LQH43NN121J03L Frequently Asked Questions (FAQ)

  • The recommended land pattern for LQH43NN121J03L is a rectangular pad with a size of 3.2mm 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 2.2mm x 1.5mm.

  • During reflow soldering, the LQH43NN121J03L inductor should be placed on the PCB with the component marking side facing up. The recommended reflow profile is a peak temperature of 260°C, with a dwell time of 20-30 seconds above 220°C.

  • Yes, the LQH43NN121J03L inductor is suitable for high-frequency applications up to 1 GHz. However, it's essential to consider the inductor's self-resonant frequency (SRF) and ensure that it does not resonate at the operating frequency.

  • To calculate the effective inductance, consider the inductor's nominal inductance value, the operating frequency, and the circuit's impedance. You can use simulation tools or consult with a Murata application engineer for guidance.

  • The maximum current rating for the LQH43NN121J03L inductor is 1.2A. However, the actual current handling capability may vary depending on the operating frequency, temperature, and circuit conditions.
