103R-562G

Overview

The Delevan 103R-562G is an unshielded surface-mount RF inductor with a nominal inductance of 5.6 µH and a tolerance of ±2%. It features a maximum DC resistance of 2 Ohms and supports a maximum DC current of 220 mA. The component has a Q factor of at least 22 and a self-resonant frequency of 30 MHz. 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 general-purpose RF applications
• Surface-mount design with standard terminations
• High-Q performance suitable for radio frequency circuits

Applications

• RF signal processing
• Impedance matching networks
• Filtering circuits

Procurement Notes

Verify the specific suffix 'G' indicates the required tolerance level, as other variants like 'KS' exist within the same series. Confirm package compatibility with automated placement equipment. Ensure the operating temperature range meets system requirements. Cross-reference datasheets to confirm electrical parameters match the specific revision.

Selection Notes

Select this component when a 5.6 µH inductance with tight ±2% tolerance is required for RF stages. Compare against the 103R-562KS variant if a wider 10% tolerance is acceptable for cost or availability reasons. Evaluate the 220 mA current rating against peak circuit loads to prevent saturation.

Part Context

This part belongs to the Delevan 103R series of chip RF inductors. These components are designed for high-frequency applications where size and performance are critical. The series offers various inductance values and tolerance options to suit different circuit requirements.

Replacement Considerations

The 103R-562KS is a direct alternative with identical form factor but a 10% tolerance instead of 2%. Verify that the looser tolerance does not impact circuit stability before substitution.
