Key Specifications

• Applications: Automotive Grade: This designation signifies that the capacitor is specifically engineered and tested to meet the rigorous standards required for automotive electronics, ensuring reliability and performance in harsh vehicle environments.
• Brand: TDK: TDK is a renowned Japanese multinational electronics company known for its high-quality electronic components, particularly in the capacitor and inductor markets, guaranteeing a product built to exacting standards.
• Feature: AEC-Q200 MidMega: “AEC-Q200” confirms compliance with the Automotive Electronics Council’s stress test qualification for passive components, indicating suitability for automotive use. “MidMega” likely refers to a specific internal TDK series or technology, possibly related to its capacitance value or size within their automotive portfolio.
• AEC-Q200: YES: Explicitly states compliance with the AEC-Q200 standard, a crucial certification for components used in automotive applications, ensuring they can withstand extreme temperatures, vibrations, and electrical stresses.
• Tolerance: ±10%: This indicates the permissible deviation of the actual capacitance value from the nominal 470nF. A ±10% tolerance is common for general-purpose and many automotive applications, offering a good balance between precision and cost.
• L x W Size: 5.7mm x 5.0mm [EIA 2220]: Describes the physical dimensions of the component, with a length of 5.7mm and a width of 5.0mm. The EIA 2220 designation is a standard package size code, indicating a relatively large surface-mount device suitable for higher power or capacitance applications.
• Capacitance: 470nF: The nominal capacitance value is 470 nanofarads (0.47 microfarads). This value is suitable for a wide array of filtering, coupling, and bypass applications in power supply circuits and signal conditioning.
• T(Max.) / mm: 3.5: Specifies the maximum thickness of the component as 3.5 millimeters. This dimension is important for PCB layout and enclosure design, especially in space-constrained automotive modules.
• Temperature Characteristic: X7T: This is an EIA temperature characteristic code. X7T indicates that the capacitance change will be within +22% to -33% over an operating temperature range of -55°C to +125°C. This characteristic is suitable for automotive applications where stable performance across a broad temperature range is essential.
• Component Type: Ceramic Capacitor (MLCC): Confirms it is a Multi-Layer Ceramic Capacitor, known for its small size, high-frequency performance, and reliability.
• Product Status: Production: Indicates that the component is actively being manufactured and is available for mass production, ensuring long-term supply and support.
• Rated Voltage [DC] / V: 630: The maximum DC voltage that can be continuously applied to the capacitor without risk of breakdown. A 630V rating provides a substantial margin for many automotive power systems, including those with higher voltage rails or transient spikes.
• Cap. Change or Temp. Coef.: +22,-33%: This reiterates the capacitance change over the specified operating temperature range, directly corresponding to the X7T temperature characteristic.
• Operating Temp. Range / °C: -55 to 125: Defines the ambient temperature range within which the capacitor is designed to operate reliably. This wide range is critical for automotive applications, which must function in extreme cold and heat.

Features and Benefits

• Automotive Grade Reliability: Fully compliant with AEC-Q200 standards, ensuring exceptional robustness and long-term reliability in the demanding environmental conditions of automotive systems, including extreme temperatures, vibrations, and humidity.
• High Voltage Capability: With a rated voltage of 630V DC, this capacitor is well-suited for applications requiring robust voltage handling, providing a significant safety margin against voltage spikes and transients common in automotive power lines.
• Wide Operating Temperature Range: The -55°C to +125°C operating range, coupled with the X7T temperature characteristic, guarantees stable electrical performance and capacitance values across the diverse thermal environments encountered in vehicles.
• Compact and Efficient Design: Despite its high capacitance and voltage rating, the EIA 2220 package (5.7mm x 5.0mm) offers a balance between component size and performance, facilitating efficient PCB layout in space-constrained automotive modules.
• Trusted TDK Quality: Manufactured by TDK, a leader in passive components, ensuring high-quality materials, precise manufacturing processes, and consistent performance, which translates to reduced failure rates and enhanced system reliability.
