LQM18DN330M70L - Murata Electronics

LQM18DN330M70L Frequently Asked Questions (FAQs)

• What is the recommended land pattern for this inductor?
  The recommended land pattern for the LQM18DN330M70L can be found in the Murata Land Pattern Recommendation document, which provides detailed information on the recommended pad layout and dimensions for optimal performance and reliability.
• How do I handle the inductor's thermal considerations?
  The LQM18DN330M70L has a maximum operating temperature of 125°C. To ensure reliable operation, it's essential to consider thermal management in the design, such as providing adequate airflow, using thermal vias, and selecting a suitable PCB material with high thermal conductivity.
• What is the inductor's self-resonant frequency (SRF)?
  The self-resonant frequency (SRF) of the LQM18DN330M70L is not explicitly stated in the datasheet. However, Murata provides an SRF calculator tool on their website, which can be used to estimate the SRF based on the inductor's characteristics and operating conditions.
• Can I use this inductor in a high-vibration environment?
  The LQM18DN330M70L is designed to meet the vibration requirements of IEC 60068-2-6, which specifies a vibration amplitude of 10 mm and a frequency range of 10-2000 Hz. However, it's essential to evaluate the inductor's performance in the specific vibration environment and consider additional mechanical stress testing if necessary.
• How do I ensure the inductor's reliability in high-temperature storage?
  To ensure the reliability of the LQM18DN330M70L in high-temperature storage, it's essential to follow Murata's storage guidelines, which recommend storing the components in a dry, cool place, away from direct sunlight, and within the specified storage temperature range of -40°C to 125°C.
