105-181J

Overview

The Delevan 105-181J is a surface-mount RF inductor with an inductance of 180 nH and a tolerance of ±5%. It features a maximum DC current rating of 710 mA and a maximum DC resistance of 190 mOhms. The component has a minimum Q factor of 40 and a self-resonant frequency of 405 MHz. Its physical dimensions are 2.54 mm in length, 2.54 mm in width, and 1.91 mm in height. The device is unshielded and utilizes standard terminations for PCB mounting.

Feature Summary

• Unshielded SMD construction designed for RF applications
• High self-resonant frequency capability up to 405 MHz
• Compact non-standard footprint suitable for space-constrained designs

Applications

• RF circuit filtering
• Impedance matching networks
• General radio frequency signal processing

Procurement Notes

Verify the specific suffix designation when sourcing replacements, as variations such as 'JS' or 'K' may exist within the same base model family. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as historical data indicates potential discrepancies across different production batches and supplier listings. Ensure the selected variant matches the required termination style and packaging format for your assembly process.

Selection Notes

Select this component for applications requiring precise 180 nH inductance with tight 5% tolerance in high-frequency environments. The low DC resistance supports efficient power handling up to 710 mA without significant thermal loss. Consider the unshielded nature of the design regarding potential electromagnetic interference coupling in dense layouts. The small form factor allows for high-density board placement where larger shielded inductors cannot fit.
