LQH43NH100J03L - Murata Electronics

LQH43NH100J03L Frequently Asked Questions (FAQs)

• What is the recommended land pattern for LQH43NH100J03L?
  The recommended land pattern for LQH43NH100J03L 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 LQH43NH100J03L's sensitivity to soldering temperature?
  To minimize the risk of damage, it's recommended to follow the recommended soldering temperature profile: 260°C (max) for 10 seconds (max) using a soldering iron, or 240°C (max) for 30 seconds (max) using a reflow oven. Avoid using excessive soldering temperature or time, as this can cause damage to the inductor.
• What is the maximum allowable DC current for LQH43NH100J03L?
  The maximum allowable DC current for LQH43NH100J03L is 1.8A. Exceeding this current may cause the inductor to overheat, leading to reduced performance or even failure.
• How do I ensure the LQH43NH100J03L is properly secured to the PCB?
  To ensure the LQH43NH100J03L is properly secured to the PCB, use a suitable adhesive, such as a silicone-based adhesive, and apply a moderate amount of pressure to the component during the assembly process. Additionally, ensure the PCB is designed with a sufficient keep-out area around the inductor to prevent mechanical stress.
• What is the equivalent series resistance (ESR) of the LQH43NH100J03L?
  The equivalent series resistance (ESR) of the LQH43NH100J03L is approximately 0.45 ohms at 100 kHz. This value may vary depending on the operating frequency and temperature.
