Fixed Inductors Procurement Notes

Verify the specific ordering suffix to ensure the correct inductance value and tolerance match the design requirements. Confirm that the radial vertical cylinder package and through-hole mounting style are compatible with the target PCB layout. Check the maximum DC resistance specification against thermal management constraints. Ensure the 5.5 A current rating meets the operational load demands of the application without saturation.

Fixed Inductors Selection Notes

Select this component when an unshielded radial inductor with high current capacity is required. The 2.2 mH value suits applications needing significant impedance at lower frequencies. Consider the large 1.600-inch diameter for adequate spacing on the assembly board. The through-hole technology ensures mechanical stability for heavy components. Evaluate the 338 milliohm resistance for efficiency losses in the power path.

Fixed Inductors Part Context

This part belongs to the RL-1256 series of fixed inductors from Renco Electronics, Inc. The series includes various models with different inductance values and current ratings, all sharing the radial vertical cylinder form factor. These components are categorized as power line chokes, indicating their use in managing electrical noise and stabilizing power delivery in demanding environments.

Fixed Inductors Replacement Considerations

Direct substitutes must match the 2.2 mH inductance, 5.5 A current rating, and radial vertical package. Verify that any alternative component maintains the same 338 milliohm maximum DC resistance and ±10% tolerance. Ensure the replacement fits the 1.600-inch diameter constraint and supports through-hole mounting.
