ideal for high-frequency applications above 100 kHz due to its inductive properties. For high-frequency applications, consider using a thin-film or metal-film resistor instead.
  • The 291-1K-RC has a maximum operating temperature of 155°C. While it can tolerate short-term excursions up to 200°C, prolonged exposure above 155°C may affect its reliability and lifespan.
  • Yes, the 291-1K-RC is compatible with lead-free soldering processes, making it suitable for RoHS-compliant designs.
  • The power rating of the 291-1K-RC decreases as the operating temperature increases. At 70°C, the power rating is 0.25W, and at 155°C, it's 0.1W. Consult the datasheet for a detailed derating curve.
