LQH43MN390J03L Frequently Asked Questions (FAQs)

  • The recommended land pattern for LQH43MN390J03L is a rectangular pad with a size of 3.3mm 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.
  • To minimize the risk of damage, it's recommended to follow the recommended soldering temperature profile: 260°C (max) for 10 seconds (max) when using a reflow oven, and 230°C (max) for 5 seconds (max) when using a wave soldering machine.
  • The maximum allowable DC current for LQH43MN390J03L is 3.9A. Exceeding this current may cause the inductor to overheat, leading to reduced performance or even failure.
  • While the LQH43MN390J03L is designed for general-purpose use, it's not recommended for high-frequency applications (>100MHz) due to its relatively high equivalent series resistance (ESR) and inductance tolerance. For high-frequency applications, consider using a specialized high-frequency inductor.
  • To ensure the LQH43MN390J03L is properly secured to the PCB, use a suitable adhesive, such as a silicone-based adhesive, and follow the recommended mounting procedure. Additionally, consider using a mechanical clamp or a bracket to prevent the inductor from shifting during assembly or operation.
