SD25-100-R - Eaton

SD25-100-R Frequently Asked Questions (FAQs)

• What is the recommended PCB land pattern for the SD25-100-R?
  The recommended PCB land pattern for the SD25-100-R can be found in the Coiltronics application note AN-001, which provides detailed guidelines for PCB layout and footprint design.
• How do I handle the SD25-100-R's thermal considerations in my design?
  The SD25-100-R has a maximum operating temperature of 125°C. To ensure reliable operation, it's essential to consider thermal management in your design, such as providing adequate airflow, using thermal vias, and selecting a suitable PCB material with high thermal conductivity.
• What is the self-resonant frequency (SRF) of the SD25-100-R?
  The self-resonant frequency (SRF) of the SD25-100-R is not explicitly stated in the datasheet. However, according to Coiltronics' application note AN-002, the SRF can be estimated using the inductor's inductance value and the parasitic capacitance. For the SD25-100-R, the estimated SRF is around 150-200 MHz.
• Can I use the SD25-100-R in a high-vibration environment?
  The SD25-100-R is designed to meet the vibration requirements of IEC 60068-2-6, which specifies a vibration amplitude of 10 G peak acceleration. However, it's essential to consult with Coiltronics or perform additional testing to ensure the inductor's reliability in your specific high-vibration application.
• How do I select the correct inductor for my specific application?
  To select the correct inductor, consider factors such as the operating frequency, current rating, inductance value, and physical size constraints. Coiltronics provides a product selection guide that can help you narrow down the options based on your specific requirements.
