108R-153J

Overview

The Delevan 108R-153J is a fixed surface-mount inductor from the 108R series, featuring a ferrite core and unshielded construction. It provides an inductance of 15 µH with a tolerance of ±5%. The component has a maximum DC resistance of 4.2 Ohms and a current rating of 79 mA. Key electrical characteristics include a Q factor of 32 minimum at 2.5 MHz and a self-resonant frequency of 24 MHz. It operates within a temperature range of -55°C to 125°C.

Feature Summary

• Unshielded ferrite core design for RF applications
• Surface mount packaging for automated assembly
• High self-resonant frequency capability

Applications

• RF circuit filtering
• Impedance matching networks
• Signal processing circuits

Procurement Notes

Verify the manufacturer part number against official API Delevan documentation to ensure authenticity. Confirm that the specific suffix matches the required tolerance and performance specifications. Check RoHS compliance status as indicated in the latest datasheet revisions. Ensure storage conditions align with the specified operating temperature range to maintain component integrity prior to installation.

Selection Notes

Select this component when a 15 µH inductance with low current handling (79 mA) is required for RF environments. The unshielded design necessitates careful PCB layout to minimize electromagnetic interference with adjacent traces. Compare the 4.2 Ohm DCR against circuit loss requirements. Consider the 24 MHz self-resonant limit to ensure operation remains below the resonant frequency for effective inductive behavior.

Part Context

This part belongs to the 108R series of fixed inductors manufactured by API Delevan. The series offers various inductance values in a compact SMD form factor. The 108R-153J specifically targets high-frequency applications where moderate inductance and low current capacity are sufficient. It complements other components in passive filter and tuning network designs.

Replacement Considerations

Direct substitutes must match the 15 µH inductance, 79 mA current rating, and 4.2 Ohm DCR. Verify package dimensions and pin compatibility. Cross-reference with API Delevan's official replacement guides or equivalent series from other manufacturers ensuring identical electrical parameters and thermal ratings.
