LQH43PB220M26L - Murata Electronics

LQH43PB220M26L Frequently Asked Questions (FAQs)

• What is the recommended land pattern for LQH43PB220M26L?
  The recommended land pattern for LQH43PB220M26L is a rectangular pad with a size of 3.5mm x 2.5mm, with a non-solder mask defined (NSMD) pad shape. The pad should be centered on the component and have a solder mask opening of 2.5mm x 1.5mm.
• How do I handle the component's thermal considerations?
  The LQH43PB220M26L has a maximum operating temperature of 125°C. To ensure reliable operation, it's essential to consider thermal management during PCB design. This includes providing adequate clearance around the component, using thermal vias, and selecting a suitable PCB material with high thermal conductivity.
• What is the self-resonant frequency (SRF) of LQH43PB220M26L?
  The self-resonant frequency (SRF) of LQH43PB220M26L is not explicitly stated in the datasheet. However, based on similar inductors from Murata, the SRF is typically in the range of 100-200 MHz. It's recommended to consult with Murata's application engineers or perform simulations to determine the SRF for specific use cases.
• Can I use LQH43PB220M26L in a high-vibration environment?
  The LQH43PB220M26L is a surface-mount device (SMD) and can be susceptible to vibration-induced failures. While it's designed to meet standard reliability requirements, it's essential to evaluate the component's performance in high-vibration environments. Consider using additional mechanical support or selecting a more robust inductor design for such applications.
• How do I ensure the inductor's magnetic shielding?
  To minimize electromagnetic interference (EMI) and ensure magnetic shielding, it's recommended to use a shielded inductor or add a magnetic shield around the LQH43PB220M26L. This can be achieved using a mu-metal shield or a ferrite plate. Consult with Murata's application engineers or PCB design experts for specific guidance.
