CDRH104RNP-680NC - Sumida

CDRH104RNP-680NC Frequently Asked Questions (FAQs)

• What is the recommended PCB footprint for the CDRH104RNP-680NC?
  The recommended PCB footprint for the CDRH104RNP-680NC is a rectangular pad with dimensions of 4.5mm x 3.5mm, with a 1.5mm diameter hole in the center for the inductor's lead.
• How do I handle the inductor's thermal considerations?
  The CDRH104RNP-680NC has a maximum operating temperature of 125°C. Ensure good airflow around the inductor, and consider using a thermal pad or heat sink if the application requires high current or high ambient temperatures.
• What is the inductor's self-resonant frequency (SRF)?
  The SRF of the CDRH104RNP-680NC is typically around 100 MHz, but this can vary depending on the specific application and PCB layout. It's essential to consider the SRF when designing the circuit to avoid unwanted resonances.
• Can I use the CDRH104RNP-680NC in a high-reliability or safety-critical application?
  The CDRH104RNP-680NC is a commercial-grade inductor, but it's not specifically designed for high-reliability or safety-critical applications. If your application requires high reliability or safety, consider using a more specialized inductor or consulting with Sumida Corporation for a custom solution.
• How do I ensure the inductor's magnetic field doesn't interfere with nearby components?
  To minimize magnetic field interference, keep the CDRH104RNP-680NC at least 5mm away from sensitive components, and consider using shielding or a mu-metal shield to contain the magnetic field.
