CDRH5D28RHPNP-4R7NC - Sumida

CDRH5D28RHPNP-4R7NC Frequently Asked Questions (FAQs)

• What is the recommended land pattern for this inductor?
  The recommended land pattern for the CDRH5D28RHPNP-4R7NC is a rectangular pad with a size of 3.5mm x 2.5mm, with a non-solder mask defined (NSMD) pad shape.
• How do I handle the inductor's thermal considerations?
  The CDRH5D28RHPNP-4R7NC 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 high currents or high ambient temperatures are expected.
• What is the inductor's self-resonant frequency (SRF)?
  The SRF of the CDRH5D28RHPNP-4R7NC is approximately 150 MHz. This is the frequency at which the inductor's impedance peaks due to its internal capacitance and inductance.
• Can I use this inductor in a high-reliability or safety-critical application?
  The CDRH5D28RHPNP-4R7NC is a commercial-grade inductor, but it is not specifically designed for high-reliability or safety-critical applications. If you need an inductor for such an application, consider using a component with a higher reliability rating, such as an inductor with a higher temperature rating or a specialized automotive or aerospace-grade inductor.
• How do I ensure the inductor's magnetic field does not interfere with nearby components?
  To minimize magnetic field interference, keep the inductor at least 5mm away from nearby components, and consider using a shielded inductor or a mu-metal shield around the inductor. You can also use simulation tools to model the inductor's magnetic field and optimize the component placement.
