Fixed Inductors Procurement Notes

Verify the specific ordering suffix to ensure compliance with environmental regulations such as RoHS3 status. Confirm that the axial lead configuration matches the target PCB footprint and hole diameter requirements. Ensure the selected variant meets the required maximum DC current and resistance specifications for the intended circuit application. Cross-reference the manufacturer part number with official distributor catalogs to validate availability and authenticity before procurement.

Fixed Inductors Selection Notes

Select this component when a high-inductance value of 120 µH is required in a compact axial form factor. The low DC resistance of 13 Ohms makes it suitable for applications where power loss must be minimized within the specified current limit. Consider the self-resonant frequency of 12 MHz to ensure operation remains below the resonant point for effective filtering or choking behavior. The wide operating temperature range supports deployment in harsh environmental conditions.

Fixed Inductors Part Context

This component belongs to the 1025R series of molded unshielded RF coils manufactured by Delevan (API Delevan). The series is characterized by axial leads and iron cores, designed specifically for radio frequency applications. The 'G' suffix typically denotes a specific inductance value and tolerance combination within the product line, distinguishing it from other variants like the 1025R-70K which may have different tolerances or packaging configurations.

Fixed Inductors Replacement Considerations

Direct substitutes must match the 120 µH inductance, ±2% tolerance, and 13 Ohm DCR limits. Verify that alternative components support the same axial through-hole mounting style and 12 MHz self-resonant frequency. Ensure replacement parts maintain the 88 mA current rating and RoHS3 compliance. Generic equivalents may require validation of physical dimensions and thermal characteristics.
