Key Specifications

• Applications (High Reliability Grade): This attribute signifies that the CGJ3E2X7R1H473K080AA is engineered for environments where failure is not an option. Components designated as ‘High Reliability Grade’ undergo more stringent testing and quality control processes to ensure consistent performance and longevity in critical systems, such as automotive, industrial, and medical electronics.
• Brand (TDK): TDK is a renowned Japanese multinational electronics company known for its high-quality passive components, including capacitors, inductors, and ferrites. Their brand presence assures engineers of a product built to exacting standards with a long history of innovation and reliability in the electronics industry.
• Feature (AEC-Q200 General): The ‘AEC-Q200 General’ feature indicates that this capacitor meets the Automotive Electronics Council’s AEC-Q200 standard for passive components. This certification is crucial for components used in automotive applications, ensuring they can withstand the harsh environmental and operational conditions typical of vehicles, including extreme temperatures, vibrations, and electrical stresses.
• AEC-Q200 (YES): Explicitly stating ‘YES’ for AEC-Q200 reinforces its suitability for automotive and other demanding applications where robust performance under stress is paramount. This compliance is a key differentiator for designers seeking components that meet rigorous industry standards.
• Tolerance (±10%): A capacitance tolerance of ±10% means that the actual capacitance value of the component will fall within 10% above or below its nominal value of 47nF. This level of precision is suitable for many general-purpose and even some semi-critical applications where exact capacitance is important but not ultra-critical, allowing for some variation in circuit performance.
• L x W Size (1.6mm x 0.8mm [EIA 0603]): This specifies the physical dimensions of the capacitor, corresponding to the EIA 0603 standard package size. This miniature footprint is highly desirable in modern electronics, enabling compact circuit board designs and higher component density, which is essential for portable devices and space-constrained applications.
• Capacitance (47nF): The nominal capacitance value of 47 nanofarads (nF) indicates the amount of electrical charge the capacitor can store. This value is commonly used for decoupling, filtering, and timing applications in various digital and analog circuits, providing sufficient charge storage for moderate frequency operations.
• T(Max.) / mm (0.9): This refers to the maximum thickness of the component, which is 0.9mm. This dimension is critical for mechanical design and assembly, especially in thin electronic devices where vertical clearance is limited.
• Temp. Chara. (X7R): The X7R temperature characteristic is a common dielectric material for ceramic capacitors. It indicates that the capacitance change over the operating temperature range of -55°C to +125°C will be within ±15%. This makes X7R capacitors suitable for a broad range of industrial and automotive applications where stable performance across varying temperatures is required.
• Component Type (Ceramic Capacitor (MLCC)): This clearly identifies the product as a Multilayer Ceramic Capacitor, highlighting its construction and material, which are key to its electrical properties and compact size.
• Product Status (Obsolete): The ‘Obsolete’ status indicates that this specific part is no longer actively manufactured by TDK. While it may still be available through distributors from existing stock, it is advisable for new designs to consider alternative, currently active components.
• Rated Voltage [DC] / V (50): The rated voltage of 50V DC is the maximum continuous DC voltage that can be applied across the capacitor without risk of dielectric breakdown. This rating ensures the capacitor can safely operate in circuits with supply voltages up to 50V, providing a margin of safety for typical 5V, 12V, or 24V systems.
• Cap.Change or Temp.Coef. (±15%): This reiterates the capacitance change over temperature, specifically for the X7R dielectric. It means that from -55°C to +125°C, the capacitance will not deviate by more than ±15% from its value at room temperature, ensuring relatively stable performance across a wide thermal range.
• Operating Temp. Range / °C (-55 to 125): This broad operating temperature range signifies the capacitor’s ability to function reliably in extreme hot and cold environments. This makes it suitable for demanding applications such as automotive under-the-hood electronics, industrial control systems, and outdoor equipment.
