B82731M2801A030 Frequently Asked Questions (FAQs)

  • TDK recommends a symmetrical PCB layout with a ground plane underneath the inductor to minimize electromagnetic interference (EMI). A minimum of 1.5 mm clearance around the inductor is recommended to prevent parasitic capacitance.
  • The B82731M2801A030 is rated for operation up to 125°C. However, the inductance value may decrease by up to 10% at high temperatures. It's essential to consider derating factors and thermal management in high-temperature applications.
  • The maximum allowable DC current for the B82731M2801A030 is 2.8 A. Exceeding this current may cause the inductor to overheat, leading to reduced lifespan or even failure.
  • Yes, the B82731M2801A030 is suitable for switching regulator applications. However, it's essential to consider the inductor's core losses, which may affect the overall efficiency of the regulator. TDK recommends using their Power Inductor Loss Calculator to estimate core losses.
  • The ESR of the B82731M2801A030 is approximately 120 mΩ at 100 kHz. This value may vary depending on the operating frequency and temperature.
