1239AS-H-2R2M=P2 - Murata Electronics

1239AS-H-2R2M=P2 Frequently Asked Questions (FAQs)

• What is the recommended land pattern for this inductor?
  The recommended land pattern for the 1239AS-H-2R2M=P2 inductor is a rectangular pad with a size of 1.2mm x 0.8mm, with a non-solder mask defined (NSMD) pad shape.
• How do I handle the inductor's thermal considerations?
  The 1239AS-H-2R2M=P2 inductor has a maximum operating temperature of 125°C. Ensure proper thermal design and heat dissipation in your application to prevent overheating. A thermal pad or heat sink may be necessary.
• What is the inductor's self-resonant frequency (SRF)?
  The self-resonant frequency (SRF) of the 1239AS-H-2R2M=P2 inductor is approximately 150 MHz. This is the frequency at which the inductor's impedance peaks due to its internal capacitance and inductance.
• Can I use this inductor in a high-frequency application?
  While the 1239AS-H-2R2M=P2 inductor is suitable for high-frequency applications, its performance may degrade above 100 MHz. For frequencies above 100 MHz, consider using a high-frequency inductor specifically designed for such applications.
• How do I ensure the inductor's reliability in a high-reliability application?
  To ensure the reliability of the 1239AS-H-2R2M=P2 inductor in a high-reliability application, follow proper storage, handling, and soldering procedures. Also, consider using a conformal coating to protect the inductor from environmental factors.
