39SB-1RB-503 Frequently Asked Questions (FAQs)

  • Bourns provides a recommended PCB layout and land pattern in their application note AN164, which can be found on their website. It's essential to follow these guidelines to ensure proper mounting and to minimize thermal resistance.
  • To select the correct resistor value, consider the maximum current and voltage ratings of the 39SB-1RB-503, as well as the desired power rating. You can use Bourns' online resistor calculator or consult with their application engineers for guidance.
  • The 39SB-1RB-503 has an operating temperature range of -55°C to +150°C. However, the power rating is derated above 125°C, and the device should not be operated above 150°C for extended periods.
  • The 39SB-1RB-503 is designed for general-purpose applications and is not optimized for high-frequency use. For high-frequency applications, consider using Bourns' high-frequency resistor series, such as the CHV series.
  • The 39SB-1RB-503 has an MSL rating of 1, which means it can withstand normal humidity levels and does not require special handling or storage.
