The physical dimensions are approximately 2.54 mm in length, 2.54 mm in width, and 1.91 mm in height.

Feature Summary

• Unshielded construction for specific electromagnetic interference requirements
• Designed for high-frequency radio frequency circuit integration
• Surface mount technology compatible for automated PCB assembly

Applications

• RF signal filtering circuits
• Impedance matching networks
• High-frequency choke applications

Procurement Notes

Verify the manufacturer designation carefully, as API Delevan components may be listed under various legacy naming conventions. Confirm RoHS compliance status directly with the supplier, as historical data indicates variations. Ensure the specific suffix matches the required tolerance and packaging format for your production line requirements.

Selection Notes

Select this component when an unshielded inductor is required to minimize parasitic capacitance effects in sensitive RF paths. Compare the 79 mA current rating against peak load conditions to prevent saturation. Consider the 24 MHz self-resonant frequency limit to ensure adequate impedance characteristics at the target operating frequency.

Part Context

This part belongs to the Delevan fixed inductor family, specifically optimized for radio frequency environments. It utilizes a chip-style SMD package typical for compact electronic designs. The product line emphasizes stability in high-frequency signal processing applications where shielding might introduce unwanted coupling.

Replacement Considerations

Cross-reference with other 15 µH unshielded SMD inductors from the same manufacturer series. Verify that substitute parts maintain the 24 MHz self-resonant frequency and 4.2 Ohm DC resistance limits to ensure circuit performance parity.
