Procurement Notes
Verify the exact datasheet version from Central Technologies before ordering. Confirm that the 80 mH inductance and 4.5 Ohm DCR meet your circuit requirements. Ensure the through-hole package dimensions align with your PCB footprint. Check for alternative part numbers if supply constraints exist.
Selection Notes
Select this component when high current handling up to 1200A bipolar is required. Consider the 20kHz-200kHz frequency range for appropriate switching applications. The metal alloy core offers distinct performance characteristics compared to ferrite alternatives. Verify thermal limits against your specific operating environment.
Part Context
This part belongs to the CTCSF series of current sense transformers and inductors from Central Technologies. The series provides various options for current monitoring in industrial and commercial power applications. Specific model variants differ in electrical ratings and physical dimensions.
Replacement Considerations
Check manufacturer documentation for direct substitutes. Alternative components must match the 80 mH inductance and 4.5 Ohm DCR specifications. Verify compatibility with the 20kHz-200kHz operating frequency range.
