Key Specifications

• Apps. (Automotive Grade): This attribute signifies that the CGA3E2X7R1H682K080AA capacitor is specifically designed and qualified for use in automotive electronics. Components designated as ‘Automotive Grade’ must meet stringent reliability and performance standards to withstand the harsh conditions (temperature extremes, vibration, humidity) typically found in vehicles, ensuring long-term stability and safety.
• Brand (TDK): TDK is a renowned Japanese multinational electronics company known for its high-quality electronic components, including capacitors, inductors, and magnetic products. Specifying TDK ensures a product from a trusted manufacturer with a reputation for innovation and reliability in the electronics industry.
• Feature (AEC-Q200General) & AEC-Q200 (YES): AEC-Q200 is a global standard for stress test qualification for passive electronic components used in automotive applications. The ‘YES’ indicates that this capacitor has successfully passed all the rigorous tests outlined in the AEC-Q200 standard, confirming its suitability and reliability for automotive environments.
• Tolerance (±10%): This value indicates the permissible deviation of the actual capacitance from its nominal value. A ±10% tolerance means the capacitance of the CGA3E2X7R1H682K080AA will be within 10% above or below 6.8nF, which is a common and acceptable range for many general-purpose and automotive applications, providing sufficient precision for stable circuit operation.
• 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 critical for modern compact electronic devices, allowing for high-density circuit board designs and miniaturization of end products.
• Capacitance (6.8nF): This is the fundamental electrical property of the capacitor, indicating its ability to store an electrical charge. A capacitance of 6.8 nanofarads (nF) is suitable for various filtering, coupling, and timing applications in electronic circuits.
• T(Max.) / mm (0.9): This refers to the maximum thickness of the component, which is 0.9mm. This dimension is important for mechanical design considerations, especially in applications where height constraints are critical for product assembly and enclosure design.
• Temp. Chara. (X7R) & Cap.Change or Temp.Coef. (±15%): X7R is a common dielectric material classification for ceramic capacitors, known for its relatively stable performance over a wide temperature range. The ±15% capacitance change over the operating temperature range (-55 to 125 °C) indicates that while there is some variation, it remains within acceptable limits for many automotive and industrial applications where temperature stability is important but not as critical as with C0G/NP0 dielectrics.
• Component Type (Ceramic Capacitor (MLCC)): This identifies the fundamental type of component. MLCCs are widely used due to their small size, high capacitance values, and excellent high-frequency performance.
• Product Status (Production): This indicates that the component is actively being manufactured and is readily available for purchase and integration into new designs, ensuring long-term supply and support.
• 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 voltage margin for many automotive and general electronic circuits, ensuring reliable operation under typical operating conditions.
• Operating Temp. Range / °C (-55 to 125): This specifies the full range of ambient temperatures over which the capacitor is designed to operate reliably and meet its specified performance characteristics. The wide range from -55°C to 125°C is typical for automotive-grade components, allowing for use in extreme hot and cold environments.

Features and Benefits
