Key Specifications

This TDK CGA9P4X7T2W105M250KE MLCC boasts several critical specifications that define its capabilities and suitability for specific designs:

Applications: Automotive Grade – This designation signifies that the capacitor is specifically engineered and tested to meet the rigorous requirements of automotive electronics, including resistance to vibration, temperature extremes, and electrical transients. This is crucial for systems where failure could have significant safety or operational implications.

Brand: TDK – TDK is a renowned Japanese multinational electronics company known for its high-quality passive components, magnetic products, and other electronic devices. Their brand signifies reliability and innovation in the electronics industry.

Feature: AEC-Q200 MidSoft – AEC-Q200 is a fundamental stress test qualification for passive components used in automotive applications. The “MidSoft” feature indicates that this capacitor incorporates a soft termination structure, which helps to mitigate stress on the component due to board flexure or thermal cycling, thereby enhancing its mechanical robustness and reliability in demanding environments.

AEC-Q200: YES – Explicitly confirming AEC-Q200 qualification, this ensures the component has undergone and passed the necessary tests for automotive-grade reliability, making it suitable for critical automotive systems.

Tolerance: ±20% – This specifies the permissible deviation of the actual capacitance value from its nominal value. A ±20% tolerance is common for general-purpose decoupling and filtering applications where precise capacitance is not the most critical factor.

L x W Size: 5.7mm x 5.0mm [EIA 2220] – This indicates the physical dimensions of the capacitor, corresponding to the EIA 2220 standard package size. This large size often allows for higher capacitance values and voltage ratings, making it suitable for power applications or where space is less constrained.

Capacitance: 1μF – This is the nominal capacitance value, representing the component’s ability to store charge. A 1 microfarad (μF) capacitor is commonly used for decoupling power lines, filtering low-frequency noise, and energy storage in various circuits.

T(Max.) / mm: 2.8 – This refers to the maximum thickness of the component, which is important for mechanical design and ensuring proper clearance on a PCB.

Temp. Chara.: X7T – The X7T temperature characteristic defines how the capacitance changes over a specified temperature range. For X7T, the capacitance change is within +22% to -33% over the operating temperature range of -55°C to +125°C, making it suitable for applications requiring stable performance across wide temperature variations, typical in automotive settings.

Component Type: Ceramic Capacitor (MLCC) – This identifies the fundamental type of capacitor. MLCCs are known for their small size, high reliability, and excellent frequency response, making them ubiquitous in modern electronics.

Product Status: Production – This confirms that the component is actively being manufactured and is readily available for new designs and mass production.

Rated Voltage [DC] / V: 450 – This is the maximum DC voltage that can be continuously applied across the capacitor without causing damage. A 450V rating makes this component suitable for higher voltage power supply filtering and energy storage applications.

Cap.Change or Temp.Coef.: +22,-33% – This reiterates the capacitance change over the operating temperature range, directly correlating with the X7T temperature characteristic.

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. This wide range is essential for automotive applications that experience extreme hot and cold conditions.
