Key Specifications

• Apps. (Automotive Grade): This attribute signifies that the capacitor is specifically designed and qualified for use in automotive electronics. Components designated as ‘Automotive Grade’ undergo rigorous testing to ensure reliability and performance under the harsh conditions typically found in vehicles, such as extreme temperatures, vibrations, and electrical transients. This is crucial for safety-critical systems like ADAS, engine control units, and infotainment.
• Brand (TDK): TDK is a renowned Japanese multinational electronics company known for its expertise in magnetic and electronic components. Choosing a TDK component ensures high manufacturing standards, consistent quality, and reliable performance, backed by extensive research and development.
• Feature (AEC-Q200Soft): The ‘AEC-Q200Soft’ feature indicates that this capacitor not only meets the AEC-Q200 standard but also incorporates soft termination technology. Soft termination helps to mitigate the risk of cracking due to thermal expansion/contraction or board bending, enhancing the component’s mechanical robustness and long-term reliability in demanding environments.
• AEC-Q200 (YES): AEC-Q200 is a fundamental stress test qualification for passive components used in automotive applications. A ‘YES’ confirms that the CGA3E2X7R1H472K080AE has successfully passed these rigorous tests, ensuring its suitability for the automotive industry’s stringent reliability requirements.
• Tolerance (±10%): This specifies the permissible deviation of the actual capacitance value from its nominal value. A ±10% tolerance is common for X7R dielectric capacitors, indicating a reasonable level of precision suitable for many filtering, coupling, and bypass applications where exact capacitance is not hyper-critical but stability is important.
• L x W Size (1.6mm x 0.8mm [EIA 0603]): This denotes the physical dimensions of the capacitor in a surface-mount device (SMD) package. The 0603 EIA standard size is widely adopted, offering a balance between miniaturization and ease of handling during automated assembly processes, making it suitable for compact PCB designs.
• Capacitance (4.7nF): The nominal capacitance value of 4.7 nanofarads (nF) indicates the component’s ability to store electrical charge. This value is commonly used in various circuit functions, including high-frequency decoupling, signal coupling, and timing circuits.
• T(Max.) / mm (0.95): This refers to the maximum thickness of the component, which is 0.95mm. This dimension is critical for PCB layout and ensuring adequate clearance in compact electronic assemblies.
• Temp. Chara. (X7R): X7R is a common dielectric material for ceramic capacitors, known for its stable performance across a wide temperature range. It is considered a ‘temperature-stable’ dielectric, suitable for applications where capacitance variations with temperature need to be minimized, though it is not as stable as C0G/NP0.
• Component Type (Ceramic Capacitor (MLCC)): This identifies the fundamental type of component. MLCCs (Multi-Layer Ceramic Capacitors) are characterized by their compact size, high reliability, and excellent frequency response, making them ubiquitous in modern electronics.
• Product Status (Production): ‘Production’ status indicates that the component is actively being manufactured and is generally available for purchase in volume, ensuring long-term supply for product designs.
• Rated Voltage [DC] / V (50): This is the maximum DC voltage that can be continuously applied across the capacitor without causing damage or degradation. A 50V rating provides a sufficient margin for many automotive and industrial control applications.
• Cap.Change or Temp.Coef. (±15%): For X7R dielectrics, this specifies the maximum percentage change in capacitance over the full operating temperature range. A ±15% change is typical for X7R, making it suitable for applications where moderate capacitance stability is acceptable.
• Operating Temp. Range / °C (-55 to 125): This defines the temperature range within which the capacitor is designed to operate reliably and meet its specified electrical characteristics. A wide range like -55°C to 125°C is essential for automotive applications, which often experience extreme thermal conditions.
