RLB0914-470KL - Bourns

RLB0914-470KL Frequently Asked Questions (FAQs)

• What is the recommended PCB land pattern for the RLB0914-470KL?
  The recommended PCB land pattern for the RLB0914-470KL can be found in the Bourns Application Note S-8151, which provides a detailed layout and footprint recommendation for optimal performance.
• How do I handle the inductor's thermal considerations?
  The RLB0914-470KL has a maximum operating temperature of 125°C. Ensure good airflow around the inductor, and consider using a thermal pad or heat sink if the application requires high current or high ambient temperatures.
• What is the inductor's self-resonant frequency (SRF)?
  The SRF of the RLB0914-470KL is not explicitly stated in the datasheet, but it can be estimated using the inductor's inductance and capacitance values. A rough estimate can be calculated using the formula SRF ≈ 1 / (2 * π * sqrt(L * C)), where L is the inductance and C is the capacitance.
• Can I use the RLB0914-470KL in a high-vibration environment?
  The RLB0914-470KL is a surface-mount device and can be susceptible to vibration-induced failure. However, Bourns Inc. provides a vibration test report (S-8153) that demonstrates the inductor's robustness in vibration environments. Consult the report for specific details and recommendations.
• How do I ensure the inductor's reliability in high-reliability applications?
  Bourns Inc. provides a reliability report (S-8152) that outlines the inductor's reliability testing and results. Follow the recommended storage and handling procedures, and consider using a conformal coating to protect the inductor from environmental factors.
