Key Specifications

The CGA4J1X8L1V225K125AE boasts several critical specifications that define its performance and suitability for various applications:

• Applications: Automotive Grade – This designation signifies that the capacitor is specifically engineered and tested to meet the rigorous demands of automotive electronics, including extreme temperatures, vibrations, and electrical transients.
• Brand: TDK – TDK is a renowned Japanese multinational electronics company known for its high-quality passive components, ensuring reliability and advanced technological design.
• Feature: AEC-Q200 150°C Soft – This indicates compliance with AEC-Q200, the automotive industry standard for passive components, guaranteeing reliability under harsh conditions. The “150°C Soft” feature suggests robust performance up to 150°C and potentially a soft termination structure to mitigate board flex cracking.
• AEC-Q200: YES – Explicit confirmation of compliance with the Automotive Electronics Council’s component qualification standard, crucial for automotive system integration.
• Tolerance: ±10% – This specifies the permissible deviation of the actual capacitance value from its nominal value, indicating a good level of precision for many automotive and industrial applications.
• L x W Size: 2.0mm x 1.25mm [EIA 0805] – This is the physical dimension of the component, corresponding to the industry-standard 0805 package size, which is a common footprint for surface-mount devices, balancing compactness with ease of handling.
• Capacitance: 2.2μF – The nominal capacitance value, indicating its ability to store electrical charge. A 2.2μF capacitor is suitable for various filtering, decoupling, and energy storage tasks.
• T(Max.) / mm: 1.5 – The maximum thickness of the component, important for board layout and clearance considerations in compact designs.
• Temp. Chara.: X8L – This temperature characteristic defines the capacitance change over a specified temperature range. X8L indicates a capacitance change of +15% to -40% over an operating temperature range of -55°C to +150°C, making it suitable for high-temperature environments.
• Component Type: Ceramic Capacitor (MLCC) – Multilayer Ceramic Capacitors are known for their small size, high frequency response, and excellent reliability.
• Product Status: Production – This confirms that the component is actively manufactured and available for new designs and mass production.
• Rated Voltage [DC] / V: 35 – The maximum DC voltage that can be continuously applied to the capacitor without risk of breakdown, providing a good margin for 12V and 24V automotive systems.
• Cap.Change or Temp.Coef.: +15,-40% – This reiterates the capacitance change performance over the full operating temperature range, directly related to the X8L characteristic.
• Operating Temp. Range / °C: -55 to 150 – This wide temperature range highlights the capacitor’s robustness and suitability for extreme automotive environments, from cold starts to under-the-hood operation.

Features and Benefits
