As an MLCC, it offers a compact form factor, high capacitance values for its size, and excellent frequency characteristics, making it indispensable in modern electronics. TDK’s commitment to quality ensures that this capacitor, despite its ‘Obsolete’ product status, still represents a robust solution for specific legacy or maintenance requirements where its unique attributes are essential.

Key Specifications

This TDK MLCC boasts several critical specifications that define its performance and suitability for various applications:

Apps. (High Reliability Grade): This designation indicates that the capacitor is engineered for applications where consistent performance and longevity are paramount, often in demanding environments. Components with this grade undergo more stringent testing and quality control processes to ensure dependable operation over extended periods.

Brand (TDK): TDK is a renowned Japanese multinational electronics company known for its high-quality electronic components, including capacitors, inductors, and magnetic products. Their brand signifies reliability, innovation, and adherence to global manufacturing standards.

Feature (AEC-Q200General) and AEC-Q200 (YES): The AEC-Q200 qualification is a critical standard for passive components used in automotive electronics. It ensures that the component meets rigorous stress tests for reliability in harsh automotive environments, including extreme temperatures, humidity, and vibration. The ‘General’ feature suggests broad applicability within this standard, making it suitable for a wide range of automotive and other high-reliability industrial applications.

Tolerance (±10%): This specifies the permissible deviation of the actual capacitance value from its nominal value (33nF). A ±10% tolerance is common for general-purpose and many high-reliability applications, indicating a reasonable level of precision for circuit design.

L x W Size (1.6mm x 0.8mm [EIA 0603]): This refers to the physical dimensions of the surface-mount device (SMD) capacitor. The 0603 EIA standard size is a widely adopted miniature package, allowing for high-density component placement on printed circuit boards (PCBs), crucial for compact electronic devices.

Capacitance (33nF): The nominal capacitance value is 33 nanofarads (33 x 10^-9 Farads). This value determines the capacitor’s ability to store charge and is a primary parameter for filtering, coupling, and timing applications.

T(Max.) / mm (0.9): This indicates the maximum thickness of the component, which is 0.9mm. This dimension is important for mechanical design, ensuring proper clearance and fit within an enclosure or between other components on a PCB.

Temp. Chara. (X7R): X7R is a common dielectric material classification for ceramic capacitors, known for its relatively stable capacitance over a wide temperature range. It is suitable for applications where capacitance change with temperature is a concern, but not as critical as C0G/NP0 dielectrics.

Rated Voltage [DC] / V (50): This is the maximum DC voltage that can be continuously applied across the capacitor without causing dielectric breakdown or damage. A 50V rating makes it suitable for many low to medium voltage power supply and signal processing circuits.

Cap.Change or Temp.Coef. (±15%): For X7R dielectrics, this specifies that the capacitance can vary by no more than ±15% over its full operating temperature range (-55 to 125 °C), relative to its value at 25 °C. This characteristic is crucial for designers to account for performance variations under different thermal conditions.

Operating Temp. Range / °C (-55 to 125): This defines the ambient temperature range within which the capacitor is designed to operate reliably. The wide range from -55°C to 125°C highlights its suitability for industrial, automotive, and other demanding environments where extreme temperatures are encountered.
