CSS2H-3920R-L200FE - Bourns

CSS2H-3920R-L200FE Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance?
  A symmetrical layout with a solid ground plane and minimal signal trace length is recommended. Keep the input and output traces separate and avoid crossing them to minimize noise and crosstalk.
• How do I ensure the inductor's self-resonant frequency (SRF) doesn't affect my design?
  Choose an operating frequency below the SRF (approximately 150 MHz for the CSS2H-3920R-L200FE). Use a series resistor or a ferrite bead to dampen resonant peaks if necessary.
• What is the maximum allowed voltage across the inductor?
  The maximum allowed voltage is 200 Vrms. Exceeding this voltage may cause the inductor to saturate or fail.
• How do I handle the inductor's temperature rise during operation?
  Ensure good airflow around the inductor and consider using a heat sink if the ambient temperature exceeds 40°C. The inductor's temperature rise is approximately 20°C/W.
• Can I use the CSS2H-3920R-L200FE in a high-reliability or safety-critical application?
  While the CSS2H-3920R-L200FE is a high-quality component, it is not specifically designed for high-reliability or safety-critical applications. Consider using a component with a higher reliability rating, such as those with a higher mean time between failures (MTBF) or those that meet specific industry standards (e.g., AEC-Q200).
