LM-NP-1004L Frequently Asked Questions (FAQs)

  • Bourns recommends a symmetrical PCB layout with the inductor centered on the board, and keeping the traces as short and wide as possible to minimize parasitic inductance and resistance.
  • The LM-NP-1004L has a maximum operating temperature of 125°C. Ensure good airflow around the inductor, and consider using a thermal pad or heat sink if the application requires high current or high ambient temperatures.
  • The SRF of the LM-NP-1004L is not explicitly stated in the datasheet, but it can be estimated using the inductor's inductance and capacitance values. Typically, it falls in the range of 10-50 MHz.
  • Yes, the LM-NP-1004L is designed to withstand vibrations up to 10g (sinusoidal vibration, 10-2000 Hz). However, it's essential to ensure the inductor is properly secured to the PCB and the PCB is rigid enough to prevent mechanical stress.
  • The LM-NP-1004L has an MSL rating of 1, which means it can withstand normal humidity levels without special handling or storage precautions.
