Components with this grade undergo more rigorous testing and quality control processes to ensure long-term stability and performance under harsh conditions.

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 innovation, reliability, and adherence to global manufacturing standards.

Feature (AEC-Q200 Mid): AEC-Q200 is a global standard for stress test qualification for passive components used in automotive electronics. The ‘Mid’ designation suggests it meets a specific level of these rigorous automotive qualifications, indicating its robustness and suitability for automotive-grade applications, even if not the highest tier.

AEC-Q200 (YES): Explicitly stating ‘YES’ confirms that this capacitor is indeed qualified to the AEC-Q200 standard, ensuring its reliability and performance in the demanding automotive environment, which often involves extreme temperatures, vibrations, and electrical stresses.

Tolerance (±5%): This value specifies the permissible deviation of the actual capacitance from its nominal value. A ±5% tolerance is considered precise for many applications, ensuring that the component performs consistently within expected parameters, which is critical for timing circuits, filters, and resonant circuits.

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 EIA 0603 standard size (0.06 x 0.03 inches) is a common package for MLCCs, offering a balance between miniaturization and ease of handling during assembly. Its compact size allows for high-density circuit board designs.

Capacitance (330pF): This is the fundamental electrical property of the capacitor, indicating its ability to store charge. A capacitance of 330 picofarads is suitable for high-frequency filtering, coupling, decoupling, and timing applications in various electronic circuits.

T(Max.) / mm (0.9): This specifies the maximum thickness of the component, which is 0.9mm. This dimension is crucial for mechanical design considerations, especially in space-constrained applications or when stacking components.

Temp. Chara. (C0G): C0G (also known as NP0) is a highly stable dielectric material for ceramic capacitors. It indicates a very low change in capacitance with temperature, making it ideal for precision applications where temperature stability is critical, such as in oscillators, filters, and medical devices.

Component Type (Ceramic Capacitor (MLCC)): This clarifies that the device is a multilayer ceramic capacitor, known for its high volumetric efficiency, excellent frequency response, and reliability.

Product Status (Obsolete): While the product status is ‘Obsolete,’ it means the manufacturer has discontinued its production. However, it may still be available through distributors for existing designs, repairs, or specific project requirements. For new designs, a suitable replacement would typically be sought.

Rated Voltage [DC] / V (200): This is the maximum DC voltage that can be continuously applied across the capacitor without causing damage. A 200V rating provides a substantial margin for many common electronic circuits, ensuring robust operation.

Cap.Change or Temp.Coef. (0±30ppm/°C): This specification, tied to the C0G dielectric, highlights the extremely low temperature coefficient of capacitance. It means the capacitance changes by a maximum of ±30 parts per million per degree Celsius, ensuring exceptional stability over a wide operating temperature range.

Operating Temp. Range / °C (-55 to 125): This defines the ambient temperature range within which the capacitor is designed to operate reliably. A wide range from -55°C to 125°C signifies its suitability for harsh environments, including automotive under-the-hood applications and industrial settings.
