CGA9Q1C0G3A333J280KC CGA9Q1C0G3A333J280KC Ceramic Capacitor (MLCC)

CGA9Q1C0G3A333J280KC is a high-performance, automotive-grade ceramic capacitor (MLCC) manufactured by TDK, a global leader in electronic components. This passive component is crucial for filtering, decoupling, and energy storage in a wide array of electronic circuits, particularly those demanding high reliability and stability in harsh environments. As a multi-layer ceramic capacitor, it offers excellent electrical characteristics, compact size, and robust construction, making it an ideal choice for critical automotive and industrial applications where consistent performance is paramount.

Key Specifications

The CGA9Q1C0G3A333J280KC boasts several key specifications that underscore its suitability for demanding applications. Its Automotive Grade designation, coupled with AEC-Q200 certification, signifies that it has undergone rigorous testing to meet the stringent reliability requirements for automotive electronics. This ensures stable operation under extreme conditions such as wide temperature fluctuations, mechanical shock, and vibration, which are common in vehicle systems. The Capacitance of 33nF (nanofarads) provides a precise charge storage capability, essential for filtering noise, stabilizing voltage rails, and timing circuits. A tight Tolerance of ±5% ensures that the actual capacitance value deviates minimally from the nominal, which is critical for precision applications where exact timing and filtering characteristics are required. The high Rated Voltage [DC] / V of 1000V allows this capacitor to be safely used in high-voltage circuits, providing a significant margin of safety and reliability. The Temp. Chara. of C0G, also known as NP0, indicates an extremely stable temperature coefficient of capacitance, with a Cap.Change or Temp.Coef. of 0±30ppm/°C. This means its capacitance changes negligibly over its wide Operating Temp. Range / °C of -55 to 125°C, making it ideal for applications requiring stable performance across varying thermal conditions. The physical dimensions, L x W Size of 5.7mm x 5.0mm [EIA 2220], denote a relatively large footprint for an MLCC, often chosen for higher capacitance or voltage ratings, while the T(Max.) / mm of 3.1mm specifies its maximum thickness. These dimensions are important for PCB layout and mechanical integration.
