Key Specifications

This TDK ceramic capacitor boasts a set of attributes that define its performance and application suitability:

• Apps. (Automotive Grade): This designation signifies that the capacitor is engineered and tested to meet the stringent requirements of automotive electronics, ensuring reliable operation in vehicles. This is crucial for safety-critical and long-life applications within the automotive sector.
• Brand (TDK): TDK is a renowned Japanese multinational electronics company known for its high-quality passive components. Specifying TDK assures engineers of the component’s reliability, consistent performance, and adherence to global manufacturing standards.
• Feature (AEC-Q200, General, 150°C, Halogen-free): These features highlight the capacitor’s compliance with the Automotive Electronics Council’s AEC-Q200 standard, indicating its qualification for automotive applications. The 150°C rating denotes its capability to operate at elevated temperatures, which is common in engine compartments and other automotive subsystems. Being halogen-free aligns with environmental regulations and green manufacturing practices.
• AEC-Q200 (YES): Explicitly stating “YES” confirms that this component has successfully passed the rigorous stress tests and qualification procedures outlined by the AEC-Q200 standard, making it suitable for automotive use.
• Tolerance (±5%): This indicates the permissible deviation of the actual capacitance value from the nominal 680pF. A ±5% tolerance is considered precise for many automotive and industrial applications, ensuring consistent circuit performance.
• Capacitance (680pF): This is the nominal electrical charge storage capacity of the capacitor. A 680pF capacitance is suitable for high-frequency filtering, coupling, and timing applications in various electronic circuits.
• F(Nom.) / mm (2.5), L(Max.) / mm (4), T(Max.) / mm (2.5), W(Max.) / mm (5.5): These dimensions specify the physical size of the capacitor body. F(Nom.) likely refers to the nominal lead spacing, while L, T, and W represent the maximum length, thickness, and width, respectively. These measurements are critical for PCB layout and mechanical design considerations.
• Temp. Chara. (NP0): NP0 (also known as C0G) is a highly stable dielectric material with a very low temperature coefficient of capacitance. This means its capacitance value changes minimally with temperature variations, making it ideal for precision circuits and resonant applications.
• Component Type (Ceramic Capacitor (Leaded MLCC)): This clearly identifies the component as a ceramic capacitor with multiple layers of dielectric and electrodes, featuring leads for through-hole mounting.
• Product Status (Production): This indicates that the component is actively being manufactured and is available for purchase in volume, assuring long-term supply for design and production cycles.
• Rated Voltage [DC] / V (50): This is the maximum DC voltage that can be continuously applied across the capacitor without risking damage or breakdown. A 50V rating provides sufficient headroom for many automotive 12V and 24V systems.
• Lead Length / Package Type (Taping): “Taping” specifies that the leaded components are supplied on a tape and reel, which is a standard packaging method for automated assembly processes, improving manufacturing efficiency.
