ER1537-28JS - API Delevan

ER1537-28JS Frequently Asked Questions (FAQs)

• What is the recommended PCB land pattern for ER1537-28JS?
  The recommended PCB land pattern for ER1537-28JS is a rectangular pad with dimensions of 3.8 mm x 2.5 mm, with a 1.3 mm diameter hole in the center for the inductor's lead.
• Can I use ER1537-28JS in a high-temperature environment?
  While the ER1537-28JS is rated for operation up to 125°C, it's essential to derate the current rating according to the temperature derating curve provided in the datasheet to ensure reliable operation.
• How do I handle the ER1537-28JS inductor during PCB assembly to prevent damage?
  Handle the inductor by the body, avoiding touching the leads or the core. Use a vacuum pickup or tweezers to place the component on the PCB, and ensure the leads are not bent or stressed during assembly.
• What is the self-resonant frequency (SRF) of the ER1537-28JS inductor?
  The SRF of the ER1537-28JS is not explicitly stated in the datasheet, but it can be estimated using the inductance value and the Q factor. Typically, the SRF is around 100-200 MHz for this type of inductor.
• Can I use ER1537-28JS in a high-frequency application?
  While the ER1537-28JS is designed for general-purpose use, it may not be suitable for high-frequency applications (>100 MHz) due to its relatively low Q factor and high equivalent series resistance (ESR). Consider using a high-frequency inductor specifically designed for your application.
