Key Specifications

The CGA4J1X8L1A106K125AC boasts several critical specifications that define its functionality and suitability for specific applications. Its ‘Apps.’ attribute as ‘Automotive Grade’ signifies compliance with rigorous automotive industry standards, making it ideal for use in vehicles where reliability is paramount. The ‘Brand’ is TDK, a testament to its quality and engineering excellence. A key ‘Feature’ is ‘AEC-Q200 150°C’, indicating that it is qualified to the Automotive Electronics Council’s AEC-Q200 standard and can operate reliably at temperatures up to 150°C, a crucial factor for under-the-hood applications. The explicit ‘AEC-Q200’ attribute being ‘YES’ further confirms this qualification. The ‘Tolerance’ of ‘±10%’ for its capacitance value means that the actual capacitance will be within 10% of the nominal value, which is a standard and acceptable range for many circuit designs. The ‘L x W Size’ is ‘2.0mm x 1.25mm [EIA 0805]’, corresponding to the widely used 0805 imperial case size, offering a balance between miniaturization and ease of handling/soldering. With a ‘Capacitance’ of ’10μF’, this capacitor provides substantial energy storage for filtering and decoupling applications. The ‘T(Max.) / mm’ of ‘1.5’ specifies its maximum thickness, important for space-constrained designs. The ‘Temp. Chara.’ is ‘X8L’, a dielectric material known for its stable capacitance over a wide temperature range, specifically from -55°C to +150°C, with a ‘Cap.Change or Temp.Coef.’ of ‘+15,-40%’. This indicates that the capacitance will not vary by more than +15% or -40% across its full operating temperature range. The ‘Component Type’ is clearly a ‘Ceramic Capacitor (MLCC)’, highlighting its construction and dielectric properties. Its ‘Product Status’ is ‘Production’, ensuring long-term availability. The ‘Rated Voltage [DC] / V’ is ’10’, meaning it can safely operate in circuits with a maximum DC voltage of 10 volts. Finally, the ‘Operating Temp. Range / °C’ from ‘-55 to 150’ confirms its robust performance across extreme thermal conditions.
