B82731M2112A030 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 around the inductor is also recommended.
  • The B82731M2112A030 is rated for operation up to 125°C, but its inductance and resistance may vary with temperature. TDK provides temperature derating curves in the datasheet to help designers estimate the inductor's performance at elevated temperatures.
  • Yes, the B82731M2112A030 is suitable for high-frequency switching applications up to 1 MHz. However, designers should consider the inductor's self-resonant frequency (SRF) and ensure that it is not operated near the SRF to avoid unwanted resonances.
  • TDK recommends a reflow soldering process with a peak temperature of 260°C and a dwell time of 30 seconds. Hand soldering is not recommended due to the inductor's small size and high thermal resistance.
  • Yes, TDK recommends storing the inductors in a dry, cool place away from direct sunlight and moisture. Handling should be done with care to avoid mechanical stress, and electrostatic discharge (ESD) precautions should be taken to prevent damage.
