- Surface mount design for automated PCB assembly
- High current handling capability for power applications
Applications
- Power supply filtering
- RF and microwave circuit integration
- Aerospace and defense electronic systems
Procurement Notes
Verify the exact physical dimensions and footprint compatibility against your PCB layout before ordering, as the package is classified as nonstandard. Confirm that the 1.81 A current rating meets your specific load requirements. Ensure the shielded toroidal form factor fits within your enclosure constraints. Cross-reference the datasheet for thermal performance limits under continuous operation conditions.
Selection Notes
Select this component when a shielded surface mount inductor is required for power applications. The 50 µH value and 1.81 A rating define its operational range. Consider the nonstandard package size during mechanical design. Verify RoHS compliance if lead-free soldering processes are mandated for your production line.
Part Context
Gowanda Electronics specializes in high-performance magnetic components for demanding sectors including aerospace, defense, and medical industries. The 030AT series represents their surface mount toroidal inductor line, engineered for reliability in critical RF and power environments where standard components may fail.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Due to the nonstandard package and specific shielding characteristics, direct pin-to-pin replacements cannot be guaranteed without detailed engineering validation.
