Key Specifications

• Apps. (Commercial Grade): This designation indicates that the C2012X7T2E473K125AA capacitor is engineered for use in general electronic products where standard reliability and performance are required, as opposed to specialized automotive or industrial applications that might demand higher robustness.
• Brand (TDK): TDK is a renowned Japanese multinational electronics company known for its high-quality electronic components, including a comprehensive range of capacitors. Choosing a TDK component ensures adherence to global manufacturing standards and reliable performance.
• Feature (Mid): The ‘Mid’ feature likely refers to its general-purpose characteristics, positioning it as a versatile component suitable for a broad spectrum of applications without being overly specialized for extreme high-frequency or high-power scenarios.
• Tolerance (±10%): This specification indicates that the actual capacitance value of the component will be within ±10% of its nominal 47nF value. A 10% tolerance is common for many general-purpose applications, providing a good balance between precision and cost-effectiveness.
• L x W Size (2.0mm x 1.25mm [EIA 0805]): This defines the physical dimensions of the capacitor, corresponding to the EIA (Electronic Industries Alliance) 0805 standard package size. This compact footprint is widely used in surface-mount technology (SMT) designs, enabling miniaturization of electronic devices.
• Capacitance (47nF): The nominal capacitance value of 47 nanofarads (nF) determines the amount of electrical charge the capacitor can store. This value is suitable for various filtering, coupling, and bypass applications in many electronic circuits.
• T(Max.) / mm (1.45): This indicates the maximum thickness of the component, which is 1.45mm. This dimension is crucial for PCB layout and ensuring the component fits within specific height constraints in compact designs.
• Temp. Chara. (X7T): The X7T temperature characteristic specifies the capacitor’s performance over a defined temperature range. For X7T, the capacitance change is within +22% to -33% over an operating temperature range of -55°C to +125°C, making it suitable for applications requiring stable performance across a wide thermal spectrum.
• Component Type (Ceramic Capacitor (MLCC)): This confirms it is a Multilayer Ceramic Capacitor, known for its excellent frequency response, low ESR (Equivalent Series Resistance), and compact size, making it ideal for high-density circuit boards.
• Product Status (Production): This signifies that the component is actively being manufactured and is readily available for purchase, ensuring long-term supply for new and existing designs.
• Rated Voltage [DC] / V (250): The capacitor is rated for a maximum DC voltage of 250V. This means it can safely operate in circuits where the DC voltage across its terminals does not exceed 250 volts, providing a robust margin for many common power supply and signal processing applications.
• Cap.Change or Temp.Coef. (+22,-33%): This reiterates the capacitance change percentage over the specified operating temperature range, directly linked to the X7T temperature characteristic. It quantifies the maximum deviation from the nominal capacitance due to temperature fluctuations.
• Operating Temp. Range / °C (-55 to 125): This broad operating temperature range from -55°C to +125°C highlights the capacitor’s robustness and suitability for use in demanding environments, from extreme cold to high heat, without significant degradation in performance.
