Components designated as ‘Automotive Grade’ undergo rigorous testing to ensure reliability, durability, and performance under the extreme conditions often found in vehicles, such as wide temperature variations, vibrations, and electrical transients.
• Brand (TDK): TDK is a renowned Japanese multinational electronics company known for its high-quality electronic components, including capacitors, inductors, and magnetic products. Their brand signifies a commitment to innovation, precision engineering, and reliability in the electronics industry.
• Feature (AEC-Q200 150°C Glue): This highlights key characteristics. ‘AEC-Q200’ indicates compliance with the Automotive Electronics Council’s standard for passive components, ensuring suitability for automotive use. The ‘150°C’ specifies its maximum operating temperature, while ‘Glue’ suggests a specific mounting or bonding characteristic, likely enhancing its mechanical stability in harsh environments.
• AEC-Q200 (YES): Explicitly confirms that the component meets the AEC-Q200 standard, which is a critical qualification for any electronic component intended for automotive applications. This standard defines the stress test qualification requirements for passive components.
• Tolerance (±10%): This specifies the permissible deviation of the actual capacitance value from its nominal value. A ±10% tolerance means the capacitance can vary by up to 10% higher or lower than 47nF, which is a common and acceptable range for many general and automotive applications, balancing precision with cost-effectiveness.
• L x W Size (1.6mm x 0.8mm [EIA 0603]): This denotes the physical dimensions of the surface-mount device (SMD) capacitor. The 1.6mm length and 0.8mm width correspond to the industry-standard EIA 0603 package size. This compact footprint is crucial for miniaturization in modern electronic circuits, allowing for high-density board designs.
• Capacitance (47nF): The nominal capacitance value of 47 nanofarads (nF), or 0.047 microfarads (µF), indicates the component’s ability to store electrical charge. This value is suitable for a wide range of filtering, coupling, and decoupling applications in various electronic circuits.
• T(Max.) / mm (0.95): This refers to the maximum thickness of the component, which is 0.95 millimeters. This dimension is important for mechanical design, ensuring proper fit and clearance on printed circuit boards, especially in space-constrained applications.
• Temp. Chara. (X8R): X8R is a specific dielectric material classification defined by EIA standards. X8R capacitors are known for their stable capacitance change over a wide temperature range. Specifically, an X8R dielectric ensures that the capacitance changes by no more than ±15% from its nominal value over an operating temperature range of -55°C to +150°C, making it highly suitable for extreme temperature environments.
• Component Type (Ceramic Capacitor (MLCC)): This identifies the fundamental type of component. MLCCs (Multi-Layer Ceramic Capacitors) are widely used due to their small size, high capacitance values for their footprint, and excellent high-frequency performance.
• Product Status (Production): This indicates that the CGA3E2X8R1H473K080AD is actively being manufactured and is available for purchase in volume. This ensures long-term supply and support for new and existing designs.
• Rated Voltage [DC] / V (50): This is the maximum DC voltage that can be continuously applied across the capacitor without causing damage or premature failure. A 50V rating provides a sufficient margin for many automotive and industrial applications, ensuring reliable operation under typical voltage fluctuations.
• Cap.Change or Temp.Coef. (±15%): This reiterates the capacitance change over the specified temperature range, directly correlating with the X8R dielectric characteristic. It means the capacitance will remain within ±15% of its initial value from -55°C to +150°C.
• Operating Temp. Range / °C (-55 to 150): This specifies the full range of ambient temperatures within which the capacitor is designed to operate reliably. The broad range from -55°C to +150°C underscores its suitability for harsh automotive environments, including engine compartments and other areas exposed to extreme heat and cold.
