103R-183J

Overview

The Delevan 103R-183J is a fixed surface-mount RF inductor from the 103(R) series. It features an 18 µH nominal inductance with ±5% tolerance and a maximum DC resistance of 5.8 Ohms. The component supports a maximum DC current of 130 mA and utilizes an unshielded ferrite core construction. Its physical dimensions are 2.54 mm x 2.54 mm with a height of 1.91 mm, designed for standard PCB mounting.

Feature Summary

• Unshielded design utilizing ferrite core material for RF applications
• Surface mount package with non-standard two-lead configuration
• Rated for operation within a temperature range of -55°C to +125°C

Applications

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

Procurement Notes

Verify component availability status prior to integration, as supply chain constraints may affect lead times. Confirm RoHS compliance documentation matches specific project requirements. Ensure ordering suffixes align with required packaging formats such as cut tape or reel quantities specified by the manufacturer.

Selection Notes

Select this component when an unshielded 18 µH inductor is required for space-constrained RF designs. The 130 mA current rating suits low-power signal paths rather than high-current power stages. Consider thermal management capabilities given the 5.8 Ohm DC resistance and small footprint dimensions.
