CAT16-222J2LF - Bourns

CAT16-222J2LF Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance?
  Bourns recommends a symmetrical PCB layout with a solid ground plane, and keeping the input and output traces as short as possible to minimize parasitic inductance and capacitance.
• How do I ensure the inductor's self-resonant frequency (SRF) doesn't affect my design?
  To minimize the impact of SRF, ensure the operating frequency is below the SRF, and use a suitable PCB layout and shielding to reduce parasitic effects. You can also consider using a different inductor with a higher SRF if necessary.
• What is the maximum allowed voltage across the inductor?
  The maximum allowed voltage across the inductor is determined by the insulation resistance and the dielectric strength of the materials used. For the CAT16-222J2LF, the maximum voltage rating is 250 Vrms, but it's recommended to derate the voltage to ensure reliable operation.
• How does the inductor's temperature rise affect its performance?
  The inductor's temperature rise can cause a decrease in inductance, an increase in DC resistance, and a reduction in saturation current. Ensure proper thermal management and derating to prevent excessive temperature rise and maintain reliable operation.
• Can I use this inductor in a high-reliability or safety-critical application?
  The CAT16-222J2LF is a commercial-grade inductor, and its use in high-reliability or safety-critical applications may require additional testing and validation. It's recommended to consult with Bourns or a qualified reliability engineer to determine the inductor's suitability for such applications.
