Fixed Inductors Procurement Notes

Verify the specific manufacturer part number against official Signal Transformer documentation to ensure authenticity. Confirm that the received components match the required electrical specifications, including the 6.8 µH inductance and 131 mΩ DCR limits. Check for RoHS compliance status and ensure the package type aligns with your board layout requirements before finalizing orders.

Fixed Inductors Selection Notes

Select this component when a 6.8 µH inductance is required with a high current rating of 1.55 A. Ensure the application can accommodate the 1 A saturation current limit to prevent performance degradation. Verify that the non-standard surface mount footprint fits the available PCB space and that the operating temperature range meets environmental conditions.
