Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via official documentation. Check for end-of-life notices as availability may be limited. Ensure storage conditions maintain integrity prior to soldering. Validate pinout compatibility with target PCB footprint.

Selection Notes

Select this component when high current capacity and compact size are required for EMI suppression. Consider the 6 A rating for power lines and the 50 V limit for low-voltage circuits. Evaluate thermal performance within the specified operating range. Compare attenuation characteristics against specific noise frequency profiles.

Part Context

This part belongs to the ACH series of three-terminal filters from TDK. These components are engineered for electromagnetic interference reduction in electronic circuits. The series offers various capacitance values to suit different filtering requirements while maintaining consistent physical dimensions and mounting styles.

Replacement Considerations

Refer to official TDK documentation for verified substitute part numbers. Cross-reference electrical parameters such as capacitance, current rating, and package dimensions. Ensure functional equivalence in noise suppression performance before substitution.
