The explicit ‘AEC-Q200’ value of ‘YES’ further confirms its qualification for automotive use. A ‘Tolerance’ of ‘±20%’ on its capacitance value is typical for X7R dielectric capacitors, providing a practical range for many filtering and decoupling applications. The ‘L x W Size’ of ‘2.0mm x 1.25mm [EIA 0805]’ refers to its physical dimensions, corresponding to the widely used 0805 surface-mount package, which offers a balance between miniaturization and ease of handling. Its ‘Capacitance’ is ‘4.7nF’ (nanofarads), a common value for signal coupling, decoupling, and resonant circuits. The ‘T(Max.) / mm’ of ‘1’ indicates its maximum thickness, crucial for space-constrained designs. The ‘Temp. Chara.’ is ‘X7R’, a stable dielectric known for its capacitance change of ‘±15%’ over the full ‘Operating Temp. Range / °C’ of ‘-55 to 125’, making it suitable for a wide range of environmental conditions. The ‘Component Type’ is clearly defined as a ‘Ceramic Capacitor (MLCC)’, and its ‘Product Status’ is ‘Production’, ensuring ongoing availability. Finally, a ‘Rated Voltage [DC] / V’ of ‘100’ specifies the maximum DC voltage it can withstand continuously without breakdown, providing ample headroom for many automotive 12V and 24V systems.
