103R-332J

Overview

The Delevan 103R-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 of 1.4 Ω and a rated current of 260 mA. The component measures 2.54 mm in length, 2.54 mm in width, and 1.91 mm in height. It exhibits a minimum Q factor of 24 and operates within a standard temperature range.

Feature Summary

• Unshielded construction for minimal magnetic interference
• Surface-mount design for automated PCB assembly
• Ferrite core material for stable RF performance

Applications

• RF signal filtering circuits
• Impedance matching networks
• General-purpose RF chokes

Procurement Notes

Verify the specific manufacturer source, as API Delevan assets may be held by other entities. Confirm RoHS compliance status directly with the supplier documentation. Ensure the package dimensions match the 103 series footprint requirements for your PCB layout to avoid mechanical fit issues during assembly.

Selection Notes

Select this component when an unshielded inductor is required for RF applications to reduce cost and size. The 3.3 µH value suits lower frequency RF filtering compared to nano-henry variants. Consider the 260 mA current rating against circuit load requirements. The 1.4 Ω DCR impacts power loss; verify thermal management needs for continuous operation at rated current.

Part Context

This part belongs to the 103/R series of fixed surface-mount inductors manufactured by Delevan. These components are designed for radio frequency applications requiring compact footprints. The series offers various inductance values with consistent physical dimensions, facilitating standardized board designs across different RF filter configurations.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided data. Cross-referencing requires verifying identical electrical parameters (3.3 µH, ±5%, 260 mA) and mechanical dimensions (2.54 x 2.54 x 1.91 mm). Unshielded type compatibility must be confirmed before substitution.
