Key Specifications

The attributes of the CGA2B2X8R2A331K050BE are meticulously engineered to provide robust performance. Its Automotive Grade designation signifies compliance with stringent industry standards, making it suitable for demanding vehicle environments. The Brand, TDK, is synonymous with quality and innovation in the electronics industry. A key Feature is its AEC-Q200 Mid 150°C Soft termination, indicating it is qualified to the automotive industry’s reliability standard, operates at an extended maximum temperature of 150°C, and incorporates soft terminations to mitigate mechanical stress, enhancing durability. The explicit AEC-Q200 qualification (YES) confirms its suitability for automotive applications. A Tolerance of ±10% on its capacitance ensures that the component operates within a narrow, predictable range, which is vital for precise circuit design. The compact L x W Size of 1.0mm x 0.5mm, corresponding to the EIA 0402 standard, allows for high-density mounting on PCBs. With a Capacitance of 330pF, it is ideal for high-frequency filtering and coupling applications. The maximum T(Max.) / mm of 0.6mm indicates its low profile, further aiding miniaturization. The Temp. Chara. of X8R denotes a dielectric material capable of operating from -55°C to +150°C with a maximum capacitance change of ±15%, making it suitable for extreme temperature variations. The Component Type is clearly identified as a Ceramic Capacitor (MLCC). Its Product Status as Production (NRND – Not Recommended for New Designs) suggests it is a mature product, readily available for existing designs. The Rated Voltage [DC] / V of 100V specifies the maximum DC voltage it can withstand continuously without breakdown. Finally, the Operating Temp. Range / °C of -55 to 150°C confirms its robust performance across a very broad thermal spectrum, essential for automotive under-the-hood or cabin electronics.
