LQH55DN472M03L Frequently Asked Questions (FAQs)

  • The recommended land pattern for the LQH55DN472M03L is a rectangular pad with a size of 3.5mm x 2.5mm, with a non-solder mask defined (NSMD) pad shape.
  • The LQH55DN472M03L has a maximum operating temperature of 125°C. Ensure good airflow around the inductor, and consider using a heat sink or thermal interface material if operating in high-temperature environments.
  • The SRF of the LQH55DN472M03L is approximately 150 MHz. This is the frequency at which the inductor's impedance peaks due to its internal capacitance and inductance.
  • The LQH55DN472M03L has a maximum current rating of 2.5 A. Ensure that your application's current requirements do not exceed this rating to prevent overheating and damage to the inductor.
  • Use a secure mounting method, such as soldering or adhesive, to prevent the inductor from shifting or detaching during vibration. Also, consider using a vibration-resistant coating or potting material to further secure the inductor.
