Key Specifications

This TDK CGA3E2X8R2A102K080AE MLCC boasts several critical specifications that define its performance and suitability for demanding applications. Its ‘Apps.’ attribute as ‘Automotive Grade’ signifies that it is engineered and tested to withstand the harsh conditions found in vehicles, including extreme temperatures, vibrations, and electrical transients. The ‘Brand’ is TDK, assuring a product from a reputable manufacturer known for its quality and innovation in passive components. A key ‘Feature’ is ‘AEC-Q200Mid150°CSoft’, indicating compliance with AEC-Q200 standards for automotive components, specifically designed for mid-range temperature applications up to 150°C, and likely incorporating soft termination technology to mitigate mechanical stress. The explicit ‘AEC-Q200’ attribute being ‘YES’ further confirms its automotive qualification. A ‘Tolerance’ of ‘±10%’ for capacitance ensures that the actual capacitance value remains within a tight range of the nominal 1nF, which is crucial for precise circuit timing and filtering. The ‘L x W Size’ of ‘1.6mm x 0.8mm [EIA 0603]’ denotes a compact surface-mount package, ideal for miniaturized electronic assemblies. The ‘Capacitance’ of ‘1nF’ (1000pF) is a common value suitable for various filtering, coupling, and decoupling applications. ‘T(Max.) / mm’ at ‘0.95’ specifies the maximum thickness of the component. The ‘Temp. Chara.’ of ‘X8R’ indicates a dielectric material that provides a capacitance change of ‘±15%’ over an ‘Operating Temp. Range / °C’ of ‘-55 to 150’, making it highly stable across a very broad temperature spectrum. Finally, a ‘Rated Voltage [DC] / V’ of ‘100’ defines the maximum DC voltage that can be continuously applied across the capacitor without breakdown, offering a good margin for many automotive power systems.
