104CDMCCDS-4R7MC - Sumida

104CDMCCDS-4R7MC Frequently Asked Questions (FAQs)

• What is the recommended PCB footprint for the 104CDMCCDS-4R7MC?
  The recommended PCB footprint for the 104CDMCCDS-4R7MC is a rectangular pad with dimensions of 1.5mm x 1.2mm, with a 0.5mm hole in the center for the inductor's lead.
• How do I handle the inductor's thermal considerations?
  The 104CDMCCDS-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 the inductor will be operating near its maximum temperature rating.
• What is the inductor's self-resonant frequency?
  The self-resonant frequency of the 104CDMCCDS-4R7MC is approximately 100 MHz. This is the frequency at which the inductor's inductive reactance equals its capacitive reactance.
• Can I use the 104CDMCCDS-4R7MC in a high-vibration environment?
  Yes, the 104CDMCCDS-4R7MC is designed to withstand vibrations up to 10G. However, it's recommended to secure the inductor to the PCB using a suitable adhesive or mechanical fastening method to prevent movement or damage.
• How do I ensure the inductor's reliability in a high-humidity environment?
  To ensure reliability in high-humidity environments, apply a conformal coating to the inductor and surrounding PCB area. This will help protect the inductor from moisture and corrosion.
