103R-470K

Overview

The Delevan 103R-470K is a fixed surface-mount RF inductor with an inductance of 47 nH and a tolerance of ±10%. It features a maximum DC resistance of 145 mΩ and a rated current of 820 mA. The component utilizes a non-standard, two-lead package design with dimensions of 2.54 mm in length, 2.54 mm in width, and 1.91 mm in height. It operates within a temperature range of -55°C to +125°C and exhibits a minimum Q factor of 42.

Feature Summary

• Unshielded construction for specific RF signal path requirements
• Non-standard two-lead surface mount configuration
• Ferrite core material for stable high-frequency performance

Applications

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

Procurement Notes

Verify the specific package designation against official API Delevan documentation, as the 103R series may utilize distinct lead configurations compared to standard SMD footprints. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as historical data indicates potential variations in environmental certification across production batches.

Selection Notes

Select this component when a low-inductance value near 47 nH is required for RF applications. Ensure the PCB layout accommodates the unique two-lead form factor rather than standard quad-terminal SMD pads. Evaluate thermal management capabilities given the 820 mA current rating and the unshielded nature of the device.

Part Context

This part belongs to the API Delevan 103R series of fixed inductors. These components are designed for radio frequency applications where compact size and specific electrical characteristics are critical. The series typically offers various inductance values within a small footprint, catering to telecommunications and consumer electronics markets.

Replacement Considerations

Direct substitutes include other 47 nH RF inductors from manufacturers such as Coilcraft or Murata, provided they match the 145 mΩ DCR limit and support the required 820 mA current. Verify that alternative packages accommodate the same mechanical constraints.
