CA2666Z7U473M500R – SAMWHA

The CA2666Z7U473M500R designates a SAMWHA Electronics multilayer ceramic capacitor (MLCC) supplied on a 5000-piece reel for automated assembly. This component features a rated voltage of 50V DC, suitable for decoupling and bypass applications in low-voltage circuits. The capacitance value is 0.047µF (47nF), derived from the “473” marking, where “47” represents the significant digits and “3” indicates a multiplier of 10^3 picofarads. The “Z7U” dielectric classification signifies a Class II ceramic capacitor, exhibiting a capacitance variation of +22%/-56% over the operating temperature range. The “M” tolerance code indicates a capacitance tolerance of ±20%. The physical dimensions are encoded in the “2666” portion of the part number, but require further manufacturer documentation to decode the exact length and width in millimeters. The “R” suffix denotes reel packaging.
