Key Specifications

This TDK MLCC boasts a comprehensive set of specifications that define its capabilities and application suitability:

• Apps. (Automotive Grade): This designation signifies that the capacitor is specifically designed and tested to meet the rigorous demands of automotive electronics, ensuring reliability under harsh conditions such as extreme temperatures, vibrations, and electrical transients.
• Brand (TDK): TDK is a renowned Japanese multinational electronics company known for its high-quality passive components, magnetic products, and other electronic devices, ensuring a product backed by extensive research and manufacturing expertise.
• Feature (AEC-Q200Mid) & AEC-Q200 (YES): These attributes confirm that the component complies with AEC-Q200, the Automotive Electronics Council’s standard for stress test qualification for passive components. The “Mid” designation often refers to specific performance levels within this standard, ensuring robust performance in automotive applications.
• Tolerance (±5%): This indicates that the actual capacitance value will be within ±5% of the nominal 8.2nF. A tighter tolerance is critical for precision circuits where exact timing and filtering are required.
• L x W Size (2.0mm x 1.25mm [EIA 0805]): This specifies the physical dimensions of the component, corresponding to the industry-standard 0805 package size. This compact footprint is ideal for space-constrained PCB designs.
• Capacitance (8.2nF): The nominal capacitance value of 8.2 nanofarads, indicating its ability to store electrical charge. This value is suitable for various filtering, coupling, and decoupling applications.
• T(Max.) / mm (1.45): This refers to the maximum thickness of the component, which is 1.45mm. This dimension is important for mechanical design and clearance considerations on a PCB.
• Temp. Chara. (C0G) & Cap.Change or Temp.Coef. (0±30ppm/°C): C0G is a highly stable dielectric material characterized by a very low temperature coefficient of capacitance (0±30ppm/°C). This means its capacitance value changes minimally across its operating temperature range, making it ideal for precision circuits where temperature stability is critical.
• Component Type (Ceramic Capacitor (MLCC)): Confirms its classification as a Multilayer Ceramic Capacitor, known for its small size, high frequency performance, and reliability.
• Product Status (Production): Indicates that the component is actively being manufactured and is readily available for new designs and existing production runs.
• Rated Voltage [DC] / V (100): The maximum DC voltage that can be continuously applied across the capacitor without risk of breakdown. A 100V rating provides a good margin for many automotive and industrial applications.
• Operating Temp. Range / °C (-55 to 125): This broad temperature range signifies the capacitor’s ability to operate reliably from extremely cold conditions to very hot environments, typical of automotive under-the-hood or industrial settings.
