Procurement Notes

Verify the specific suffix designation against official API Delevan documentation to confirm exact electrical tolerances and packaging configurations. Ensure that the ordering information matches the required lead time and minimum order quantities specified by authorized distributors. Cross-reference the manufacturer part number with the latest datasheet revisions to avoid discrepancies in component specifications.

Selection Notes

Select this component when an unshielded inductor is required to prevent magnetic field interaction with nearby sensitive components. The 6.8 µH value and 210 mA rating must align with the circuit's impedance and current requirements. Consider the self-resonant frequency limits to ensure performance stability within the intended operational bandwidth without parasitic resonance issues.

Part Context

This part belongs to the 103/R series of fixed inductors from API Delevan. The series offers various inductance values optimized for RF applications. The 103R-682G specifically addresses needs for moderate inductance with tight tolerance in compact surface-mount form factors, distinguishing it from shielded or through-hole alternatives in the same product line.

Replacement Considerations

Consult official substitution guides for equivalent unshielded SMD inductors with matching 6.8 µH ±2% specifications. Verify that alternative parts maintain similar Q-factor and self-resonant frequency characteristics to ensure circuit performance parity.
