3339P-1-203LF Frequently Asked Questions (FAQs)

  • Bourns provides a recommended PCB layout and land pattern in their application notes. It's essential to follow these guidelines to ensure proper thermal management, minimize parasitic inductance, and optimize performance.
  • The 3339P-1-203LF is designed to minimize electromagnetic interference (EMI) and radio-frequency interference (RFI). The shielded construction and internal Faraday shield help to reduce electromagnetic radiation and susceptibility.
  • Bourns recommends derating the voltage by 10-15% to ensure reliable operation and prevent overheating. This means that for a 20V rated inductor, the maximum allowable voltage would be around 17-18V.
  • The 3339P-1-203LF is rated for operation up to 125°C. However, it's essential to consider the temperature coefficient of inductance and the potential for thermal runaway. Consult with Bourns or a thermal management expert for high-temperature applications.
  • The SRF of the 3339P-1-203LF is not explicitly stated in the datasheet. However, Bourns provides SRF data in their application notes or upon request. The SRF is typically in the range of 100-200 MHz for this inductor.
