Key Specifications

The attributes of the C2012X7R1A106K125AE are critical for understanding its suitability for various designs:

• Apps. (Commercial Grade): This designation indicates that the capacitor is engineered to meet the robust requirements of general commercial electronics, ensuring reliable performance in a broad spectrum of non-automotive or non-critical industrial applications.
• Brand (TDK): TDK is a renowned Japanese multinational electronics company known for its high-quality passive components, ensuring that this capacitor meets stringent manufacturing and performance standards.
• Feature (Soft): The “Soft” feature often refers to the termination type, which provides enhanced mechanical stress resistance. This can be crucial in applications where board flexure or thermal cycling might otherwise lead to cracking of the ceramic body, improving the component’s long-term reliability.
• Tolerance (±10%): A capacitance tolerance of ±10% means the actual capacitance value will be within 10% of the nominal 10μF. This level of precision is suitable for many filtering, decoupling, and general-purpose applications where exact capacitance is not critically sensitive.
• L x W Size (2.0mm x 1.25mm [EIA 0805]): This standard surface-mount package size, commonly known as 0805, indicates a compact footprint ideal for miniaturized electronic assemblies. The dimensions allow for efficient board space utilization.
• Capacitance (10μF): With a nominal capacitance of 10 microfarads, this component is well-suited for bulk decoupling, low-frequency filtering, and energy storage tasks in power management circuits.
• T(Max.) / mm (1.5): This specifies the maximum thickness of the component as 1.5mm. This dimension is important for mechanical design and clearance considerations in compact enclosures.
• Temp. Chara. (X7R): X7R is a common dielectric material for ceramic capacitors, known for its relatively stable capacitance over a wide temperature range. It is considered a “temperature-stable” dielectric, suitable for applications requiring predictable performance across varying environmental conditions.
• Component Type (Ceramic Capacitor (MLCC)): As a Multilayer Ceramic Capacitor, it offers high volumetric efficiency, low equivalent series resistance (ESR), and excellent high-frequency performance, making it a versatile choice for modern electronics.
• Product Status (Production): This indicates that the component is actively being manufactured and is readily available for new designs and mass production, ensuring long-term supply.
• Rated Voltage [DC] / V (10): The capacitor is rated for a maximum DC voltage of 10V. This is a critical parameter that must not be exceeded to prevent dielectric breakdown and component failure.
• Cap.Change or Temp.Coef. (±15%): For X7R dielectrics, the capacitance change over the full operating temperature range (-55°C to 125°C) is specified as ±15%. This provides designers with an understanding of how much the capacitance can drift with temperature variations.
• Operating Temp. Range / °C (-55 to 125): This wide operating temperature range signifies the capacitor’s robustness and suitability for use in harsh environments, from extreme cold to high heat, without significant degradation in performance.

Features and Benefits

• High Capacitance in a Compact Size: The 10μF capacitance in an 0805 package (2.0mm x 1.25mm) allows for significant space savings on PCBs, crucial for miniaturized electronic devices.
• Excellent Temperature Stability (X7R Dielectric): The X7R dielectric ensures that the capacitance remains relatively stable (±15%) across a broad operating temperature range of -55°C to 125°C, providing reliable performance in varying thermal conditions.
• Enhanced Mechanical Reliability (Soft Termination): The “Soft” feature helps mitigate the risk of cracking due to board flexure or thermal shock, extending the operational lifespan of the component in demanding applications.
• Trusted TDK Quality: Manufactured by TDK, a leading name in passive components, this MLCC guarantees high quality, consistent performance, and adherence to industry standards.
• Versatile Commercial Grade Application: Designed for commercial-grade use, it offers a cost-effective yet reliable solution for a wide array of electronic products, from consumer electronics to industrial control systems.
