105-152F

Overview

The Delevan 105-152F is an unshielded surface-mount RF inductor with a nominal inductance of 1.5 uH and a tolerance of 1%. It features a maximum DC current rating of 280 mA and a maximum DC resistance of 1.2 Ohms. The component has a minimum Q factor of 25 and a self-resonant frequency of 100 MHz. Its physical dimensions are 2.54 mm in length, 2.54 mm in width, and 1.91 mm in height. It utilizes standard terminations for PCB mounting.

Feature Summary

• Unshielded construction suitable for RF applications
• Surface-mount design for automated PCB assembly
• High precision 1% inductance tolerance

Applications

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

Procurement Notes

Verify the manufacturer designation carefully, as API Delevan components may be listed under All Sensors or API Delevan Inc. Confirm RoHS compliance status, as documentation indicates non-compliance (N). Ensure the specific suffix matches the required tolerance and packaging configuration for your production line requirements.

Selection Notes

Select this component when a compact, unshielded SMD inductor is required for RF frequencies near 100 MHz. Consider the 280 mA current limit and 1.2 Ohm DCR for power handling constraints. Compare against the 103-152F if different mechanical footprints or slightly different electrical characteristics are needed for the same inductance value.

Part Context

This part belongs to the 105 series of fixed RF inductors from Delevan. It is designed for high-frequency applications where space is limited. The series offers various inductance values with tight tolerances, catering to precise RF circuit design needs in consumer electronics and communication devices.

Replacement Considerations

The 105-152KS is a variant with 10% tolerance instead of 1%, sharing similar electrical parameters but differing in precision. Other 1.5 uH options like the 103-152F offer different physical dimensions and current ratings.
