Arrays, Signal Transformers Procurement Notes

Verify the specific suffix '-R' indicates reel packaging configuration. Confirm RoHS3 compliance status for environmental regulations. Check lead times as manufacturing may vary. Ensure the part number matches the exact electrical requirements for series/parallel operation before ordering.

Arrays, Signal Transformers Selection Notes

Select this component when dual inductors are required in a single footprint. Compare DCR values against thermal constraints. Verify that the 630 mA parallel rating meets load demands. Consider the 5.97 mm height for board clearance. Ensure compatibility with automated SMD placement equipment.

Arrays, Signal Transformers Part Context

Part of the CTX family, specifically the OCTA-PAC PLUS line. Designed for surface mount technology. Replaces older through-hole or larger SMD solutions. Manufactured by Eaton Electronics Division under the Coiltronics brand heritage.

Arrays, Signal Transformers Replacement Considerations

CTX100-1-R offers similar inductance but different physical dimensions and current ratings. CTX100-2-R provides identical electrical characteristics but may differ in packaging or minor mechanical specs. Verify pinout and mounting hole patterns before substitution.
