SRP1038WA-100M - Bourns

SRP1038WA-100M Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance?
  Bourns recommends a symmetrical PCB layout with a solid ground plane to minimize electromagnetic interference (EMI) and ensure optimal performance. A minimum of 2 oz copper thickness is recommended for the PCB.
• How do I handle the thermal considerations for this inductor?
  The SRP1038WA-100M has a maximum operating temperature of 125°C. Ensure good airflow around the inductor and consider using a heat sink if the ambient temperature exceeds 85°C. Also, follow the recommended derating curve for current handling at higher temperatures.
• What is the self-resonant frequency (SRF) of this inductor?
  The SRF of the SRP1038WA-100M is approximately 25 MHz. This is not explicitly stated in the datasheet, but it can be calculated using the inductance and capacitance values provided.
• Can I use this inductor in a high-voltage application?
  The SRP1038WA-100M has a maximum rated voltage of 100 V. While it can handle high currents, it is not designed for high-voltage applications. If you need an inductor for high-voltage use, consider a different part number or consult with Bourns' application engineers.
• How do I ensure the inductor is properly soldered to the PCB?
  Follow the recommended soldering profile and use a solder with a melting point above 217°C. Ensure the inductor is properly aligned with the PCB pads and use a sufficient amount of solder to fill the gap. Avoid applying excessive force or heat, which can damage the inductor.
