Key Specifications

The CKG57KX7T2J334M335JJ boasts several key specifications that underscore its suitability for demanding applications. Its ‘Apps.’ attribute as ‘Automotive Grade’ signifies that it is specifically engineered and tested to withstand the harsh environments typical of automotive systems, including extreme temperatures, vibrations, and electrical transients. The ‘Brand’ TDK assures users of its origin from a reputable manufacturer known for quality and innovation. A crucial ‘Feature’ is ‘AEC-Q200MidMega’, indicating compliance with the Automotive Electronics Council’s AEC-Q200 standard, a benchmark for passive components in automotive applications, ensuring high levels of reliability and qualification. The explicit ‘AEC-Q200’ value of ‘YES’ further confirms this compliance. A ‘Tolerance’ of ‘±20%’ specifies the permissible deviation from its nominal capacitance value, which is 330nF, indicating a standard level of precision for many automotive power and signal conditioning applications. The ‘L x W Size’ of ‘5.7mm x 5.0mm [EIA 2220]’ refers to its physical dimensions, aligning with the EIA 2220 standard package size, which is a relatively large form factor often chosen for higher capacitance values or voltage ratings. The ‘T(Max.) / mm’ of ‘3.5’ denotes its maximum thickness. Its ‘Temp. Chara.’ is ‘X7T’, a temperature characteristic that defines its capacitance change over a specified temperature range, in this case, a ‘Cap.Change or Temp.Coef.’ of ‘+22,-33%’ over an ‘Operating Temp. Range / °C’ of ‘-55 to 125’, highlighting its stable performance across a broad temperature spectrum. The ‘Component Type’ is clearly identified as a ‘Ceramic Capacitor (MLCC)’, and its ‘Product Status’ as ‘Production’ confirms its active manufacturing and availability. Finally, a ‘Rated Voltage [DC] / V’ of ‘630’ indicates the maximum DC voltage it can continuously withstand without breakdown, making it suitable for higher voltage automotive circuits.
