Fixed Inductors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct tolerance and packaging specifications. Confirm that the requested quantity aligns with standard factory pack quantities defined by Bourns Inc. Cross-reference the date code and lot information upon receipt to maintain supply chain traceability and quality assurance standards.

Fixed Inductors Selection Notes

Select this component when a low-inductance value near 470 nH is required for high-frequency switching applications. Ensure the circuit design accounts for the 3.2 A RMS and 3.8 A saturation limits to prevent performance degradation. The 1919 footprint must be validated against the target PCB layout constraints to guarantee proper mechanical fit and thermal dissipation requirements are met.
