103R-182J

Overview

The Delevan 103R-182J is an unshielded surface-mount RF inductor with a nominal inductance of 1.8 µH and a tolerance of ±5%. It features a ferrite core and standard SMD/SMT terminations, housed in a compact 2.54 mm x 2.54 mm x 1.91 mm footprint. The component supports a maximum DC current of 325 mA and exhibits a maximum DC resistance of 0.92 Ω. Designed for radio frequency applications, it operates within a temperature range of -55°C to +125°C.

Feature Summary

• Unshielded construction suitable for general-purpose RF circuits
• Ferrite core material for stable inductive performance
• Surface-mount design optimized for PCB integration

Applications

• Radio Frequency (RF) signal processing
• General purpose inductive filtering
• SMD circuit board mounting

Procurement Notes

Verify the specific manufacturer designation, as API Delevan components may be sourced under various legacy or updated naming conventions. Confirm RoHS compliance status directly with the supplier documentation, as historical data indicates variations across different production batches and series revisions. Ensure the unshielded characteristic aligns with your electromagnetic interference requirements before finalizing procurement.

Selection Notes

Select this component when an unshielded RF inductor with a 1.8 µH value is required for space-constrained designs. The 1010-style footprint allows for dense PCB layouts. Consider the 325 mA current rating and 0.92 Ω resistance to ensure compatibility with your circuit's power handling needs. Verify that the lack of shielding does not interfere with adjacent sensitive components in your layout.

Part Context

This part belongs to the 103/R series of fixed inductors manufactured by API Delevan. These components are specifically engineered for radio frequency applications requiring small form factors. The series utilizes ferrite cores to achieve stable inductance values in unshielded packages, distinguishing them from shielded power inductor variants found in other product lines.
