151031SS04000 datasheet by Wurth Elektronik

151031SS04000 Frequently Asked Questions (FAQs)

• What is the recommended land pattern for this inductor?
  The recommended land pattern for the 151031SS04000 inductor is a rectangular pad with a size of 3.5 mm x 2.5 mm, with a non-solder mask defined (NSMD) pad shape.
• How do I handle the inductor's thermal considerations?
  The 151031SS04000 inductor has a maximum operating temperature of 125°C. Ensure proper thermal management by providing adequate airflow, using a heat sink if necessary, and avoiding high-power density designs.
• What is the inductor's self-resonant frequency (SRF)?
  The self-resonant frequency (SRF) of the 151031SS04000 inductor is not explicitly stated in the datasheet. However, as a general guideline, the SRF for similar inductors in this series is typically in the range of 100-200 MHz.
• Can I use this inductor in a high-reliability or aerospace application?
  While the 151031SS04000 inductor is a high-quality component, it may not meet the specific requirements for high-reliability or aerospace applications. Consult with Wurth Elektronik or a qualified engineer to determine the inductor's suitability for such applications.
• How do I ensure the inductor's magnetic shielding?
  To ensure proper magnetic shielding, keep the inductor at least 2-3 mm away from other components and avoid placing it near ferromagnetic materials. Additionally, consider using a shielded inductor or a mu-metal shield to minimize electromagnetic interference (EMI).
