PM1812-470J-RC - Bourns

PM1812-470J-RC Frequently Asked Questions (FAQs)

• What is the recommended land pattern for the PM1812-470J-RC?
  The recommended land pattern for the PM1812-470J-RC can be found in the Bourns Application Note S-8151, which provides guidelines for surface mount assembly and layout considerations.
• How do I handle the PM1812-470J-RC during reflow soldering?
  During reflow soldering, it's essential to follow the recommended reflow profile provided in the datasheet. The component should be placed on a solder paste layer with a thickness of 0.1 mm to 0.2 mm, and the peak reflow temperature should not exceed 260°C.
• Is the PM1812-470J-RC suitable for high-frequency applications?
  While the PM1812-470J-RC is a general-purpose inductor, it's not optimized for high-frequency applications. For high-frequency designs, Bourns recommends using their high-frequency inductor series, such as the SRP1035A or SRN1065A.
• Can I use the PM1812-470J-RC in a high-temperature environment?
  The PM1812-470J-RC is rated for operation up to 125°C. While it can tolerate short-term excursions up to 150°C, prolonged exposure to high temperatures may affect its performance and reliability. For high-temperature applications, consider using Bourns' high-temperature inductor series, such as the PHF-1812 series.
• How do I determine the equivalent series resistance (ESR) of the PM1812-470J-RC?
  The ESR of the PM1812-470J-RC can be calculated using the formula provided in the datasheet: ESR = (DCR x f) / (Q x π), where DCR is the DC resistance, f is the frequency, and Q is the quality factor. Alternatively, you can consult Bourns' application notes or contact their technical support for guidance.
