Fixed Inductors Procurement Notes

Verify the specific ordering suffix 'JL' against the manufacturer's official datasheet to confirm lead frame material and plating specifications. Ensure that the selected variant matches the required moisture sensitivity level and reflow soldering profile for your assembly process. Cross-reference the exact part number with authorized distributors to avoid counterfeit components.

Fixed Inductors Selection Notes

Select this component when a compact 1812 footprint is required for 100 µH shielding. Consider the 8 Ω DC resistance for voltage drop calculations in low-current paths. Evaluate the self-resonant frequency limits if operating near the upper end of the specified bandwidth. Confirm thermal management requirements align with the 100°C maximum operating limit.

Fixed Inductors Part Context

This part belongs to the Bourns CM453232 series of shielded power inductors. The series offers various inductance values within the same 4.5 x 3.2 x 3.2 mm envelope, allowing designers to standardize board space while adjusting circuit parameters. It targets applications requiring reliable SMT integration for consumer and industrial electronics.

Fixed Inductors Replacement Considerations

Consult the official Bourns cross-reference guide for verified substitutes. Direct replacements must match the 100 µH value, 1812 package dimensions, and shielding type.
