105R-332J

Overview

The Delevan 105R-332J is an unshielded surface-mount RF inductor with a nominal inductance of 3.3 µH and a tolerance of ±5%. It features a maximum DC resistance (DCR) of 2.2 Ohms and a rated current of 210 mA. The component utilizes a ferrite core and operates within a temperature range of -55°C to 125°C. Key electrical parameters include a self-resonant frequency of 62 MHz and a Q factor of 30 at 7.9 MHz. The package dimensions are non-standard, with a maximum seated height of 0.075 inches (1.91 mm).

Feature Summary

• Unshielded surface-mount construction for high-frequency applications.
• Ferrite core material providing stable inductance characteristics.
• High self-resonant frequency of 62 MHz suitable for RF circuits.

Applications

• RF filter networks
• Impedance matching circuits
• General-purpose RF signal processing

Procurement Notes

Verify the specific manufacturer source, as API Delevan assets have undergone corporate restructuring. Confirm RoHS compliance status and lifecycle stage, as some sources indicate this part may be obsolete or discontinued. Ensure the supplier provides valid traceability documentation for the original API Delevan manufacturing origin before finalizing procurement orders.

Selection Notes

Select this component when a 3.3 µH unshielded inductor with low current handling (210 mA) is required for RF applications. Compare against the 1008R-332J for smaller footprint options or the 1812R-332J for higher current capacity. Verify that the 2.2 Ohm DCR meets the circuit's power loss requirements and that the non-standard package fits the PCB layout constraints.

Part Context

The 105R-332J belongs to the Delevan R series of unshielded surface-mount inductors. These components are designed for radio frequency applications where shielding is not required. The series typically offers various inductance values with consistent physical footprints, though the 105R variant uses a specific non-standard package size distinct from the metric-based 1008R or 1812R series.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided data. Due to the potential obsolete status of this specific Delevan part number, engineers should consult official distributor lifecycle notices or contact the manufacturer directly for recommended cross-reference alternatives.
