Key Specifications

The attributes of the C2012X5R1H684M125AB are critical for understanding its suitability for specific applications. The Applications attribute indicates “Commercial Grade,” meaning it is suitable for a wide range of general-purpose electronic devices where standard reliability and performance are required, as opposed to automotive or high-reliability military applications. The Brand, TDK, signifies a reputable manufacturer known for quality and innovation in passive components. Its Feature as “General” further emphasizes its versatility across numerous circuit designs. A Tolerance of “±20%” on its capacitance value is typical for X5R dielectric types, indicating that the actual capacitance can vary within this range from the nominal value, which is acceptable for many decoupling and bypass applications. The L x W Size of “2.0mm x 1.25mm [EIA 0805]” defines its physical dimensions, corresponding to the widely used 0805 surface-mount package, making it compatible with standard PCB layouts and automated assembly processes. The nominal Capacitance of “680nF” (nanofarads) is a substantial value for an MLCC of this size, making it effective for filtering low-frequency noise and providing local energy storage. The T(Max.) / mm of “1.45” specifies its maximum thickness, which is important for space-constrained designs. The Temp. Chara. of “X5R” is a crucial dielectric characteristic, indicating a relatively stable capacitance change over a wide operating temperature range. The Component Type is clearly identified as a “Ceramic Capacitor (MLCC),” highlighting its construction and technology. Its Product Status as “Production (NRND)” means it is currently in production but is “Not Recommended for New Designs,” suggesting that designers should consider newer alternatives for future projects while it remains available for existing ones. The Rated Voltage [DC] / V of “50V” specifies the maximum DC voltage that can be continuously applied across the capacitor without damage, making it suitable for many common low-voltage digital and analog circuits. The Cap.Change or Temp.Coef. of “±15%” over the operating temperature range is a defining characteristic of the X5R dielectric, indicating how much the capacitance can deviate from its 25°C value. Finally, the Operating Temp. Range / °C of “-55 to 85” specifies the ambient temperature limits within which the capacitor is designed to operate reliably, covering a broad spectrum of commercial and industrial environments.
