CD30D22HF-680MC - Sumida

CD30D22HF-680MC Frequently Asked Questions (FAQs)

• What is the recommended PCB layout and land pattern for optimal performance?
  The recommended PCB layout and land pattern can be found in the Sumida Corporation's application note AN-1301, which provides guidelines for optimal performance and reduced electromagnetic interference (EMI).
• How does the inductor perform in high-temperature environments?
  The CD30D22HF-680MC is rated for operation up to 125°C, but it's recommended to derate the current rating by 1.5% per degree Celsius above 80°C to ensure reliable operation. Consult with Sumida Corporation's application engineers for specific guidance on high-temperature applications.
• What is the self-resonant frequency (SRF) of the inductor?
  The SRF of the CD30D22HF-680MC is not explicitly stated in the datasheet, but it can be estimated using the inductor's inductance value and the PCB layout. As a general guideline, the SRF is typically above 100 MHz for this type of inductor. Consult with Sumida Corporation's application engineers for specific guidance on SRF and impedance characteristics.
• Is the inductor compatible with high-frequency switching converters?
  Yes, the CD30D22HF-680MC is designed for high-frequency switching converters and can operate up to 2 MHz. However, it's essential to consider the inductor's core losses, winding losses, and impedance characteristics when designing the converter to ensure optimal performance and efficiency.
• What is the recommended soldering profile for this inductor?
  The recommended soldering profile for the CD30D22HF-680MC is a peak temperature of 260°C for 10 seconds, with a ramp-up rate of 3°C/s and a ramp-down rate of 6°C/s. Consult with Sumida Corporation's application engineers for specific guidance on soldering and assembly.
