Procurement Notes

Verify the specific suffix (TL vs TD01) against your Bill of Materials, as packaging quantities may differ. Confirm RoHS compliance status and lead-free certification with the supplier prior to ordering. Ensure the operating temperature range meets your system requirements, noting the minimum operating temperature specification. Cross-reference the manufacturer part number with official TDK documentation to avoid counterfeit components.

Selection Notes

Select this component when high attenuation in a small footprint is required for signal lines carrying up to 300 mA. The magnetic shielding makes it suitable for dense PCB layouts where crosstalk must be minimized. Compare its cutoff frequency and impedance characteristics against other ACF series variants to ensure compatibility with your specific noise profile and power constraints.

Part Context

This component belongs to the TDK ACF series of signal line filters. The series is characterized by its use of ferrite materials and T-type circuit configurations to achieve effective electromagnetic interference suppression. These filters are widely used in applications requiring robust noise reduction within strict size limitations, such as consumer electronics and automotive systems.

Replacement Considerations

Check for direct substitutes within the ACF series with similar current ratings and dimensions. Verify that any replacement maintains the same third-order low-pass characteristic and magnetic shielding properties. Ensure the alternative component meets the same voltage and temperature specifications.
