Key Specifications

This TDK CGA4J3X7R1C475K125AE MLCC boasts several critical specifications that define its performance and suitability for specific applications:

• Applications: Automotive Grade – This designation signifies that the capacitor is specifically designed and tested to meet the rigorous demands of automotive electronics, ensuring reliable operation in harsh environments characterized by extreme temperatures, vibrations, and electrical stresses.
• Brand: TDK – TDK is a renowned Japanese multinational electronics company known for its high-quality passive components, magnetic products, and other electronic devices. Their brand signifies reliability and technological advancement.
• Feature: AEC-Q200 Soft Termination – The “Soft Termination” feature is a critical enhancement for automotive applications. It incorporates a flexible conductive layer between the ceramic body and the external electrodes, which helps to absorb mechanical stresses and prevent cracking due to thermal cycling or board flexure, significantly improving reliability.
• AEC-Q200: YES – This confirms that the component is qualified to the Automotive Electronics Council’s AEC-Q200 standard, a widely recognized benchmark for passive electronic components used in automotive applications. This qualification ensures high levels of reliability and quality.
• Tolerance: ±10% – This indicates that the actual capacitance value of the component will be within ±10% of its nominal 4.7μF value. This tolerance level is common for general-purpose and automotive applications, providing sufficient precision for most circuit designs.
• L x W Size: 2.0mm x 1.25mm [EIA 0805] – This specifies the physical dimensions of the capacitor, corresponding to the industry-standard 0805 package size. This compact footprint is highly desirable for miniaturized electronic assemblies, allowing for higher component density on printed circuit boards.
• Capacitance: 4.7μF – This is the nominal capacitance value, indicating the component’s ability to store electrical charge. A 4.7μF capacitance is suitable for a wide range of filtering, decoupling, and energy storage applications.
• T(Max.) / mm: 1.5 – This refers to the maximum thickness of the component, which is 1.5mm. This dimension is crucial for mechanical design and ensuring proper fit within constrained spaces.
• Temperature Characteristic: X7R – X7R is a common dielectric material for ceramic capacitors, known for its stable performance over a wide temperature range. It guarantees a capacitance change of no more than ±15% from its nominal value across its operating temperature range.
• Component Type: Ceramic Capacitor (MLCC) – This identifies the fundamental type of component. MLCCs are highly versatile, offering high capacitance in small packages, excellent frequency response, and high reliability.
• Product Status: Production – This indicates that the component is actively being manufactured and is readily available for purchase and integration into new designs.
• Rated Voltage [DC] / V: 16 – This is the maximum DC voltage that can be continuously applied across the capacitor without causing damage or premature failure. A 16V rating is common for many low-voltage automotive and general electronic systems.
• Cap. Change or Temp. Coef.: ±15% – This reiterates the capacitance stability over temperature, specifically for the X7R dielectric. It means the capacitance will not deviate by more than ±15% from its 25°C value over the full operating temperature range.
• Operating Temp. Range / °C: -55 to 125 – This specifies the extreme temperatures at which the capacitor is designed to operate reliably. The broad range from -55°C to 125°C is characteristic of automotive-grade components, ensuring functionality in diverse climatic conditions.
