CDRH4D28CNP-100PC - Sumida

CDRH4D28CNP-100PC Frequently Asked Questions (FAQs)

• What is the recommended PCB land pattern for the CDRH4D28CNP-100PC?
  The recommended PCB land pattern for the CDRH4D28CNP-100PC 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 CDRH4D28CNP-100PC has a maximum operating temperature of 125°C. Ensure good airflow around the inductor, and consider using a heat sink or thermal interface material if the inductor will be operating near its maximum temperature rating.
• What is the inductor's self-resonant frequency (SRF)?
  The SRF of the CDRH4D28CNP-100PC is not explicitly stated in the datasheet, but it can be estimated using the inductor's inductance and capacitance values. A rough estimate can be made using the formula SRF ≈ 1 / (2 * π * sqrt(L * C)), where L is the inductance and C is the capacitance.
• Can I use the CDRH4D28CNP-100PC in a high-vibration environment?
  The CDRH4D28CNP-100PC is designed to withstand moderate vibration, but it's essential to ensure the inductor is properly secured to the PCB and that the PCB is designed to withstand the expected vibration levels. Consult the datasheet and application notes for more information.
• How do I determine the inductor's saturation current?
  The saturation current of the CDRH4D28CNP-100PC can be determined by consulting the inductor's BH curve, which is typically provided in the datasheet or application notes. The BH curve shows the relationship between the inductor's magnetic field strength (H) and magnetic flux density (B).
