Procurement Notes

Verify the specific revision status and RoHS compliance documentation directly with TDK Corporation or authorized distributors before procurement. Confirm that the 0805 footprint matches the target PCB design constraints. Ensure the 10V rating and 100mA current handling are sufficient for the intended circuit application. Check for any obsolete status notifications or lifecycle changes associated with this part number.

Selection Notes

Select this component when third-order attenuation is required for data lines in compact mobile form factors. The 0805 size offers a balance between filtering performance and board space efficiency. Consider the 10V rating and 100mA limit against the system's electrical requirements. Verify compatibility with the target operating temperature range of -40°C to +85°C for the specific environment.

Part Context

This part belongs to TDK's MEM series of EMI/RFI filters, which are engineered for noise suppression in consumer electronics. The MEM series typically utilizes multi-layer ceramic or chip inductor technologies to provide compact solutions for high-frequency interference. This specific model represents a standard solution for protecting sensitive data pathways in portable devices where space is limited.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Engineers should consult TDK Corporation's official substitution guide or contact technical support for verified alternatives. Cross-referencing with other manufacturers requires careful validation of impedance characteristics and physical dimensions.
