Procurement Notes

This component is officially classified as obsolete and no longer manufactured by TDK Corporation. Procurement must rely on existing stock or authorized distributors holding legacy inventory. Verification of part authenticity and storage history is critical due to the end-of-life status. Buyers should confirm the specific revision and packaging condition before acquisition to ensure compatibility with current production requirements.

Selection Notes

Engineers replacing this obsolete part should evaluate the KYOCERA AVX W2F15C2238AT1A as a documented alternative. Selection criteria must match the original 0.022 µF capacitance, 25V rating, and 0805 footprint. Verify that the substitute maintains comparable insertion loss performance and current handling specifications to ensure circuit integrity without redesigning the filter network.

Part Context

The YFF-SC series represents TDK's line of ceramic feedthrough filters optimized for high-current applications. These components utilize a coaxial structure to minimize parasitic inductance, enhancing high-frequency noise attenuation. The YFF21SC1E223MT000N specifically targets scenarios requiring robust EMI filtering alongside significant DC load carrying capacity in space-constrained surface-mount designs.

Replacement Considerations

The KYOCERA AVX W2F15C2238AT1A is a confirmed public substitute for this obsolete part. Ensure mechanical fitment matches the 0805 package dimensions and verify electrical parameters align with system requirements.
