SRR1005-561K - Bourns

SRR1005-561K Frequently Asked Questions (FAQs)

• What is the recommended PCB land pattern for the SRR1005-561K?
  Bourns provides a recommended PCB land pattern in their application note AN204, which can be found on their website. The land pattern is designed to ensure proper soldering and thermal management.
• How do I handle the SRR1005-561K during assembly to prevent damage?
  Bourns recommends handling the SRR1005-561K by the edges or the terminals, avoiding touching the ceramic body or the resistive element. This prevents damage from electrostatic discharge (ESD) and mechanical stress.
• What is the maximum allowable voltage imbalance across the SRR1005-561K?
  Although not explicitly stated in the datasheet, Bourns recommends limiting the voltage imbalance to 10% of the rated voltage to ensure reliable operation and prevent damage.
• Can I use the SRR1005-561K in a high-frequency application?
  While the SRR1005-561K is designed for general-purpose use, it may not be suitable for high-frequency applications (>1 MHz) due to its internal construction and parasitic elements. Bourns recommends using their high-frequency-specific resistors, such as the SRN series, for such applications.
• How do I determine the power rating of the SRR1005-561K in a specific application?
  The power rating of the SRR1005-561K depends on the ambient temperature, airflow, and PCB design. Bourns provides a power derating curve in the datasheet, which can be used to determine the maximum allowable power dissipation in a specific application.
