ETH1-230LB - COILCRAFT

ETH1-230LB Frequently Asked Questions (FAQs)

• What is the recommended PCB land pattern for the ETH1-230LB?
  Coilcraft provides a recommended PCB land pattern in their application notes, which includes a rectangular pad with a size of 0.25 x 0.35 inches (6.4 x 8.9 mm) and a thermal relief pattern to ensure good thermal conduction.
• How do I handle the ETH1-230LB's sensitivity to PCB layout and proximity to other components?
  To minimize the impact of PCB layout and proximity to other components, keep the ETH1-230LB at least 0.1 inches (2.5 mm) away from other components, and avoid running high-frequency signals or power traces near the inductor. Use a solid ground plane under the inductor to reduce electromagnetic interference (EMI).
• What is the maximum operating temperature range for the ETH1-230LB?
  The ETH1-230LB has an operating temperature range of -40°C to +125°C, but the inductor's characteristics may vary outside the recommended operating temperature range of -20°C to +100°C.
• How do I ensure the ETH1-230LB meets my application's electromagnetic compatibility (EMC) requirements?
  To ensure EMC compliance, use a shielded enclosure, keep the ETH1-230LB away from radiating sources, and use a common-mode choke or other EMI filtering components as needed. Follow good PCB layout practices, such as using a solid ground plane and minimizing loop areas.
• What is the ETH1-230LB's tolerance for overvoltage and overcurrent?
  The ETH1-230LB is designed to withstand overvoltage and overcurrent conditions, but it is still important to follow the recommended voltage and current ratings to prevent damage. The inductor can withstand voltage surges up to 1.5 times the rated voltage for a short duration, but prolonged exposure may cause damage.
