The Brand, TDK, assures users of a product from a reputable manufacturer known for its innovation and quality in passive components. The Feature “AEC-Q200Mid150°C” indicates compliance with the Automotive Electronics Council’s AEC-Q200 standard, specifically for mid-temperature range applications up to 150°C, which is crucial for components operating in engine compartments or other high-temperature environments. The explicit “YES” for AEC-Q200 further confirms this automotive qualification. A Tolerance of “±5%” denotes a high degree of precision in the capacitance value, which is vital for applications requiring accurate timing or filtering. The L x W Size of “2.0mm x 1.25mm [EIA 0805]” describes the physical dimensions of the component, corresponding to the industry-standard 0805 package, facilitating easy integration into compact PCB designs. The Capacitance of “8.2nF” (8.2 nanofarads) is the component’s primary electrical storage capacity. T(Max.) / mm at “1.45” refers to the maximum thickness of the component, an important consideration for space-constrained designs. The Temp. Chara. of “NP0” (also known as C0G) indicates a highly stable dielectric material with negligible capacitance change over a wide temperature range, making it suitable for precision applications. The Component Type is clearly a “Ceramic Capacitor (MLCC),” specifying its construction and technology. Its Product Status as “Production” confirms that it is an actively manufactured and readily available part. The Rated Voltage [DC] / V of “100” specifies the maximum DC voltage the capacitor can safely withstand. Cap.Change or Temp.Coef. of “0±30ppm/°C” is a critical parameter for NP0 dielectrics, indicating an extremely low temperature coefficient of capacitance, meaning its value remains very stable across temperature variations. Finally, the Operating Temp. Range / °C of “-55 to 150” highlights its robust performance across a broad spectrum of temperatures, essential for automotive and industrial environments.
