LQH2MPN1R5NGRL - Murata Electronics

LQH2MPN1R5NGRL Frequently Asked Questions (FAQs)

• What is the recommended land pattern for this inductor?
  The recommended land pattern for the LQH2MPN1R5NGRL is a rectangular pad with a size of 2.5mm x 1.6mm, with a non-solder mask defined (NSMD) pad shape. This ensures proper soldering and minimizes the risk of solder bridging.
• How do I handle the inductor's thermal considerations?
  The LQH2MPN1R5NGRL has a maximum operating temperature of 125°C. To ensure reliable operation, keep the inductor away from heat sources, use a sufficient thermal pad, and consider the PCB's thermal conductivity and airflow when designing the layout.
• What is the inductor's self-resonant frequency (SRF)?
  The SRF of the LQH2MPN1R5NGRL is approximately 150 MHz. This is important to consider when designing filters or impedance matching circuits to avoid unwanted resonances.
• Can I use this inductor in a high-frequency application?
  While the LQH2MPN1R5NGRL is suitable for high-frequency applications, its performance may degrade above 100 MHz due to skin effect and proximity effect losses. For frequencies above 100 MHz, consider using a high-frequency optimized inductor or a different component.
• How do I ensure the inductor's reliability in a humid environment?
  To ensure reliability in humid environments, follow proper storage and handling procedures, and consider applying a conformal coating to the PCB. Murata also recommends using a moisture-resistant coating or encapsulation for the inductor.
