Key Specifications

The CAA572C0G2J204G640LJ boasts several key specifications that underscore its suitability for advanced applications. The “Apps.” attribute, explicitly stating “Automotive Grade,” signifies that this capacitor is engineered and tested to meet the rigorous demands of the automotive industry, including harsh environmental conditions and long operational lifespans. The “Brand” is TDK, a testament to its quality and manufacturing excellence. Its “Feature” set, “AEC-Q200MidMEGA ILowR,” highlights its compliance with AEC-Q200 standards for automotive components, its mid-range mega-ohm insulation resistance, and critically, its low equivalent series resistance (ESR), which is vital for efficient power delivery and reduced heat generation. The explicit “AEC-Q200” “YES” confirms its qualification for automotive applications. A tight “Tolerance” of “±2%” indicates high precision in its capacitance value, crucial for sensitive timing and filtering circuits. The “L x W Size” of “5.7mm x 5.0mm [EIA 2220]” specifies its physical dimensions, adhering to the industry-standard EIA 2220 package, which is a relatively large surface-mount footprint suitable for higher power or voltage applications. With a “Capacitance” of “200nF,” it offers a substantial charge storage capability. The maximum thickness, “T(Max.) / mm” of “6.9mm,” provides important physical clearance information for PCB design. The “Temp. Chara.” of “C0G” is a highly stable temperature characteristic, meaning its capacitance changes very little over a wide temperature range, as further detailed by “Cap.Change or Temp.Coef.” of “0±30ppm/°C,” indicating a negligible change of 0 parts per million per degree Celsius with a tolerance of ±30ppm/°C. This stability is critical for precision applications. As a “Component Type” Ceramic Capacitor (MLCC), it leverages multi-layer ceramic technology for compactness and reliability. Its “Product Status” is “Production,” ensuring ongoing availability. A high “Rated Voltage [DC] / V” of “630V” allows it to be used in circuits with significant voltage levels. Finally, an extensive “Operating Temp. Range / °C” of “-55 to 125” confirms its ability to perform reliably in extreme hot and cold environments typical of automotive under-hood or industrial settings.
