LQM21FN470N00L Frequently Asked Questions (FAQs)

  • The recommended land pattern for the LQM21FN470N00L can be found in the Murata Land Pattern document, which provides detailed information on the recommended pad layout and dimensions for optimal assembly and reliability.
  • The LQM21FN470N00L is rated for operation up to 125°C. For high-temperature applications, ensure that the inductor is derated according to the temperature derating curve provided in the datasheet. Additionally, consider using a thermal interface material to improve heat dissipation.
  • The self-resonant frequency of the LQM21FN470N00L is not explicitly stated in the datasheet. However, it can be estimated using the inductor's inductance and capacitance values. For a more accurate calculation, consult with a Murata application engineer or use a simulation tool like LTspice.
  • The LQM21FN470N00L is rated for a maximum current of 2.5A. For high-current applications, consider using a larger inductor or paralleling multiple LQM21FN470N00L inductors. Ensure that the inductor's thermal rating is not exceeded, and that the PCB layout is designed to handle the increased current.
  • Consult with a Murata application engineer or use a simulation tool like LTspice to model the LQM21FN470N00L in your specific application. This will help ensure that the inductor meets your requirements for inductance, current handling, and frequency response.
