Key Specifications

• Applications: Automotive Grade
  This designation signifies that the capacitor is engineered and tested to meet the rigorous demands of automotive electronics. Components with this rating are crucial for systems where reliability and performance are paramount, such as engine control units, infotainment systems, and safety features.
• Brand: TDK
  TDK is a renowned Japanese multinational electronics company known for its high-quality electronic components, including capacitors, inductors, and sensors. Their expertise ensures advanced material science and manufacturing precision.
• Feature: AEC-Q200MidSoft
  AEC-Q200 is a global standard for passive electronic components used in automotive applications. The “MidSoft” feature indicates a specific dielectric material or construction that offers enhanced resistance to mechanical stress and thermal shock, which is critical in automotive environments prone to vibration and rapid temperature changes.
• AEC-Q200: YES
  This explicit confirmation means the capacitor fully complies with the Automotive Electronics Council’s AEC-Q200 stress test qualification for passive components, guaranteeing its suitability for automotive use.
• Tolerance: ±10%
  The capacitance value of 1μF is guaranteed to be within ±10% of its nominal value. This tolerance level is suitable for a wide range of applications where precise capacitance is important but not ultra-critical, providing a good balance between performance and cost.
• L x W Size: 5.7mm x 5.0mm [EIA 2220]
  This specifies the physical dimensions of the component, with a length of 5.7mm and a width of 5.0mm. The EIA 2220 designation refers to the industry-standard package size, indicating a relatively large footprint for an MLCC, often chosen for higher capacitance values or voltage ratings.
• Capacitance: 1μF
  This is the nominal electrical charge storage capacity of the capacitor. A 1 microfarad (μF) capacitance is a common value used in power supply filtering, coupling, and decoupling applications in various electronic circuits.
• T(Max.) / mm: 2.8
  This indicates the maximum thickness of the component, which is 2.8 millimeters. This dimension is crucial for PCB layout and ensuring proper clearance in compact electronic assemblies.
• Temperature Characteristic: X7T
  The X7T dielectric characteristic defines the capacitance change over a specific temperature range. For X7T, the capacitance change is within +22% to -33% over an operating temperature range of -55°C to +125°C. This characteristic is robust for automotive applications where wide temperature fluctuations are common.
• Component Type: Ceramic Capacitor (MLCC)
  This identifies the fundamental type of capacitor. MLCCs are highly versatile, offering high capacitance in small packages, excellent frequency response, and good reliability, making them widely used in modern electronics.
• Product Status: Production
  This indicates that the component is actively being manufactured and is readily available for purchase, ensuring long-term supply stability for design and production cycles.
• Rated Voltage [DC] / V: 450
  This is the maximum continuous DC voltage that can be applied across the capacitor without risking damage or premature failure. A 450V rating is substantial, making this capacitor suitable for higher voltage circuits often found in power conversion and automotive systems.
• Capacitance Change or Temperature Coefficient: +22,-33%
  This reiterates the capacitance variation over the specified temperature range, directly correlating with the X7T temperature characteristic. It quantifies the stability of the capacitance value under thermal stress.
• Operating Temperature Range / °C: -55 to 125
  This defines the full range of ambient temperatures within which the capacitor is designed to operate reliably and meet its specified performance characteristics. This wide range is typical for automotive-grade components, which must function in extreme hot and cold conditions.

Features and Benefits

• Exceptional Reliability for Automotive Use: Being AEC-Q200 qualified, the CGA9P4X7T2W105K250KE is rigorously tested to withstand harsh automotive environments, including extreme temperatures, vibrations, and humidity, ensuring long-term operational stability.
• High Voltage Handling Capability: With a rated voltage of 450V DC, this capacitor is well-suited for applications requiring robust voltage suppression and filtering in higher voltage automotive subsystems, contributing to overall system safety and performance.
• Stable Performance Across Wide Temperatures: The X7T temperature characteristic ensures that the 1μF capacitance remains within a predictable range (+22% to -33%) over an extensive operating temperature range of -55°C to +125°C, critical for consistent performance in varying climates.
• Enhanced Mechanical Durability: The AEC-Q200MidSoft feature indicates a design optimized for resistance against mechanical stress and thermal shock, reducing the risk of cracking or failure due to board flex or rapid temperature changes, thereby extending component lifespan.
• Compact and Efficient Design: Despite its high capacitance and voltage rating, the EIA 2220 package (5.7mm x 5.0mm) offers a balance between physical size and electrical performance, allowing for efficient PCB layout in space-constrained automotive modules.

Typical Applications

• Engine Control Units (ECUs): Used for filtering power supply lines, decoupling ICs, and timing circuits within ECUs, where stable and reliable operation is critical for engine management and emissions control.
• Automotive Infotainment Systems: Employed in power conditioning and signal filtering for audio amplifiers, display drivers, and communication modules, ensuring clear sound and stable video output in vehicles.
• Advanced Driver-Assistance Systems (ADAS): Integrated into radar, camera, and sensor modules for noise suppression and voltage stabilization, which are vital for the accurate and reliable functioning of safety features like adaptive cruise control and lane-keeping assist.
• Electric Vehicle (EV) and Hybrid Electric Vehicle (HEV) Power Electronics: Utilized in DC-DC converters, on-board chargers, and battery management systems for filtering and energy storage, contributing to the efficiency and reliability of the vehicle’s electrical powertrain.
