Key Specifications

• Applications: Automotive Grade
  This designation means the capacitor is specifically engineered and tested to withstand the rigorous conditions found in automotive environments, including extreme temperatures, vibrations, and electrical transients. It ensures long-term reliability in critical vehicle 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 signifies reliability and advanced technology in the electronics industry.
• Feature: AEC-Q200 Soft Termination
  The AEC-Q200 certification indicates compliance with the Automotive Electronics Council’s standard for passive components, ensuring suitability for automotive applications. “Soft Termination” is a crucial feature that incorporates a flexible conductive layer in the capacitor’s termination, significantly enhancing its resistance to thermal and mechanical stresses, thereby preventing cracking and improving overall reliability in demanding conditions.
• AEC-Q200: YES
  Explicitly confirms that the component meets the rigorous AEC-Q200 standard, which is essential for any electronic component used in automotive systems to ensure performance and durability under harsh operating conditions.
• Tolerance: ±5%
  This indicates the permissible deviation of the actual capacitance value from its nominal value. A ±5% tolerance is a relatively tight tolerance for a ceramic capacitor, signifying higher precision and suitability for applications where exact capacitance values are critical for circuit performance.
• L x W Size: 2.0mm x 1.25mm [EIA 0805]
  This specifies the physical dimensions of the capacitor. The 0805 EIA (Electronic Industries Alliance) standard size is a common surface-mount device (SMD) package, offering a good balance between miniaturization and ease of handling during assembly.
• Capacitance: 33nF (nanofarads)
  This is the nominal electrical charge storage capacity of the capacitor. A 33nF capacitance is suitable for a wide range of filtering, coupling, and timing applications in electronic circuits.
• T(Max.) / mm: 1.5
  Indicates the maximum thickness of the component, which is 1.5 millimeters. This dimension is important for PCB layout and ensuring proper fit within the designated space in an electronic assembly.
• Temperature Characteristic: C0G
  C0G is one of the most stable dielectric materials for ceramic capacitors. It signifies a very low change in capacitance over a wide temperature range, specifically 0±30 ppm/°C. This makes it ideal for precision applications where temperature stability is paramount.
• Component Type: Ceramic Capacitor (MLCC)
  Confirms it is a Multilayer Ceramic Capacitor, known for its small size, high-frequency performance, and reliability, especially in surface-mount configurations.
• Product Status: Production
  Indicates that the component is actively being manufactured and is readily available for purchase and integration into new designs.
• Rated Voltage [DC] / V: 50
  This is the maximum DC voltage that can be continuously applied across the capacitor without causing damage. A 50V rating provides a good margin for many automotive and general-purpose electronic circuits.
• Cap. Change or Temp. Coef.: 0±30ppm/°C
  This reiterates the excellent temperature stability of the C0G dielectric, meaning the capacitance will change by no more than ±30 parts per million per degree Celsius over its operating temperature range.
• Operating Temp. Range / °C: -55 to 125
  This broad temperature range demonstrates the capacitor’s robustness, allowing it to function reliably in extreme cold and hot environments, which is critical for automotive applications where components are exposed to varying thermal conditions.
