LQM18PN2R2MFRL - Murata Electronics

LQM18PN2R2MFRL Frequently Asked Questions (FAQs)

• What is the recommended land pattern for this inductor?
  The recommended land pattern for the LQM18PN2R2MFRL is a rectangular pad with a size of 1.8mm x 1.3mm, with a non-solder mask defined (NSMD) pad shape.
• How do I handle the inductor's thermal considerations?
  The LQM18PN2R2MFRL 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.
• What is the inductor's self-resonant frequency (SRF)?
  The SRF of the LQM18PN2R2MFRL is not explicitly stated in the datasheet, but it can be estimated to be around 100-150 MHz based on the inductor's physical characteristics and Murata's general guidelines.
• Can I use this inductor in a high-frequency application?
  While the LQM18PN2R2MFRL is suitable for high-frequency applications, its performance may degrade above 100 MHz due to skin effect and proximity effect losses. Consider using a high-frequency optimized inductor or consulting with Murata's application engineers for specific guidance.
• How do I ensure the inductor's reliability in a high-vibration environment?
  To ensure reliability in high-vibration environments, ensure the inductor is properly secured to the PCB using a suitable adhesive or mechanical fastening method, and consider using a vibration-resistant coating or potting compound.
