Key Specifications

This TDK CEU4J2X7R2A153K125AE ceramic capacitor boasts several critical specifications that define its performance and suitability for various applications:

• Applications: Automotive Grade – This designation signifies that the capacitor is specifically designed, tested, and qualified for use in automotive electronics, where components must withstand harsh environmental conditions, vibrations, and wide temperature variations. This is crucial for ensuring the reliability and safety of automotive systems.
• 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 assures a commitment to innovation, reliability, and stringent manufacturing standards.
• Feature: AEC-Q200MidSoftSerial – This feature indicates compliance with AEC-Q200, a global standard for stress test qualification for passive electronic components used in automotive applications. “MidSoftSerial” likely refers to specific internal construction or material properties that contribute to enhanced reliability and mechanical robustness, particularly against thermal shock and board flexure.
• AEC-Q200: YES – Explicitly confirms that the component has passed the rigorous AEC-Q200 qualification tests, making it suitable for automotive use.
• Tolerance: ±10% – This specifies the permissible deviation of the actual capacitance value from its nominal value. A ±10% tolerance is common for general-purpose and many automotive applications, indicating a good balance between precision and cost-effectiveness.
• L x W Size: 2.0mm x 1.25mm [EIA 0805] – This denotes the physical dimensions of the capacitor. The 0805 EIA (Electronic Industries Alliance) package size is a standard surface-mount technology (SMT) footprint, widely used for its balance of size, power handling, and ease of assembly in automated manufacturing processes.
• Capacitance: 15nF – The nominal capacitance value is 15 nanofarads (15 x 10^-9 Farads). This value determines the amount of charge the capacitor can store and is critical for filtering, coupling, and timing applications.
• T(Max.) / mm: 1.5 – This indicates the maximum thickness of the component, which is 1.5 millimeters. This dimension is important for PCB layout and ensuring proper clearance in compact designs.
• Temp. Chara.: X7R – X7R is a common dielectric material classification for ceramic capacitors. It is known for its relatively stable capacitance over a wide temperature range, typically from -55°C to +125°C, with a capacitance change of no more than ±15%. This makes it suitable for industrial and automotive applications where temperature stability is crucial.
• Component Type: Ceramic Capacitor (MLCC) – Confirms its fundamental type as 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 purchase in volume, ensuring long-term supply for design and production.
• Rated Voltage [DC] / V: 100 – This is the maximum DC voltage that can be continuously applied across the capacitor without causing damage or degradation. A 100V rating provides a substantial margin for many automotive and industrial power supply applications.
• Cap.Change or Temp.Coef.: ±15% – This reiterates the capacitance change over the specified operating temperature range, consistent with the X7R dielectric characteristics.
• Operating Temp. Range / °C: -55 to 125 – This specifies the full temperature range over which the capacitor is designed to operate reliably and meet its performance specifications. This wide range is essential for automotive environments which experience extreme temperature fluctuations.
