1255AY-2R2N=P3 - Murata Electronics

1255AY-2R2N=P3 Frequently Asked Questions (FAQs)

• What is the recommended land pattern for this inductor?
  The recommended land pattern for the 1255AY-2R2N=P3 is a rectangular pad with a size of 1.25mm x 1.25mm, with a non-solder mask defined (NSMD) pad shape.
• How do I handle the inductor's thermal considerations?
  The 1255AY-2R2N=P3 has a maximum operating temperature of 125°C. Ensure good airflow around the inductor and avoid placing heat-generating components nearby. Use a thermal via or thermal pad to dissipate heat if necessary.
• What is the inductor's self-resonant frequency (SRF)?
  The SRF of the 1255AY-2R2N=P3 is approximately 230 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?
  Yes, the 1255AY-2R2N=P3 is suitable for high-frequency applications up to several hundred MHz. However, be aware of the inductor's SRF and ensure that your operating frequency is below it to avoid unwanted resonances.
• How do I ensure the inductor's reliability in a high-reliability application?
  Follow Murata's recommended storage and handling procedures to prevent damage. Ensure proper soldering and cleaning processes, and consider using a conformal coating to protect the inductor from environmental factors.
