DLW43SH101XK2L - Murata Electronics

DLW43SH101XK2L Frequently Asked Questions (FAQs)

• What is the recommended PCB land pattern for the DLW43SH101XK2L?
  The recommended PCB land pattern for the DLW43SH101XK2L is a rectangular pad with a size of 3.5mm x 2.5mm, with a 1.5mm diameter hole in the center for the inductor's lead.
• How do I handle the inductor's thermal considerations?
  The DLW43SH101XK2L has a maximum operating temperature of 125°C. Ensure good airflow around the inductor, and consider using a heat sink or thermal pad if the ambient temperature exceeds 85°C.
• What is the inductor's self-resonant frequency (SRF)?
  The SRF of the DLW43SH101XK2L is not explicitly stated in the datasheet. However, based on similar inductors, the SRF is typically in the range of 100-200 MHz. For precise values, consult with Murata's application engineers or perform your own measurements.
• Can I use the DLW43SH101XK2L in a high-vibration environment?
  The DLW43SH101XK2L is designed to withstand moderate vibrations. However, for high-vibration environments, consider using a more robust inductor or adding mechanical reinforcement to the PCB.
• How do I ensure the inductor's reliability in high-humidity environments?
  To ensure reliability in high-humidity environments, apply a conformal coating to the PCB, and consider using a moisture-resistant inductor or a hermetically sealed package.
