Procurement Notes
Verify the specific suffix codes against official KEMET documentation to confirm exact electrical tolerances and termination specifications. Ensure that the selected variant meets the required AEC-Q200 qualification if automotive compliance is mandatory. Cross-reference the datasheet revision date to validate current manufacturing status and availability constraints before finalizing procurement orders.
Selection Notes
Select this component when high inductance is required for low-frequency noise attenuation in through-hole designs. Evaluate the 200 mA current limit against peak load requirements to prevent saturation. Consider the 6.5 ohm DC resistance impact on voltage drop. Verify that the 125 V AC rating aligns with the system's line voltage specifications and operating environment.
Part Context
This component belongs to the SU7VC series of common mode chokes manufactured by KEMET. The series is engineered for robust EMI suppression in demanding environments. These filters are commonly integrated into power input stages to mitigate conducted emissions. The design emphasizes durability and consistent performance across wide temperature ranges.
Replacement Considerations
Consult official KEMET substitution guides for verified equivalents. Generic replacements may not match the precise inductance tolerance or thermal characteristics. Ensure any substitute maintains the same form factor and electrical ratings to preserve circuit functionality.
