1235AS-H-1R2N=P3 - Murata Electronics

1235AS-H-1R2N=P3 Frequently Asked Questions (FAQs)

• What is the recommended land pattern for this inductor?
  The recommended land pattern for the 1235AS-H-1R2N=P3 inductor is a rectangular pad with a size of 1.2mm x 1.4mm, 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 1235AS-H-1R2N=P3 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 1235AS-H-1R2N=P3 inductor is approximately 150 MHz. This is the frequency at which the inductor's impedance peaks due to the resonance between the inductor's inductance and its parasitic capacitance.
• Can I use this inductor in a high-frequency application?
  While the 1235AS-H-1R2N=P3 inductor is suitable for high-frequency applications, its performance may degrade above 100 MHz due to its self-resonant frequency. For frequencies above 100 MHz, it's recommended to consider alternative inductors with a higher SRF or to use impedance matching techniques to optimize the inductor's performance.
• How do I ensure the inductor's reliability in a humid environment?
  To ensure the reliability of the 1235AS-H-1R2N=P3 inductor in a humid environment, it's essential to follow proper storage and handling procedures. This includes storing the components in a dry, cool place, and using moisture-resistant packaging. Additionally, consider applying a conformal coating to the PCB to protect the inductor from moisture ingress.
