1227AS-H-120M=P2 - Murata Electronics

1227AS-H-120M=P2 Frequently Asked Questions (FAQs)

• What is the recommended land pattern for this inductor?
  The recommended land pattern for the 1227AS-H-120M=P2 can be found in the Murata Land Pattern Recommendation document, which provides guidelines for optimal PCB layout and pad design.
• How do I handle the inductor's thermal derating?
  The thermal derating of the 1227AS-H-120M=P2 is typically handled by reducing the maximum current rating as the operating temperature increases. A derating curve can be found in the datasheet or by consulting with Murata's application engineers.
• What is the inductor's self-resonant frequency (SRF)?
  The self-resonant frequency (SRF) of the 1227AS-H-120M=P2 is typically not specified in the datasheet, but it can be estimated using the inductor's inductance and capacitance values. For a more accurate value, consult with Murata's application engineers or perform your own measurements.
• Can I use this inductor in a high-frequency application?
  The 1227AS-H-120M=P2 is designed for general-purpose use and may not be suitable for high-frequency applications. For high-frequency applications, consider using Murata's high-frequency inductor series, such as the LQW series, which are designed for high-frequency performance.
• How do I ensure the inductor's reliability in a high-reliability application?
  To ensure the reliability of the 1227AS-H-120M=P2 in a high-reliability application, follow proper storage and handling procedures, use a robust PCB design, and consider using Murata's high-reliability inductor series, such as the RH series, which are designed for high-reliability applications.
