RCR875DNP-470L - Sumida

RCR875DNP-470L Frequently Asked Questions (FAQs)

• What is the recommended PCB layout and land pattern for optimal performance?
  The recommended PCB layout and land pattern can be found in the Sumida Corporation's application note AN-1401, which provides guidelines for optimal performance and reduced electromagnetic interference (EMI).
• How does the inductor perform in high-temperature environments?
  The RCR875DNP-470L is rated for operation up to 125°C, but it's recommended to derate the current rating by 1.5% per degree Celsius above 80°C to ensure reliable operation. Consult the datasheet and Sumida's reliability handbook for more information.
• What is the self-resonant frequency (SRF) of the inductor?
  The SRF of the RCR875DNP-470L is not explicitly stated in the datasheet, but it can be estimated using the inductance value and the Q factor. A rough estimate can be made using the formula SRF ≈ (1 / (2 * π * √(L * C))), where L is the inductance and C is the parasitic capacitance. However, it's recommended to consult with Sumida's application engineers for a more accurate calculation.
• Can the inductor be used in a high-vibration environment?
  The RCR875DNP-470L is designed to meet the vibration requirements of IEC 60068-2-6, but it's recommended to consult with Sumida's application engineers to ensure the inductor meets the specific vibration requirements of your application.
• What is the recommended storage and handling procedure for the inductor?
  The RCR875DNP-470L should be stored in a dry, clean environment, away from direct sunlight and moisture. It's recommended to follow the EIA-480 standard for storage and handling of electronic components to prevent damage and ensure reliability.
