103R-822HS

Overview

The Delevan 103R-822HS is an unshielded surface-mount RF inductor with a nominal inductance of 8.2 µH and a tolerance of ±3%. It features a maximum DC resistance of 2.5 Ω and a minimum Q factor of 30, with a self-resonant frequency of 20 MHz. The component supports a maximum DC current of 195 mA and operates within a temperature range of -55°C to +125°C. Its physical dimensions are 2.92 mm in length, 2.66 mm in width, and 2.41 mm in height.

Feature Summary

• Unshielded construction for minimal magnetic interference
• Temperature-stable performance across industrial ranges
• Standard SMD/SMT termination for PCB mounting

Applications

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

Procurement Notes

Verify the specific manufacturer designation, as API Delevan components may be sourced under either API or Delevan branding. Confirm RoHS compliance status directly with the supplier documentation, as availability varies by region. Ensure the ordering suffix matches the required reel quantity specifications for automated assembly processes.

Selection Notes

Select this component when an unshielded RF inductor with 8.2 µH nominal value is required. Consider the 195 mA current limit and 2.5 Ω DC resistance against circuit load requirements. Verify that the 20 MHz self-resonant frequency aligns with the target operating band to prevent harmonic distortion.

Part Context

This part belongs to the 103/R series of fixed RF inductors designed for surface-mount applications. It utilizes a phenolic core material and rectangular construction typical of general-purpose RF chokes. The series provides standard terminal configurations suitable for high-volume PCB assembly workflows.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-reference with other 103R series variants only if electrical parameters match exactly.
