1276AS-H-2R2M=P2 - Murata Electronics

1276AS-H-2R2M=P2 Frequently Asked Questions (FAQs)

• What is the recommended land pattern for this inductor?
  The recommended land pattern for the 1276AS-H-2R2M=P2 inductor is a rectangular pad with a size of 2.5mm x 1.6mm, with a non-solder mask defined (NSMD) pad shape. This ensures proper soldering and minimizes the risk of solder bridging.
• How do I handle the inductor's thermal considerations?
  The 1276AS-H-2R2M=P2 inductor has a maximum operating temperature of 125°C. To ensure reliable operation, it's essential to consider thermal management in your design. This includes providing adequate airflow, using thermal vias, and selecting a suitable PCB material with high thermal conductivity.
• What is the inductor's self-resonant frequency (SRF)?
  The self-resonant frequency (SRF) of the 1276AS-H-2R2M=P2 inductor is approximately 150 MHz. This is the frequency at which the inductor's impedance peaks due to the resonance between the inductance and the parasitic capacitance.
• Can I use this inductor in a high-frequency application?
  While the 1276AS-H-2R2M=P2 inductor is suitable for high-frequency applications, its performance may degrade above 100 MHz due to the skin effect and proximity effect. For frequencies above 100 MHz, it's recommended to consider alternative inductor options with lower parasitic capacitance and higher self-resonant frequencies.
• How do I ensure the inductor's reliability in a high-vibration environment?
  To ensure the reliability of the 1276AS-H-2R2M=P2 inductor in a high-vibration environment, it's essential to follow proper mounting and soldering techniques. Additionally, consider using a vibration-resistant mounting method, such as a screw-down or adhesive mounting, and ensure the PCB is designed to withstand the expected vibration levels.
