• AEC-Q200: YES – Explicit confirmation of compliance with the AEC-Q200 standard, which is crucial for components used in automotive systems where failure can have significant consequences.
• Tolerance: ±10% – This indicates the permissible deviation of the actual capacitance value from the nominal 680nF. A ±10% tolerance is common for general-purpose and semi-precision applications, offering a good balance between cost and performance.
• L x W Size: 2.0mm x 1.25mm [EIA 0805] – This specifies the physical dimensions of the capacitor, corresponding to the industry-standard 0805 package size. This compact size allows for space-saving designs on printed circuit boards.
• Capacitance: 680nF – The nominal capacitance value of 680 nanofarads, indicating its energy storage capacity. This value is suitable for various filtering, coupling, and decoupling applications.
• T(Max.) / mm: 1.5 – This refers to the maximum thickness of the component, which is important for mechanical design and assembly considerations, especially in compact electronic modules.
• Temp. Chara.: X8R – The temperature characteristic X8R denotes a dielectric material that offers a capacitance change of ±15% over an operating temperature range of -55°C to +150°C. This makes it ideal for high-temperature environments.
• Component Type: Ceramic Capacitor (MLCC) – This identifies it as a Multi-Layer Ceramic Capacitor, known for its small size, high reliability, and excellent frequency characteristics.
• Product Status: Production – Indicates that the component is actively being manufactured and is readily available for new designs and mass production.
• Rated Voltage [DC] / V: 25 – The maximum DC voltage that can be continuously applied to the capacitor without risk of breakdown. A 25V rating is suitable for many low to medium voltage automotive and industrial control circuits.
• Cap.Change or Temp.Coef.: ±15% – This reiterates the capacitance change over the specified temperature range, confirming the X8R dielectric’s performance.
• Operating Temp. Range / °C: -55 to 150 – This broad temperature range signifies the capacitor’s ability to operate reliably in extreme cold and hot conditions, typical of under-the-hood automotive applications.

Features and Benefits

• High Reliability in Harsh Environments: AEC-Q200 qualification and an operating temperature range of -55°C to +150°C ensure robust performance and longevity in demanding automotive and industrial settings.
• Stable Performance at High Temperatures: The X8R temperature characteristic with a ±15% capacitance change up to 150°C provides consistent circuit performance even under elevated thermal stress.
• Compact and Space-Saving Design: The EIA 0805 package size (2.0mm x 1.25mm) allows for miniaturization of electronic modules, crucial for modern automotive systems with limited space.
• Trusted TDK Quality: Manufactured by TDK, this capacitor benefits from decades of expertise in passive components, ensuring high-quality materials and manufacturing processes for superior electrical characteristics.
• Enhanced Mechanical Integrity: The inclusion of “150°C Glue” as a feature suggests improved adhesion and structural stability, particularly important for components subjected to vibration and thermal cycling.

Typical Applications

• Automotive Engine Control Units (ECUs): Used for filtering power lines, decoupling ICs, and timing circuits, ensuring stable operation of critical engine management functions under varying temperatures and vibrations.
• Infotainment and Advanced Driver-Assistance Systems (ADAS): Provides stable power delivery and noise suppression for sensitive electronic modules such as navigation systems, multimedia units, and sensor arrays in ADAS, contributing to reliable data processing.
• LED Lighting Systems in Vehicles: Employed in DC-DC converters and filtering stages for automotive LED headlights, taillights, and interior lighting, ensuring flicker-free operation and extended lifespan of LED drivers.
• Industrial Control and Automation: Suitable for use in robust industrial equipment, sensors, and control modules that operate in environments with wide temperature fluctuations, providing reliable signal integrity and power conditioning.
• Power Supply Decoupling: Essential for decoupling integrated circuits (ICs) in various automotive and high-reliability applications, minimizing voltage fluctuations and preventing noise propagation across the circuit board.
