Procurement Notes

Verify the manufacturer part number against official Delevan documentation to confirm specifications. Ensure the ordering suffix matches the required tolerance and packaging configuration. Cross-reference technical parameters such as inductance, current rating, and physical dimensions with the specific datasheet before procurement to avoid compatibility issues.

Selection Notes

Select this component when a 1 µH inductance value is required for RF circuits. Consider the 425 mA current rating and 540 mΩ resistance for power handling needs. The unshielded design requires layout consideration to prevent magnetic coupling with nearby components. Verify that the operating frequency remains below the 145 MHz self-resonant point for effective performance.
