103R-822F

Overview

The Delevan 103R-822F is an unshielded wirewound RF inductor designed for surface-mount technology (SMD) applications. It features a nominal inductance of 8.2 µH with a tight tolerance of ±1%. The component exhibits a maximum DC resistance of 2.5 Ohms and supports a maximum DC current of 195 mA. Key electrical characteristics include a minimum Q factor of 22 and a self-resonant frequency of 195 MHz. Physically, it conforms to the 1010 package dimensions, measuring 2.54 mm in length, 2.54 mm in width, and 1.91 mm in height.

Feature Summary

• Unshielded wirewound construction suitable for RF signal processing
• High precision inductance stability with ±1% tolerance
• Compact rectangular SMD form factor for dense PCB layouts

Applications

• RF circuit filtering
• Impedance matching networks
• General purpose RF inductors

Procurement Notes

Verify the specific manufacturer designation, as API Delevan products may be listed under API Delevan Inc. Confirm RoHS compliance status through official documentation, as historical data indicates variations. Ensure the ordering suffix matches the required packaging quantity, typically reels of 50 units for this series. Cross-reference the part number against current distributor catalogs to confirm availability and exact electrical specifications before procurement.

Selection Notes

Select this component when a precise 8.2 µH inductance is required for RF applications with strict tolerance limits. The unshielded design necessitates careful placement on the PCB to minimize electromagnetic interference with adjacent traces. Evaluate the 195 mA current rating against the circuit's operational requirements to ensure reliable performance without saturation. Consider the physical 1010 footprint constraints during the layout phase.

Part Context

This component belongs to the 103R series of fixed RF inductors manufactured by Delevan. The series is characterized by wirewound technology and unshielded designs optimized for radio frequency environments. Similar parts in the lineup include the 103R-152F and 103-561F, which share the same physical package but differ in inductance values and current ratings.

Replacement Considerations

Direct substitutes within the same series include the 103-822F, which shares identical electrical parameters and physical dimensions. Verify compatibility with existing PCB footprints and soldering profiles when transitioning between these variants.
