CDEIR6D31FHF-4R7MC - Sumida

CDEIR6D31FHF-4R7MC Frequently Asked Questions (FAQs)

• What is the recommended PCB land pattern for the CDEIR6D31FHF-4R7MC?
  The recommended PCB land pattern is a rectangular pad with a size of 3.5mm x 2.5mm, with a 1.5mm diameter hole in the center for the inductor's lead.
• How do I handle the inductor's thermal considerations?
  The CDEIR6D31FHF-4R7MC has a maximum operating temperature of 125°C. Ensure good airflow around the inductor, and consider using a heat sink or thermal pad if operating in high-temperature environments.
• What is the inductor's self-resonant frequency (SRF)?
  The SRF of the CDEIR6D31FHF-4R7MC is approximately 150 MHz. This is important to consider when designing filters or impedance matching networks.
• Can I use the CDEIR6D31FHF-4R7MC in a high-reliability or aerospace application?
  While the CDEIR6D31FHF-4R7MC is a high-quality inductor, it is not specifically designed for high-reliability or aerospace applications. Consider using a more specialized inductor or consulting with Sumida Corporation for custom solutions.
• How do I ensure the inductor is properly soldered to the PCB?
  Use a soldering iron with a temperature of 250°C to 270°C, and apply a small amount of solder paste to the PCB pads. Ensure the inductor is properly aligned and seated before soldering.
