CGA2B2X8R1H681M050BE CGA2B2X8R1H681M050BE Ceramic Capacitor (MLCC)

CGA2B2X8R1H681M050BE

CGA2B2X8R1H681M050BE 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 for demanding applications within the automotive industry, where reliability and performance under extreme conditions are paramount. As a ceramic capacitor, its primary function is to store and release electrical energy, filter noise, and stabilize voltage in various electronic circuits. Its compact size and robust construction make it an ideal choice for space-constrained and mission-critical automotive systems, ensuring stable operation across a wide temperature range and under harsh environmental stresses.

Key Specifications

The CGA2B2X8R1H681M050BE boasts a set of specifications tailored for high-reliability applications. Its Automotive Grade designation, coupled with AEC-Q200 certification, signifies that it has undergone rigorous testing to meet the stringent quality and reliability standards required for automotive electronics. The Brand, TDK, is synonymous with quality and innovation in the passive components market. A key Feature is its AEC-Q200 150°C Soft characteristic, indicating not only automotive qualification but also an extended maximum operating temperature of 150°C and a ‘soft’ termination design to mitigate cracking from board flex. The Tolerance of ±20% on capacitance is typical for general-purpose ceramic capacitors, offering a good balance between precision and cost-effectiveness. With a L x W Size of 1.0mm x 0.5mm [EIA 0402], this component is incredibly compact, making it suitable for miniaturized electronic assemblies. The nominal Capacitance is 680pF (picofarads), a common value for filtering and coupling applications. Its maximum Thickness (T(Max.)) is 0.6mm, contributing to its low-profile design. The Temp. Chara. is X8R, which defines its capacitance change over temperature. For X8R, the Cap. Change or Temp. Coef. is ±15% over the full Operating Temp. Range of -55 to 150°C, making it suitable for applications requiring stable performance in extreme thermal environments. The Rated Voltage [DC] is 50V, indicating the maximum DC voltage that can be continuously applied across the capacitor without breakdown. The Component Type is clearly a Ceramic Capacitor (MLCC), and its Product Status is Production (NRND), meaning it is actively manufactured but may be nearing the end of its lifecycle, though still widely available.

Features and Benefits

• Automotive Grade Reliability: Fully AEC-Q200 qualified, ensuring exceptional reliability and performance in harsh automotive environments, including under-the-hood applications.
