B82721A2401N020 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 recommended to prevent electromagnetic interference.
  • The B82721A2401N020 is rated for operation up to 125°C, but its inductance value may decrease by up to 20% at high temperatures. Engineers should consider derating the inductor's performance and ensuring adequate thermal management in their design.
  • TDK recommends a reflow soldering process with a peak temperature of 260°C for 10-30 seconds. Engineers should ensure that the soldering process does not exceed these parameters to prevent damage to the inductor.
  • The B82721A2401N020 is designed to withstand vibrations up to 10 G (10-2000 Hz). However, engineers should consider additional mechanical fixation or potting to ensure the inductor remains securely in place in high-vibration applications.
  • When used in parallel or series configurations, the inductor's behavior can be complex and dependent on the specific application. Engineers should consult TDK's application notes and perform thorough simulations to ensure the desired performance is achieved.
