103R-122J

Overview

The Delevan 103R-122J is a surface-mount RF inductor with an inductance of 1.2 µH and a tolerance of ±5%. It features a maximum DC resistance of 740 mΩ and a rated current of 360 mA. The component utilizes an unshielded design within a nonstandard two-lead SMD package, suitable for high-frequency applications.

Feature Summary

• Unshielded construction optimized for radio frequency signal processing
• Compact surface-mount footprint facilitating automated PCB assembly
• Fixed inductance value designed for impedance matching networks

Applications

• RF circuit filtering
• Impedance matching networks
• Signal conditioning in compact electronic devices

Procurement Notes

Verify the specific manufacturer designation, as API Delevan product lines may involve corporate transitions or naming conventions that differ from legacy identifiers. Confirm RoHS compliance status directly with the supplier documentation to ensure adherence to current environmental regulations for the specific production batch.

Selection Notes

Select this component when a fixed 1.2 µH inductance is required for RF applications without magnetic shielding constraints. Ensure the 360 mA current rating aligns with the circuit's operational limits and verify that the unshielded topology does not interfere with adjacent sensitive components on the board layout.

Part Context

This part belongs to the broader category of fixed surface-mount inductors manufactured by API Delevan. It serves as a passive component for managing electrical signals in high-frequency environments, distinct from shielded power inductors or general-purpose chokes found in other series.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-reference with other 1.2 µH unshielded SMD inductors only after verifying exact physical dimensions and electrical parameter tolerances against the original datasheet.
