AEC-Q200 certification confirms that the component meets the Automotive Electronics Council’s stress test qualification for passive components, ensuring its suitability for automotive use. The “150°C Glue” indicates that the component is designed to withstand and operate reliably at temperatures up to 150°C, often utilizing specialized high-temperature adhesives in its construction for enhanced durability.
• AEC-Q200: YES: Explicitly confirming AEC-Q200 compliance, this attribute guarantees that the capacitor has undergone and passed the rigorous qualification tests established by the Automotive Electronics Council, making it suitable for automotive applications where reliability is paramount.
• Tolerance: ±10%: This value indicates the permissible deviation of the actual capacitance from its nominal value. A ±10% tolerance is common for general-purpose and automotive applications, providing a good balance between precision and cost-effectiveness for many circuit designs.
• L x W Size: 3.2mm x 1.6mm [EIA 1206]: This specifies the physical dimensions of the capacitor. The 3.2mm x 1.6mm size corresponds to the industry-standard EIA 1206 package code, which is a widely used surface-mount technology (SMT) footprint, offering a balance between component size and ease of handling during assembly.
• Capacitance: 470nF: This is the nominal capacitance value of the component, expressed as 470 nanofarads (0.47 microfarads). This value determines the capacitor’s ability to store electrical charge and is crucial for filtering, coupling, and timing applications in electronic circuits.
• T(Max.) / mm: 1: This refers to the maximum thickness of the component, which is 1 millimeter. This dimension is important for mechanical design and ensuring proper fit within compact electronic assemblies, especially in space-constrained automotive modules.
• Temp. Chara.: X8R: X8R is a specific dielectric material classification according to EIA standards. It indicates that the capacitor exhibits a capacitance change of no more than ±15% over an operating temperature range of -55°C to +150°C, making it highly suitable for high-temperature automotive environments.
• Component Type: Ceramic Capacitor (MLCC): This identifies the fundamental type of component. MLCCs (Multi-Layer Ceramic Capacitors) are known for their small size, high capacitance values, low equivalent series resistance (ESR), and excellent high-frequency performance, making them versatile for various applications.
• Product Status: Production: This status indicates that the component is actively being manufactured and is readily available for purchase and integration into new designs or existing production lines, ensuring long-term supply stability.
• Rated Voltage [DC] / V: 25: This is the maximum DC voltage that the capacitor can continuously withstand without breakdown. A 25V rating is suitable for many automotive low-voltage power rails and signal processing circuits.
• Cap.Change or Temp.Coef.: ±15%: This reiterates the capacitance change over temperature, specifically for the X8R dielectric. It means that the capacitance value will not vary by more than ±15% from its nominal value across the specified operating temperature range, ensuring stable performance.
• Operating Temp. Range / °C: -55 to 150: This defines the full range of ambient temperatures within which the capacitor is designed to operate reliably and meet its specified performance characteristics. The wide range, extending to 150°C, is critical for automotive under-hood and other high-temperature applications.
