1025R-86K - API Delevan

1025R-86K Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance?
  API Delevan recommends a symmetrical PCB layout with a solid ground plane to minimize radiation and ensure optimal performance. A minimum of 0.5 mm clearance around the inductor is recommended to prevent electromagnetic interference.
• How do I handle the inductor's thermal considerations?
  The 1025R-86K has a maximum operating temperature of 125°C. Ensure good airflow around the inductor, and consider using a thermal pad or heat sink if the ambient temperature exceeds 85°C. Derate the inductor's current rating by 1.5% per degree Celsius above 85°C.
• What is the inductor's self-resonant frequency (SRF)?
  The SRF of the 1025R-86K is not explicitly stated in the datasheet, but it can be estimated using the inductance value and the Q factor. A rough estimate is around 100-150 MHz. However, it's recommended to consult with API Delevan's application engineers for a more accurate calculation.
• Can I use the 1025R-86K in a high-vibration environment?
  Yes, the 1025R-86K is designed to withstand vibrations up to 10 G peak acceleration. However, it's essential to ensure the inductor is properly secured to the PCB using the recommended mounting method to prevent mechanical stress.
• What is the inductor's moisture sensitivity level (MSL)?
  The 1025R-86K has an MSL rating of 1, which means it can withstand normal humidity levels without special handling. However, it's still recommended to follow standard moisture-sensitive device handling procedures to prevent damage during assembly and storage.
