ER1537-12KR - API Delevan

ER1537-12KR Frequently Asked Questions (FAQs)

• What is the recommended PCB land pattern for ER1537-12KR?
  The recommended PCB land pattern for ER1537-12KR is a rectangular pad with dimensions of 3.8mm x 2.5mm, with a 1.3mm x 1.3mm thermal pad in the center. The pad should be solder-mask defined with a non-solder-mask defined (NSMD) pad.
• How do I handle the ER1537-12KR's thermal considerations?
  To handle thermal considerations, ensure good thermal conduction by using a thermal pad on the PCB, and consider using a thermal interface material (TIM) between the inductor and the PCB. Keep the inductor away from heat sources and ensure good airflow around the component.
• What is the ER1537-12KR's current rating derating curve?
  The current rating derating curve for ER1537-12KR is not explicitly provided in the datasheet. However, as a general guideline, the current rating derating curve for inductors follows a similar pattern to that of resistors, with a derating of 1-2% per degree Celsius above the rated temperature.
• Can I use the ER1537-12KR in a high-vibration environment?
  The ER1537-12KR is designed to meet the vibration requirements of IEC 60068-2-6, which includes vibration testing up to 10g acceleration. However, it's recommended to consult with API Delevan or perform additional testing to ensure the inductor meets the specific vibration requirements of your application.
• What is the ER1537-12KR's moisture sensitivity level (MSL)?
  The ER1537-12KR 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 onto a PCB.
