B82731M2401A033 Frequently Asked Questions (FAQs)

  • TDK recommends a symmetrical PCB layout with a ground plane underneath the inductor to minimize radiation and ensure optimal performance. A minimum of 1.5 mm clearance from the inductor to the PCB edge is also recommended.
  • The B82731M2401A033 is rated for operation up to 125°C, but its inductance value may decrease by up to 20% at high temperatures. Engineers should consider this when designing for high-temperature applications.
  • The maximum current rating for the B82731M2401A033 is 2.4 A, but this value may vary depending on the operating frequency and temperature. Engineers should consult the datasheet and perform thermal derating calculations to ensure safe operation.
  • Yes, the B82731M2401A033 is suitable for use in switching regulator applications due to its low core loss and high saturation current. However, engineers should ensure that the inductor is properly sized and selected for the specific application requirements.
  • The ESR of the B82731M2401A033 is approximately 0.35 ohms at 100 kHz. This value may vary depending on the operating frequency and temperature.
