1227AS-H-1R5N=P2 - Murata Electronics

1227AS-H-1R5N=P2 Frequently Asked Questions (FAQs)

• What is the recommended land pattern for this inductor?
  The recommended land pattern for the 1227AS-H-1R5N=P2 inductor is a rectangular pad with a size of 1.2mm x 0.7mm, with a non-solder mask defined (NSMD) pad shape. This can be found in the Murata Land Pattern Recommendation document.
• How do I handle the inductor's thermal considerations?
  The 1227AS-H-1R5N=P2 inductor has a maximum operating temperature of 125°C. To ensure reliable operation, it's essential to consider thermal management by providing adequate heat dissipation, such as using a heat sink or thermal vias, and avoiding high ambient temperatures.
• What is the inductor's self-resonant frequency (SRF)?
  The self-resonant frequency (SRF) of the 1227AS-H-1R5N=P2 inductor is not explicitly stated in the datasheet. However, based on similar inductors from Murata, the SRF is typically in the range of 100-200 MHz. It's recommended to consult with Murata's application engineers or perform your own measurements to determine the SRF for your specific application.
• Can I use this inductor in a high-vibration environment?
  The 1227AS-H-1R5N=P2 inductor is designed to meet the vibration requirements of IEC 60068-2-6, which includes vibration testing up to 10G. However, it's essential to evaluate the inductor's performance in your specific application and environment to ensure reliable operation.
• What is the inductor's moisture sensitivity level (MSL)?
  The 1227AS-H-1R5N=P2 inductor has a moisture sensitivity level (MSL) of 1, which means it can withstand a maximum of 30 days in a humidity-controlled environment before being soldered. It's essential to follow proper storage and handling procedures to prevent moisture-related damage.
