Key Specifications

The attributes of the CGJ4J1X7R0J106K125AC provide a comprehensive understanding of its capabilities and suitability for various applications:

• Applications (High Reliability Grade): This designation indicates that the capacitor is engineered for use in critical systems where failure is unacceptable, such as automotive, industrial control, or medical devices, demanding superior performance and longevity.
• Brand (TDK): TDK is a renowned Japanese multinational electronics company known for its high-quality electronic components, ensuring reliability and adherence to stringent manufacturing standards.
• Feature (AEC-Q200 General) & AEC-Q200 (YES): AEC-Q200 certification signifies that the component meets the Automotive Electronics Council’s rigorous stress test qualification for passive components, making it suitable for automotive applications and other environments requiring high robustness.
• Tolerance (±10%): This indicates the permissible deviation of the actual capacitance value from the nominal 10μF. A ±10% tolerance is standard for many general-purpose and even some precision applications, ensuring consistent circuit performance.
• L x W Size (2.0mm x 1.25mm [EIA 0805]): This specifies the physical dimensions of the capacitor. The EIA 0805 standard size is a widely adopted surface-mount package, offering a balance between component size and ease of handling during assembly.
• Capacitance (10μF): This is the primary electrical characteristic, indicating the component’s ability to store charge. A 10μF capacitance is substantial for an 0805 package, making it suitable for decoupling, filtering, and energy storage in power supply lines.
• T(Max.) / mm (1.45): This refers to the maximum thickness of the component, which is crucial for PCB layout and ensuring proper clearance in compact designs.
• Temp. Chara. (X7R) & Cap.Change or Temp.Coef. (±15%): X7R is a common dielectric material for ceramic capacitors, known for its stable performance across a wide temperature range. The ±15% capacitance change over the operating temperature range (-55 to 125°C) indicates its suitability for applications where temperature stability is important, though not as precise as C0G/NP0 dielectrics.
• Component Type (Ceramic Capacitor (MLCC)): Confirms its classification as a Multilayer Ceramic Capacitor, known for its compact size, high frequency performance, and reliability.
• Product Status (Obsolete): While the product is marked as obsolete, it may still be available for purchase to support existing designs or for specific replacement needs, often through specialized distributors.
• Rated Voltage [DC] / V (6.3): This is the maximum DC voltage that can be continuously applied across the capacitor without causing damage. A 6.3V rating is common for low-voltage digital and analog circuits.
• Operating Temp. Range / °C (-55 to 125): This wide temperature range highlights the capacitor’s robustness, allowing it to function reliably in extreme cold and hot environments, a key requirement for high-reliability and automotive applications.
