Key Specifications

• Applications (Automotive Grade): This attribute signifies that the capacitor is specifically designed and tested to meet the stringent requirements of automotive electronics. Components designated as ‘Automotive Grade’ are built to withstand harsh environmental conditions, including wide temperature variations, vibrations, and electrical stresses, ensuring reliable operation in critical vehicle systems.
• Brand (TDK): TDK is a renowned Japanese multinational electronics company known for its high-quality electronic components, including capacitors, inductors, and sensors. Their products are trusted globally for their innovation, reliability, and performance.
• Feature (AEC-Q200 150°C): This indicates compliance with AEC-Q200, the Automotive Electronics Council’s standard for stress test qualification for passive components. The ‘150°C’ further highlights its capability to operate reliably at elevated temperatures, a critical factor in engine compartments and other high-temperature automotive environments.
• AEC-Q200 (YES): Explicitly confirms that the component has undergone and passed the rigorous qualification tests defined by the AEC-Q200 standard, ensuring its suitability for automotive applications.
• Tolerance (±20%): This specifies the permissible deviation of the actual capacitance value from its nominal value. A ±20% tolerance is common for general-purpose and non-precision applications where exact capacitance is not critical, offering a balance between performance and cost.
• L x W Size (1.0mm x 0.5mm [EIA 0402]): This denotes the physical dimensions of the capacitor. The EIA 0402 package is a very small surface-mount device (SMD) size, measuring 1.0mm in length and 0.5mm in width. This compact footprint is crucial for miniaturization in modern electronic assemblies, allowing for higher component density on printed circuit boards.
• Capacitance (680pF): This is the nominal electrical capacitance of the component, measured in picofarads (pF). A capacitance of 680pF is suitable for various filtering, coupling, and timing applications in electronic circuits.
• T(Max.) / mm (0.55): This refers to the maximum thickness of the component, which is 0.55mm. This dimension is important for mechanical design considerations, especially in space-constrained applications.
• Temperature Characteristic (X8R): X8R is a specific dielectric material classification according to EIA standards. It indicates that the capacitance change is within ±15% over an operating temperature range of -55°C to +150°C. This characteristic makes the CGA2B2X8R1H681M050BA highly stable across a wide temperature spectrum, ideal for demanding automotive environments.
• Component Type (Ceramic Capacitor (MLCC)): Confirms that it is a Multilayer Ceramic Capacitor, known for its small size, high-frequency performance, and reliability.
• Product Status (Production (NRND)): Indicates that the product is currently in active production but is ‘Not Recommended for New Designs’. This status suggests that while the part is available, designers might consider newer alternatives for future projects.
• 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 ample headroom for typical automotive 12V or 24V systems, ensuring robust operation.
• Capacitance Change or Temp. Coef. (±15%): This reiterates the stability of the capacitance over the specified temperature range, directly correlating with the X8R dielectric characteristic.
• Operating Temp. Range / °C (-55 to 150): This specifies the full temperature range over which the capacitor is designed to operate reliably, from extreme cold to very high temperatures, making it suitable for diverse automotive applications.

Features and Benefits
