Key Specifications

• Apps. (Commercial Grade): This attribute signifies that the C3225X7R2A474K200AE capacitor is designed and tested for use in standard commercial electronic applications. It ensures reliability and performance suitable for a vast range of products, from consumer electronics to industrial control systems, where extreme conditions of automotive or military specifications are not required.
• Brand (TDK): TDK is a renowned Japanese multinational electronics company known for manufacturing high-quality electronic components. Specifying TDK as the brand assures buyers of the product’s origin from a reputable manufacturer with a long-standing history of innovation and reliability in the passive components market.
• Feature (MidSoft): The “MidSoft” feature indicates a specific dielectric material characteristic that provides a balance between mechanical robustness and electrical performance. This can be particularly beneficial in applications where some degree of mechanical stress or vibration might be present, helping to mitigate the risk of cracking or damage to the component.
• Tolerance (±10%): This specifies the permissible deviation of the actual capacitance value from its nominal value. A ±10% tolerance for the 470nF capacitance means the actual value will fall between 423nF and 517nF. This level of precision is common for general-purpose applications where exact capacitance is not critically sensitive but stability is still important.
• L x W Size (3.2mm x 2.5mm [EIA 1210]): This refers to the physical dimensions of the capacitor. The 3.2mm length by 2.5mm width corresponds to the industry-standard EIA 1210 package size. This standardized footprint is critical for PCB layout and automated assembly processes, ensuring compatibility with existing manufacturing equipment and design practices.
• Capacitance (470nF): The nominal capacitance value of 470 nanofarads (0.47 microfarads) indicates the component’s ability to store electrical charge. This value is suitable for a wide range of filtering, coupling, decoupling, and timing applications in various electronic circuits.
• T(Max.) / mm (2.3): This denotes the maximum thickness of the component, which is 2.3mm. Along with the length and width, this dimension is crucial for mechanical design and ensuring the component fits within specific height constraints on a printed circuit board, especially in compact or slim electronic devices.
• Temp. Chara. (X7R): X7R is a common dielectric material classification for ceramic capacitors, indicating its temperature characteristic. X7R capacitors are considered “temperature stable” and are suitable for a wide operating temperature range, exhibiting a predictable change in capacitance over temperature.
• Component Type (Ceramic Capacitor (MLCC)): This clearly identifies the product as a Multilayer Ceramic Capacitor. MLCCs are known for their small size, high capacitance values for their volume, low equivalent series resistance (ESR), and excellent high-frequency performance, making them ubiquitous in modern electronics.
• Product Status (Production): This indicates that the C3225X7R2A474K200AE is actively being manufactured and is readily available for purchase. This is important for designers and procurement teams, ensuring long-term supply and avoiding end-of-life concerns for new designs.
• Rated Voltage [DC] / V (100): The rated voltage of 100V DC specifies the maximum continuous DC voltage that can be applied across the capacitor without causing damage or degradation. This is a critical parameter for ensuring the capacitor’s safe operation and longevity within a circuit.
• Cap.Change or Temp.Coef. (±15%): For X7R dielectric, this specifies that the capacitance change over the full operating temperature range (-55°C to 125°C) will not exceed ±15% from its nominal value at 25°C. This characteristic is vital for applications requiring stable performance across varying environmental conditions.
• Operating Temp. Range / °C (-55 to 125): This defines the ambient temperature range within which the capacitor is designed to operate reliably. A wide range of -55°C to 125°C makes this component suitable for robust commercial and industrial applications that may experience significant temperature fluctuations.
