Key Specifications

• Applications: Automotive Grade
  This designation signifies that the capacitor is specifically engineered and tested to meet the rigorous demands of automotive electronics. Components with this rating are subjected to extensive qualification processes to ensure reliability, durability, and performance in environments characterized by extreme temperatures, vibrations, and electrical stresses, which are common in vehicles.
• Brand: TDK
  TDK is a renowned Japanese multinational electronics company known for its high-quality electronic components, including capacitors, inductors, and sensors. Their products are trusted globally for their innovation, reliability, and performance in a wide range of industries.
• Feature: AEC-Q200, MidMEGA I, LowR
  AEC-Q200 certification confirms that the component meets the Automotive Electronics Council’s stress test qualification for passive components, ensuring its suitability for automotive applications. “MidMEGA I” likely refers to a specific internal TDK technology or series indicating a balance of capacitance and size, while “LowR” (Low ESR) highlights its low equivalent series resistance, which is crucial for efficient power delivery and reduced heat generation in high-frequency applications.
• AEC-Q200: YES
  Explicitly confirms the component’s qualification to the AEC-Q200 standard, underscoring its reliability and suitability for automotive electronic systems.
• Tolerance: ±20%
  This indicates the permissible deviation of the actual capacitance value from its nominal value (3.3μF). A ±20% tolerance is common for general-purpose and power filtering applications where precise capacitance is less critical than robustness and cost-effectiveness.
• L x W Size: 5.7mm x 5.0mm [EIA 2220]
  This specifies the physical dimensions of the capacitor. The EIA 2220 designation is an industry standard size code, indicating a relatively large surface-mount package. This larger size often correlates with higher capacitance values and voltage ratings, making it suitable for applications requiring significant energy storage in a compact form factor.
• Capacitance: 3.3μF
  The nominal capacitance value, representing the component’s ability to store electrical charge. A 3.3 microfarad capacitance is substantial for an MLCC, making it suitable for power supply decoupling, filtering, and energy storage in various circuits.
• T(Max.) / mm: 6.9
  This denotes the maximum thickness of the component, which is an important consideration for board layout and overall product height in compact electronic designs.
• Temperature Characteristic: X7T
  X7T is an EIA (Electronic Industries Alliance) code for ceramic capacitor dielectric materials. It indicates that the capacitor can operate within a temperature range of -55°C to +125°C, with a capacitance change of +22% to -33% over this range. This characteristic is suitable for automotive and industrial applications where wide temperature variations are expected.
• Component Type: Ceramic Capacitor (MLCC)
  Confirms the fundamental type of the component, highlighting its multi-layer ceramic construction, which offers high capacitance in a small volume, excellent frequency response, and high reliability.
• Product Status: Production
  Indicates that the component is actively being manufactured and is available for purchase in volume, ensuring long-term supply for new and existing designs.
• Rated Voltage [DC] / V: 350
  This is the maximum DC voltage that can be continuously applied across the capacitor without causing damage or degradation. A 350V rating makes this capacitor suitable for applications involving higher voltage rails, such as in power converters, automotive power systems, and industrial controls.
• Cap. Change or Temp. Coef.: +22, -33%
  This reiterates the capacitance change over the specified operating temperature range, consistent with the X7T dielectric characteristic. It provides designers with crucial information for predicting component behavior under varying thermal conditions.
• Operating Temp. Range / °C: -55 to 125
  Specifies the full range of ambient temperatures within which the capacitor is designed to operate reliably, further emphasizing its suitability for harsh automotive and industrial environments.
