LQH5BPN151M38L - Murata Electronics

LQH5BPN151M38L Frequently Asked Questions (FAQs)

• What is the recommended land pattern for LQH5BPN151M38L?
  The recommended land pattern for LQH5BPN151M38L is a rectangular pad with a size of 2.5mm x 1.5mm, with a non-solder mask defined (NSMD) pad shape. The pad should be centered on the component and have a clearance of at least 0.2mm from the component body.
• How do I handle the LQH5BPN151M38L inductor during reflow soldering?
  During reflow soldering, the LQH5BPN151M38L inductor should be placed on the PCB with the component body facing upwards. The recommended reflow profile is a peak temperature of 260°C, with a dwell time of 20-30 seconds above 220°C. Ensure that the component is properly secured to the PCB to prevent movement during the reflow process.
• What is the maximum current rating for the LQH5BPN151M38L inductor?
  The maximum current rating for the LQH5BPN151M38L inductor is 1.5A. However, the actual current handling capability may vary depending on the operating frequency, temperature, and other environmental factors. It's recommended to derate the current rating by 20-30% to ensure reliable operation.
• Can I use the LQH5BPN151M38L inductor in a high-temperature environment?
  The LQH5BPN151M38L inductor is rated for operation up to 125°C. However, the inductor's performance and reliability may degrade at higher temperatures. If your application requires operation above 125°C, it's recommended to consult with Murata's application engineers or consider using a different inductor model designed for high-temperature applications.
• How do I ensure the LQH5BPN151M38L inductor is properly secured to the PCB?
  To ensure the LQH5BPN151M38L inductor is properly secured to the PCB, apply a small amount of adhesive, such as a dot of epoxy or acrylic adhesive, to the component body before placing it on the PCB. This will help prevent the inductor from shifting during reflow soldering or other manufacturing processes.
