1226AS-H-2R7M=P2 - Murata Electronics

1226AS-H-2R7M=P2 Frequently Asked Questions (FAQs)

• What is the recommended land pattern for this inductor?
  The recommended land pattern for the 1226AS-H-2R7M=P2 inductor is a rectangular pad with a size of 1.2mm x 1.6mm, with a non-solder mask defined (NSMD) pad shape to ensure proper soldering and thermal relief.
• How do I handle the inductor's thermal derating?
  The 1226AS-H-2R7M=P2 inductor has a temperature derating curve specified in the datasheet. To handle thermal derating, ensure that the inductor is operated within the recommended temperature range (up to 125°C) and consider the derating factor when calculating the maximum current rating.
• What is the inductor's self-resonant frequency (SRF)?
  The self-resonant frequency (SRF) of the 1226AS-H-2R7M=P2 inductor is not explicitly stated in the datasheet, but it can be estimated using the inductor's inductance value and the parasitic capacitance. Typically, the SRF is around 100-200 MHz for this type of inductor.
• Can I use this inductor in a high-frequency application?
  The 1226AS-H-2R7M=P2 inductor is suitable for high-frequency applications up to several hundred MHz, but its performance may degrade above 100 MHz due to the inductor's parasitic capacitance and resistance. Consider using a high-frequency inductor or a different component if your application requires frequencies above 500 MHz.
• How do I ensure the inductor's reliability and lifespan?
  To ensure the reliability and lifespan of the 1226AS-H-2R7M=P2 inductor, follow proper storage and handling procedures, avoid excessive mechanical stress, and operate the inductor within its recommended specifications (voltage, current, and temperature). Regularly inspect the inductor for signs of wear or damage.
