CGA9Q1C0G2J104J280KC CGA9Q1C0G2J104J280KC Ceramic Capacitor (MLCC)

CGA9Q1C0G2J104J280KC is a high-performance, automotive-grade multilayer ceramic capacitor (MLCC) manufactured by TDK, a global leader in electronic components. This passive component is specifically designed to meet the rigorous demands of automotive electronics, providing stable capacitance and reliable operation across a wide range of temperatures and environmental conditions. As a ceramic capacitor, its primary function is to store and release electrical energy, filter noise, and stabilize voltage in electronic circuits, making it an indispensable part of modern automotive systems.

Key Specifications

The attributes of the CGA9Q1C0G2J104J280KC are meticulously engineered for demanding applications. Its Automotive Grade designation, coupled with AEC-Q200Mid compliance, signifies that it has undergone stringent testing and meets the qualification standards for automotive components, ensuring reliability in harsh environments. The Brand, TDK, is synonymous with quality and innovation in the electronics industry. With a Capacitance of 100nF (nanofarads), this capacitor is suitable for a wide array of filtering, coupling, and decoupling applications. A tight Tolerance of ±5% ensures that the actual capacitance value is very close to the nominal value, which is critical for precision circuits. The physical dimensions are 5.7mm x 5.0mm [EIA 2220], indicating a relatively larger surface-mount package size suitable for power applications or where higher voltage ratings are required. The maximum thickness, T(Max.) / mm, is 3.1mm, allowing for robust construction. The Temp. Chara. is C0G, which is a highly stable dielectric material characterized by a very low Cap.Change or Temp.Coef. of 0±30ppm/°C, meaning its capacitance changes minimally with temperature variations. This stability is crucial for timing and resonant circuits. A high Rated Voltage [DC] / V of 630V makes it suitable for applications with significant voltage swings or higher DC bus voltages. Finally, an extensive Operating Temp. Range / °C of -55 to 125°C further underscores its suitability for extreme automotive environments, from cold starts to engine compartment heat.
