Key Specifications

The attributes of the C2012X7R1A106K125AC are crucial for understanding its capabilities and suitability for specific designs. The Capacitance of 10μF indicates its energy storage capacity, a significant value for filtering and decoupling applications where substantial charge storage is required. The Rated Voltage [DC] / V of 10V specifies the maximum DC voltage that can be continuously applied across the capacitor without breakdown, making it suitable for low-voltage power rails and signal lines. Its Tolerance of ±10% defines the permissible variation from the nominal capacitance value, which is a standard commercial tolerance indicating good manufacturing precision. The L x W Size of 2.0mm x 1.25mm, corresponding to the EIA 0805 package, signifies its compact footprint, ideal for space-constrained PCB designs. The T(Max.) / mm of 1.45mm refers to the maximum thickness of the component, important for height-restricted assemblies. The Temp. Chara. of X7R is a critical material designation, indicating a dielectric that offers relatively stable capacitance over a wide temperature range. This is further quantified by Cap.Change or Temp.Coef. of ±15% over its full operating temperature range, meaning the capacitance will not deviate by more than 15% from its nominal value within that range. The Operating Temp. Range / °C of -55 to 125°C highlights its robust performance across extreme environmental conditions, suitable for a broad spectrum of commercial and industrial applications. Lastly, its Product Status as ‘Production’ confirms that this component is actively manufactured and readily available for new designs and mass production.
