LQH2MCN120K02L - Murata Electronics

LQH2MCN120K02L Frequently Asked Questions (FAQs)

• What is the recommended land pattern for LQH2MCN120K02L?
  The recommended land pattern for LQH2MCN120K02L 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.
• Can I use the LQH2MCN120K02L in a high-temperature environment?
  The LQH2MCN120K02L is rated for operation up to 125°C, but it's recommended to derate the current rating according to the temperature derating curve provided in the datasheet. Above 125°C, the inductor's performance and reliability may be compromised.
• How do I handle the LQH2MCN120K02L's magnetic field in a densely populated PCB?
  To minimize the impact of the magnetic field, keep the inductor at least 5mm away from other components, especially those sensitive to magnetic fields. You can also use shielding techniques, such as placing a grounded copper plane or a magnetic shield between the inductor and other components.
• What is the self-resonant frequency (SRF) of the LQH2MCN120K02L?
  The SRF of the LQH2MCN120K02L is not explicitly stated in the datasheet, but it can be estimated using the inductor's inductance value and the parasitic capacitance. Typically, the SRF is around 100-200 MHz for this type of inductor.
• Can I use the LQH2MCN120K02L in a high-frequency application (e.g., above 100 MHz)?
  While the LQH2MCN120K02L is not specifically designed for high-frequency applications, it can be used up to 100 MHz with careful consideration of the inductor's impedance, parasitic capacitance, and self-resonant frequency. However, for frequencies above 100 MHz, a more suitable inductor with a higher SRF and lower parasitic capacitance may be required.
