SD53-470-R - Eaton

SD53-470-R Frequently Asked Questions (FAQs)

• What is the recommended PCB land pattern for the SD53-470-R?
  The recommended PCB land pattern for the SD53-470-R can be found in the Coiltronics' application note AN-001, which provides detailed guidelines for PCB layout and footprint design.
• How does the SD53-470-R perform in high-temperature environments?
  While the datasheet specifies an operating temperature range of -40°C to +125°C, Coiltronics recommends derating the inductor's current rating by 1.5% per degree Celsius above 80°C to ensure reliable operation in high-temperature environments.
• Can the SD53-470-R be used in high-frequency applications above 1 MHz?
  Yes, the SD53-470-R can be used in high-frequency applications above 1 MHz, but it's essential to consider the inductor's self-resonant frequency (SRF) and ensure that the operating frequency is below the SRF to avoid unwanted resonances and losses.
• What is the recommended soldering profile for the SD53-470-R?
  Coiltronics recommends a soldering profile with a peak temperature of 260°C and a dwell time of 10-15 seconds to ensure reliable solder joints and prevent damage to the inductor.
• Are there any specific handling and storage guidelines for the SD53-470-R?
  Yes, Coiltronics recommends handling the SD53-470-R with care to avoid mechanical stress, and storing them in a dry, cool place to prevent moisture absorption and damage.
