Key Specifications

• Apps. (Automotive Grade): This attribute signifies that the capacitor is specifically designed and qualified for use in automotive electronics. Components designated as “Automotive Grade” meet stringent reliability and performance standards required for safety-critical and long-life applications in vehicles, such as engine control units, infotainment systems, and advanced driver-assistance systems (ADAS).
• Brand (TDK): TDK is a renowned Japanese multinational electronics company known for its high-quality passive components, including capacitors, inductors, and ferrites. Their brand presence assures engineers of reliable performance and adherence to industry standards.
• Feature (AEC-Q200General) & AEC-Q200 (YES): AEC-Q200 is a global standard for stress test qualification for passive electronic components used in automotive applications. The “YES” indicates full compliance, meaning the capacitor has undergone rigorous testing for temperature cycling, humidity, vibration, and other environmental stresses, ensuring its suitability for the automotive environment.
• Tolerance (±10%): This specifies the permissible deviation of the actual capacitance value from its nominal value (470nF). A ±10% tolerance is common for general-purpose and automotive-grade capacitors, indicating a reasonable level of precision for most applications.
• L x W Size (1.6mm x 0.8mm [EIA 0603]): This refers to the physical dimensions of the surface-mount device (SMD) package. The 0603 EIA standard size is a widely adopted miniature footprint, enabling high-density circuit board designs in compact automotive modules.
• Capacitance (470nF): This is the fundamental electrical property of the capacitor, representing its ability to store charge. A capacitance of 470 nanofarads (nF) is suitable for a wide range of filtering, coupling, and decoupling applications in automotive circuits.
• T(Max.) / mm (0.9): This indicates the maximum thickness of the component, which is 0.9mm. This dimension is critical for mechanical design and ensuring proper clearance in densely packed PCBs.
• Temp. Chara. (X7R) & Cap.Change or Temp.Coef. (±15%): X7R is a common dielectric material for ceramic capacitors, known for its relatively stable capacitance over a wide temperature range. The ±15% capacitance change over the operating temperature range signifies that while it’s stable, there will be some variation, which is acceptable for many automotive applications where precise capacitance is not always critical.
• Component Type (Ceramic Capacitor (MLCC)): MLCC stands for Multi-Layer Ceramic Capacitor, indicating its construction. These capacitors are formed by stacking multiple layers of ceramic dielectric and metal electrodes, allowing for high capacitance values in small packages.
• Product Status (Production): This confirms that the component is actively being manufactured and is readily available for purchase and integration into new designs.
• Rated Voltage [DC] / V (35): This is the maximum DC voltage that can be continuously applied across the capacitor without causing damage or premature failure. A 35V rating provides a sufficient margin for typical 12V or 24V automotive power systems.
• 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 electrical specifications. The wide range from -55°C to 125°C is essential for automotive applications, which must function in extreme hot and cold environments.
