LQB15NNR47K10D Frequently Asked Questions (FAQs)

• What is the recommended land pattern for LQB15NNR47K10D?
  The recommended land pattern for LQB15NNR47K10D is a rectangular pad with a size of 1.5 mm x 1.5 mm, with a non-solder mask defined (NSMD) pad shape. The pad should be centered on the component and have a solder mask clearance of 0.15 mm.
• How do I handle the LQB15NNR47K10D inductor during reflow soldering?
  During reflow soldering, the LQB15NNR47K10D inductor should be placed on the PCB with the component marking side up. The recommended reflow profile is a peak temperature of 260°C, with a dwell time of 20-30 seconds above 220°C.
• Is the LQB15NNR47K10D inductor suitable for high-frequency applications?
  Yes, the LQB15NNR47K10D inductor is suitable for high-frequency applications up to 1 GHz due to its low core loss and high self-resonant frequency (SRF). However, the inductor's performance may degrade at frequencies above 500 MHz, and additional simulation and testing may be required.
• Can I use the LQB15NNR47K10D inductor in a high-temperature environment?
  The LQB15NNR47K10D inductor is rated for operation up to 125°C, but its performance may degrade at higher temperatures. If your application requires operation above 125°C, you should consult with Murata's application engineers or consider using a different inductor model.
• How do I ensure the LQB15NNR47K10D inductor is properly secured to the PCB?
  The LQB15NNR47K10D inductor should be secured to the PCB using a suitable adhesive, such as a cyanoacrylate-based adhesive, to prevent movement during handling and operation. Additionally, the inductor's leads should be soldered to the PCB to ensure a reliable electrical connection.
