103-822J

Overview

The Delevan 103-822J is a surface-mount RF inductor designed for high-frequency circuit applications. It features an unshielded wirewound construction with a nominal inductance of 8.2 uH and a tolerance of 5%. The component has a maximum DC current rating of 195 mA and a maximum DC resistance of 2.5 ohms. It operates within a temperature range of -55°C to +125°C, utilizing a ferrite core material. The physical dimensions are 2.54 mm in length, 2.54 mm in width, and 1.91 mm in height, conforming to the 1008 (2520 metric) package style.

Feature Summary

Unshielded wirewound design suitable for RF signal processing
Ferrite core construction providing stable inductance characteristics
Surface-mount technology optimized for automated PCB assembly

Applications

RF filtering circuits
Impedance matching networks
High-frequency signal conditioning

Procurement Notes

Verify the specific manufacturer designation, as API Delevan Inc. is also listed for this part number. Confirm RoHS compliance status, as conflicting data indicates non-compliance. Ensure the supplier provides official datasheets confirming the 2.5 ohm DC resistance value. Validate that the ferrite core material matches project requirements for thermal stability.

Selection Notes

Select this component when an unshielded SMD inductor with 8.2 uH nominal value is required. Consider the 195 mA current limit and 2.5 ohm resistance for power budget calculations. The 1008 package size fits standard RF layouts. Verify operating temperature needs against the -55°C to +125°C range before finalizing the design.

Part Context

This part belongs to the 103/R series of fixed RF inductors from Delevan. It shares the 1008 footprint with other variants like the 103-821HS but differs in inductance and resistance values. The series is characterized by unshielded wirewound designs intended for general RF applications where magnetic shielding is not strictly required.
