Key Specifications

Applications: High Reliability Grade: This attribute signifies that the CGJ4J2X7R1C225AA capacitor is engineered for use in critical systems where failure is unacceptable. Components with this designation undergo more stringent testing and quality control processes to ensure robust performance and longevity, making them ideal for automotive, industrial, and medical electronics.

Brand: TDK: TDK is a renowned Japanese multinational electronics company known for its high-quality passive components, including capacitors, inductors, and ferrites. Choosing a TDK component ensures adherence to global manufacturing standards and reliable performance.

Feature: AEC-Q200 General: The AEC-Q200 qualification is a global standard for passive electronic components used in automotive applications. “General” indicates it meets the baseline requirements for use in non-safety-critical automotive systems, demonstrating its robustness against environmental stresses such as temperature, humidity, and vibration.

AEC-Q200: YES: Explicitly confirming its AEC-Q200 compliance, this capacitor is suitable for integration into automotive electronic control units (ECUs), infotainment systems, and other vehicle electronics where reliability under harsh conditions is paramount.

Tolerance: ±10%: This specifies the permissible deviation of the actual capacitance value from its nominal value. A ±10% tolerance is common for general-purpose and many high-reliability applications, providing a good balance between precision and cost-effectiveness.

L x W Size: 2.0mm x 1.25mm [EIA 0805]: This denotes the physical dimensions of the capacitor in millimeters, corresponding to the EIA 0805 standard package size. This compact footprint is widely used in surface-mount technology (SMT) designs, enabling miniaturization of electronic devices.

Capacitance: 2.2μF: The capacitance value of 2.2 microfarads indicates its ability to store a significant amount of electrical charge. This value is commonly used for decoupling power lines, filtering low-frequency noise, and energy storage in various circuits.

T(Max.) / mm: 1.45: This refers to the maximum thickness of the component, which is 1.45 millimeters. This dimension is crucial for mechanical design and ensuring proper fit within constrained enclosures or stacked board configurations.

Temp. Chara.: X7R: X7R is a common temperature characteristic for ceramic capacitors, indicating a relatively stable capacitance over a wide temperature range. It specifies that the capacitance change will be within ±15% from its nominal value over an operating temperature range of -55°C to +125°C, making it suitable for industrial and automotive environments.

Component Type: Ceramic Capacitor (MLCC): This confirms it is a multilayer ceramic capacitor, known for its high frequency performance, low equivalent series resistance (ESR), and excellent reliability compared to other capacitor types.

Product Status: Obsolete: This status indicates that the manufacturer, TDK, has discontinued the production of this specific part number. While it may still be available through distributors with existing stock, it is no longer actively manufactured. Designers should consider alternative, currently active components for new designs.

Rated Voltage [DC] / V: 16: This is the maximum DC voltage that can be continuously applied across the capacitor without causing damage. A 16V rating is common for low-voltage digital and analog circuits, including those powered by 3.3V, 5V, or 12V supplies.

Cap.Change or Temp.Coef.: ±15%: This reiterates the capacitance change over the specified temperature range, consistent with the X7R dielectric characteristic. It ensures predictable performance under varying thermal conditions.

Operating Temp. Range / °C: -55 to 125: This wide operating temperature range signifies the capacitor’s ability to function reliably in extreme cold and hot environments, which is essential for automotive, industrial, and outdoor applications.
