Procurement Notes

Verify the complete part number including tolerance and packaging suffixes against the official datasheet before ordering. Ensure compatibility with automated placement equipment by checking reel specifications. Confirm thermal performance requirements align with the application's ambient temperature conditions.

Selection Notes

Select this component based on its specific current rating and saturation characteristics relative to the circuit design. Evaluate the physical dimensions to ensure they fit within the designated board area. Consider the operating frequency range to verify that core losses remain within acceptable limits for the intended switching regulator topology.

Part Context

This part belongs to the WE-HCI series of shielded wire-wound inductors. The series is characterized by its high current capability and low profile, addressing the need for efficient power management in modern electronic devices.
