• General purpose power filtering

Fixed Inductors Procurement Notes

Verify the specific package dimensions (10.10mm x 11.60mm) against your PCB footprint requirements before ordering. Confirm that the 13 A current rating aligns with your thermal management strategy, as high-current operation may require adequate copper area or heatsinking. Ensure the operating temperature range of -55°C to +125°C meets your environmental specifications. Cross-reference the 16 mΩ DCR value to ensure voltage drop constraints are satisfied in your design.

Fixed Inductors Selection Notes

Select this component when high current capacity and low impedance are critical for power efficiency. The shielded design minimizes electromagnetic interference, making it suitable for dense layouts. Compare the 13 A rating against peak load requirements to prevent saturation. Consider the larger 10.10mm x 11.60mm footprint compared to standard chip inductors, which may impact board space but offers superior thermal performance.

Fixed Inductors Part Context

This part belongs to Central Technologies' fixed inductor lineup, specifically engineered for robust power electronics. It utilizes a metal mold construction to enhance durability and magnetic shielding. The product series targets applications requiring reliable performance under significant electrical loads, distinguishing it from lower-current general-purpose variants through its specialized high-current architecture.

Fixed Inductors Replacement Considerations

Direct substitutes must match the 4.7 µH inductance, 13 A current rating, and 16 mΩ DCR. Verify compatible packages such as 10x11.6mm SMD forms. Ensure replacement parts also offer shielded construction and similar temperature ratings (-55°C to +125°C). Consult manufacturer cross-reference lists for equivalent series from other vendors.
