LPS4018-684MRC Frequently Asked Questions (FAQ)

  • Coilcraft provides a recommended land pattern for the LPS4018-684MRC in their datasheet, which includes dimensions for the pad size, spacing, and solder mask clearance. It's essential to follow this pattern to ensure proper assembly and to prevent soldering issues.

  • The LPS4018-684MRC has a maximum operating temperature of 125°C. To ensure reliable operation, it's crucial to consider thermal management in your design. This includes providing adequate airflow, using thermal vias, and keeping the inductor away from heat sources. Coilcraft also provides thermal resistance data in their datasheet to help with thermal calculations.

  • The self-resonant frequency (SRF) of the LPS4018-684MRC is not explicitly stated in the datasheet. However, Coilcraft provides an impedance vs. frequency graph that can be used to estimate the SRF. Typically, the SRF is the frequency at which the impedance peaks. In this case, the SRF is approximately 150 MHz.

  • The LPS4018-684MRC is a surface-mount device, and its mechanical robustness is suitable for most applications. However, if your design will be subjected to extreme vibration or mechanical stress, you should consider additional mechanical support or potting to ensure the inductor's reliability. Coilcraft also offers other inductor series with enhanced mechanical robustness, such as the MSS series.

  • The saturation current of the LPS4018-684MRC is not explicitly stated in the datasheet. However, Coilcraft provides a graph of inductance vs. current in their datasheet. By examining this graph, you can determine the point at which the inductance begins to drop significantly, indicating the onset of saturation. Typically, this occurs around 10-15% below the maximum rated current.
