103R-332KS

Overview

The Delevan 103R-332KS is an unshielded surface-mount RF inductor with a nominal inductance of 3.3 µH and a tolerance of ±10%. It features a maximum DC resistance of 1.4 Ω and supports a maximum DC current of 260 mA. The component has a minimum Q factor of 24 and operates within a temperature range of -55°C to +125°C. Its physical dimensions are 2.54 mm in length, 2.54 mm in width, and 1.91 mm in height.

Feature Summary

• Unshielded construction for minimal magnetic interference
• Surface-mount design optimized for RF applications
• Ferrite core material for stable inductance

Applications

• RF circuit filtering
• Impedance matching networks
• General-purpose RF signal processing

Procurement Notes

Verify the specific suffix 'KS' against the manufacturer's latest documentation to confirm packaging and compliance status. Ensure that the required operating current does not exceed the specified 260 mA limit during design validation. Cross-reference the thermal characteristics with the system's ambient conditions to prevent performance degradation.

Selection Notes

Select this component when an unshielded SMD inductor is required for RF frequencies around 3.3 µH. Consider the 2.54 x 2.54 mm footprint for PCB layout constraints. Evaluate the 1.4 Ω DC resistance impact on power loss relative to the 260 mA current rating. Compare Q factor requirements against alternative shielded or unshielded options in the same series.
