Procurement Notes

This component is classified as End-of-Life by the manufacturer. Availability is limited to existing stock or obsolete channels. Verify RoHS compliance status and lead times carefully when sourcing from third-party distributors. Ensure compatibility with current design requirements before procurement due to discontinuation status.

Selection Notes

Select this part for applications requiring compact EMI filtering on signal lines with low current demands. The 1812 footprint suits space-constrained designs. Consider the 300 mA current limit and 50 V rating during circuit design. Evaluate alternative components if long-term supply stability is critical, given the discontinued status.

Part Context

The ACF451832 series consists of signal line EMI filters manufactured by TDK Corporation. These components are engineered for noise suppression in high-speed digital circuits. The specific model utilizes a T-type LC configuration to achieve targeted attenuation characteristics while maintaining signal integrity in portable electronic devices.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the End-of-Life status, direct replacements may require functional equivalence analysis. Consult TDK technical support or authorized distributors for validated alternatives compatible with the 1812 package and specified electrical parameters.
