Key Specifications

The CGA5H4C0G2J682J115AA boasts a set of specifications that underscore its suitability for robust applications:

• Applications: Automotive Grade – This designation signifies that the capacitor has undergone rigorous testing and meets the stringent reliability and performance standards required for use in automotive electronics, where components are exposed to harsh environmental conditions such as extreme temperatures, vibrations, and humidity.
• Brand: TDK – TDK is a renowned Japanese multinational electronics company known for its high-quality passive components, including capacitors, inductors, and ferrites. Their reputation for innovation and reliability ensures the superior performance of this MLCC.
• Feature: AEC-Q200Mid & AEC-Q200: YES – AEC-Q200 is a global standard for stress test qualification for passive components used in automotive applications. The “YES” indicates full compliance, while “AEC-Q200Mid” suggests it meets the intermediate level of testing, ensuring robust performance under typical automotive operating conditions.
• Tolerance: ±5% – This specifies the permissible deviation of the actual capacitance value from the nominal 6.8nF value. A ±5% tolerance is considered tight for a ceramic capacitor, indicating high precision and making it suitable for applications where exact capacitance values are critical for circuit performance, such as timing circuits or resonant filters.
• L x W Size: 3.2mm x 1.6mm [EIA 1206] – This refers to the physical dimensions of the surface-mount device (SMD) capacitor. The EIA 1206 standard package size is widely adopted, offering a balance between component footprint and power handling capability, making it easy to integrate into various PCB designs.
• Capacitance: 6.8nF – This is the nominal electrical charge storage capacity of the capacitor. A capacitance of 6.8 nanofarads is common for filtering, coupling, and decoupling applications in digital and analog circuits, providing effective noise suppression and signal integrity.
• T(Max.) / mm: 1.3 – This specifies the maximum thickness of the component, which is 1.3 millimeters. This dimension is crucial for mechanical design considerations, especially in compact electronic assemblies where vertical space is limited.
• Temperature Characteristic: C0G – C0G (also known as NP0) is one of the most stable dielectric materials for ceramic capacitors. It signifies a very low change in capacitance over a wide temperature range, specifically 0±30ppm/°C. This makes the CGA5H4C0G2J682J115AA ideal for precision applications where temperature stability is critical.
• Component Type: Ceramic Capacitor (MLCC) – As a Multi-Layer Ceramic Capacitor, it consists of multiple layers of ceramic dielectric and metal electrodes stacked alternately. This construction allows for high capacitance values in a small form factor and offers excellent high-frequency performance.
• Product Status: Production – This indicates that the component is actively being manufactured and is readily available for purchase, ensuring long-term supply and support for new and existing designs.
• Rated Voltage [DC] / V: 630 – This is the maximum DC voltage that can be continuously applied across the capacitor without causing dielectric breakdown. A high rated voltage of 630V makes this capacitor suitable for applications involving higher voltage rails or where significant voltage transients might occur.
• Cap. Change or Temp. Coef.: 0±30ppm/°C – This reiterates the exceptional temperature stability of the C0G dielectric. It means the capacitance will change by no more than ±30 parts per million per degree Celsius over its operating temperature range, ensuring consistent performance.
• Operating Temp. Range / °C: -55 to 125 – This wide operating temperature range demonstrates the capacitor’s robustness, allowing it to function reliably in extreme cold and hot environments, which are typical conditions encountered in automotive and industrial applications.
