CK45-R3DD472K-NRA from TDK Corporation is a ceramic capacitor intended for general electronic circuit use where stable passive performance, compact form factor, and broad application flexibility are important. Ceramic capacitors in this class are commonly selected for filtering, coupling, bypass, decoupling, and noise-suppression functions across consumer, industrial, and embedded designs. For design teams, this part may be relevant when maintaining existing platforms, evaluating second-source options, or supporting repair and service requirements tied to TDK passive components. Because the exact electrical specifications, lifecycle position, and environmental declarations were not provided here, engineers and buyers should confirm capacitance characteristics, voltage rating, dielectric type, packaging, and qualification status directly from the latest TDK datasheet and authorized channel data. Lifecycle status is currently listed as unknown, so supply continuity should be reviewed before release to production. RoHS compliance information is not available in the provided data and should be verified with manufacturer documentation before procurement.
