S3483R-220M - API Delevan

S3483R-220M Frequently Asked Questions (FAQs)

• What is the recommended PCB land pattern for the S3483R-220M?
  The recommended PCB land pattern for the S3483R-220M can be found in the API Delevan application note AN-113, which provides detailed guidelines for PCB layout and design.
• How does the S3483R-220M perform in high-temperature environments?
  The S3483R-220M is rated for operation up to 155°C, but derating is required above 125°C. Consult the API Delevan temperature derating chart for specific guidance on inductor performance at elevated temperatures.
• Is the S3483R-220M compatible with lead-free soldering processes?
  Yes, the S3483R-220M is compatible with lead-free soldering processes, including RoHS and WEEE compliance. However, it's essential to follow the recommended soldering profile to ensure reliable assembly.
• What is the self-resonant frequency (SRF) of the S3483R-220M?
  The self-resonant frequency (SRF) of the S3483R-220M is not explicitly stated in the datasheet, but it can be estimated using the inductor's inductance and capacitance values. Typically, the SRF is around 100-200 MHz for this inductor.
• Can the S3483R-220M be used in high-current applications?
  While the S3483R-220M is rated for 22.5 A, it's essential to consider the inductor's thermal performance and derating factors when designing for high-current applications. Consult the API Delevan application note AN-114 for guidance on high-current inductor selection.
