103R-220J

Overview

The Delevan 103R-220J is an unshielded surface-mount RF inductor with a nominal inductance of 22 nH and a tolerance of ±5%. It features a maximum DC resistance of 108 mΩ and supports a maximum DC current of 950 mA. The component has a self-resonant frequency of 1 GHz and a minimum Q factor of 45. 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 high-frequency RF applications
• Compact 1010 surface-mount package design
• High self-resonant frequency capability

Applications

• RF circuit filtering
• Impedance matching networks
• High-frequency signal processing

Procurement Notes

Verify the specific manufacturer designation, as API Delevan assets may be managed by different entities. Confirm RoHS compliance status and lead times directly with authorized distributors or the current rights holder. Ensure the ordering suffix matches the required packaging format, such as reel quantities, to align with production requirements.

Selection Notes

Select this component when a low-inductance value near 22 nH is required for RF stages. The unshielded design necessitates careful PCB layout to minimize electromagnetic interference with adjacent traces. Verify that the 950 mA current rating meets the operational load and that the 1010 footprint fits the available board space constraints.

Part Context

This part belongs to the 103R series of fixed RF inductors manufactured by Delevan. These components are designed for general-purpose use in radio frequency circuits. The series offers various inductance values within a standardized 1010 package size, facilitating consistent assembly processes across different product designs requiring similar form factors.

Replacement Considerations

Cross-reference with other 103R series variants for different inductance values. Check for equivalent unshielded SMD RF inductors from other manufacturers offering identical 22 nH specifications and 1010 footprints. Ensure any substitute maintains comparable self-resonant frequency and current handling capabilities.
