Procurement Notes

Verify the part status carefully as multiple sources indicate this specific model may be obsolete or discontinued. Confirm availability through authorized distributors or official TDK channels before finalizing procurement plans. Ensure the replacement strategy accounts for potential supply chain constraints associated with end-of-life components.

Selection Notes

Select this component when a low-profile feed-through solution is required for EMI suppression in 25V applications. Consider the specific tolerance requirements (-50% to +20%) and the 500mA current limit during circuit design. Evaluate alternative models if higher capacitance stability or different package sizes are necessary for the target application.

Part Context

This component belongs to the YFF-SC series of feed-through capacitors manufactured by TDK Corporation. These devices are engineered to combine the functions of a capacitor and an inductor into a single surface-mount package, providing effective noise attenuation without requiring additional discrete components.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the potentially obsolete status of this specific model, engineers should consult TDK's official obsolescence notices or contact authorized distributors for recommended equivalent parts that meet the same electrical and mechanical specifications.
