Fixed Inductors Procurement Notes

Verify the specific suffix (H) against official manufacturer documentation to confirm tolerance and packaging specifications. Ensure compatibility with standard SMD reflow processes. Confirm RoHS compliance status through the latest datasheet or supplier certification before integration into production lines.

Fixed Inductors Selection Notes

Select this component when a high-inductance value with tight tolerance is required for RF shielding applications. Consider the 178 mA current limit and 9.5 Ohm resistance for power loss calculations. Evaluate the 5.7 MHz self-resonant frequency to ensure operation remains below the resonant point for intended signal frequencies.

Fixed Inductors Part Context

This part belongs to the S4924R series of fixed RF inductors manufactured by API Delevan. The series offers various inductance values within a consistent 13.21 x 6.35 x 5.84 mm package footprint.
