CGJ3E2X7R2A472K080AA

Overview

CGJ3E2X7R2A472K080AA is a high-reliability grade Ceramic Capacitor (MLCC) manufactured by TDK, a global leader in electronic components. This specific component is designed for demanding applications, offering stable capacitance and robust performance. As a Multilayer Ceramic Capacitor, it functions primarily as an energy storage device, filtering, bypassing, and coupling signals in various electronic circuits. Its compact size and excellent electrical characteristics make it an indispensable component in modern electronics, particularly where space is at a premium and reliability is paramount. TDK’s reputation for quality ensures that this capacitor meets stringent performance standards, even for applications requiring AEC-Q200 qualification.

Key Specifications

• Apps. (High Reliability Grade): This attribute signifies that the capacitor is engineered for applications where failure is not an option. Components with a “High Reliability Grade” undergo more rigorous testing and quality control processes to ensure consistent performance over extended periods and under challenging environmental conditions. This is crucial for critical systems where dependability is paramount.
• Brand (TDK): TDK is a renowned Japanese multinational electronics company known for its high-quality electronic components, including passive components like capacitors. Specifying TDK assures buyers of a product backed by extensive research, development, and manufacturing expertise, leading to superior performance and longevity.
• Feature (AEC-Q200Mid) & AEC-Q200 (YES): AEC-Q200 is a global standard for stress test qualification for passive electronic components used in automotive applications. “AEC-Q200Mid” indicates that this component meets the mid-level requirements of this standard, while “YES” confirms its full compliance. This qualification is vital for designers working on automotive electronics, ensuring the component can withstand the harsh conditions (temperature, vibration, humidity) typically found in vehicles.
• Tolerance (±10%): Capacitance tolerance indicates the permissible deviation from the nominal capacitance value. A ±10% tolerance means the actual capacitance value will fall within 10% above or below the stated 4.7nF. This level of tolerance is common for general-purpose and many precision applications, ensuring predictable circuit behavior.
• L x W Size (1.6mm x 0.8mm [EIA 0603]): This specifies the physical dimensions of the surface-mount device (SMD) capacitor. The 1.6mm x 0.8mm size corresponds to the industry-standard EIA 0603 package code. This compact footprint is highly desirable in modern electronics, enabling miniaturization and high-density PCB layouts, which are critical for portable devices and space-constrained applications.
• Capacitance (4.7nF): This is the fundamental electrical property of the capacitor, representing its ability to store an electrical charge. A capacitance of 4.7 nanofarads (nF) is suitable for a wide range of filtering, coupling, and timing applications in various electronic circuits.
• T(Max.) / mm (0.9): This indicates the maximum thickness of the component, which is 0.9mm. This dimension is important for mechanical design and ensuring proper clearance and fit within an enclosure or alongside other components on a PCB.
• 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 associated capacitance change or temperature coefficient of ±15% over the full operating temperature range means that the capacitance value will not deviate by more than 15% from its nominal value between -55°C and 125°C. This makes X7R capacitors suitable for applications where temperature stability is important but not as critical as C0G/NP0 dielectrics.
• Component Type (Ceramic Capacitor (MLCC)): This identifies the fundamental type of component. MLCCs are widely used due to their small size, low equivalent series resistance (ESR), and good high-frequency performance.
• Product Status (Obsolete): This indicates that the manufacturer has discontinued the production of this specific part number. While it may still be available from distributors with existing stock, it is no longer actively manufactured. Designers should consider this for new designs and plan for alternative components for long-term production.
• Rated Voltage [DC] / V (100): This is the maximum DC voltage that can be continuously applied across the capacitor without risking damage or premature failure. A 100V rating provides a good margin for many common circuit voltages, ensuring robust operation.
• Operating Temp. Range / °C (-55 to 125): This specifies the ambient temperature range within which the capacitor is designed to operate reliably and meet its specified performance characteristics. The wide range from -55°C to 125°C highlights its suitability for industrial, automotive, and other demanding environments.
