Key Specifications

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

• Apps. (Automotive Grade): This designation signifies that the capacitor is specifically designed and tested to meet the stringent requirements of automotive electronics, ensuring reliable operation in harsh environments characterized by temperature extremes, vibration, and electrical transients.
• Brand (TDK): TDK is a renowned manufacturer known for its high-quality passive components. Choosing a TDK part ensures adherence to rigorous manufacturing standards and consistent performance.
• 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, guaranteeing the component’s robustness and reliability under automotive operating conditions.
• Tolerance (±10%): This specifies the permissible deviation of the actual capacitance value from its nominal value. A ±10% tolerance is common for general-purpose applications, providing a good balance between precision and cost-effectiveness.
• L x W Size (1.0mm x 0.5mm [EIA 0402]): This refers to the physical dimensions of the surface-mount device (SMD). The 0402 EIA standard size is extremely small, enabling high-density circuit board designs and miniaturization of electronic modules, which is crucial in automotive applications.
• Capacitance (68nF): The nominal capacitance value of 68 nanofarads (nF) indicates the component’s ability to store electrical charge. This value is suitable for a wide range of filtering, coupling, and decoupling applications.
• T(Max.) / mm (0.55): This denotes the maximum thickness of the component, which is important for mechanical design and ensuring proper fit within compact enclosures.
• Temp. Chara. (X7R) & Cap.Change or Temp.Coef. (±15%): X7R is a common dielectric material for ceramic capacitors, known for its stable performance over a wide temperature range. The ±15% capacitance change over the operating temperature range indicates good thermal stability, making it suitable for applications where temperature variations are expected.
• Component Type (Ceramic Capacitor (MLCC)): This identifies the fundamental type of component, highlighting its construction from multiple layers of ceramic dielectric and metal electrodes.
• Product Status (Production): This indicates that the component is actively being manufactured and is readily available for purchase and integration into new designs.
• Rated Voltage [DC] / V (25): This is the maximum DC voltage that can be continuously applied across the capacitor without risk of dielectric breakdown. A 25V rating is suitable for many low-voltage automotive control and sensor circuits.
• Operating Temp. Range / °C (-55 to 125): This broad temperature range signifies the capacitor’s ability to operate reliably from extreme cold to high heat, a critical requirement for components used in engine compartments or other challenging automotive environments.
