4609X-101-471LF - Bourns

4609X-101-471LF Frequently Asked Questions (FAQs)

• What is the recommended PCB layout and land pattern for optimal performance?
  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.
• How does the inductor handle high-frequency noise and EMI?
  The 4609X-101-471LF is designed to minimize electromagnetic interference (EMI) and radio-frequency interference (RFI). Its shielded construction and internal Faraday shield help to reduce electromagnetic radiation and susceptibility.
• What is the maximum allowable voltage derating for this inductor?
  Bourns recommends derating the voltage by 10-15% to ensure reliable operation and prevent overheating. For the 4609X-101-471LF, the maximum allowable voltage derating would be around 90-95% of the rated voltage.
• Can I use this inductor in a high-temperature environment?
  The 4609X-101-471LF 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.
• What is the recommended storage and handling procedure for these inductors?
  Bourns recommends storing the inductors in their original packaging, away from direct sunlight, moisture, and extreme temperatures. Handle the components by the body, avoiding touching the leads or core to prevent damage or contamination.
