The Brand, TDK, is synonymous with high-quality electronic components, providing assurance of reliability and performance. The Feature “AEC-Q200 150°C Glue” highlights its compliance with the AEC-Q200 standard and its capability to operate at temperatures up to 150°C, further reinforced by the explicit AEC-Q200 attribute being “YES.” The “Glue” aspect often refers to the termination material or internal construction designed for enhanced robustness. A Tolerance of “±20%” indicates the permissible deviation of the actual capacitance value from the nominal 4.7nF, which is a common and acceptable range for many filtering and coupling applications. The L x W Size of “1.6mm x 0.8mm [EIA 0603]” specifies its compact dimensions, making it suitable for miniaturized circuits where space is a premium. The Capacitance of “4.7nF” (nanofarads) is the core electrical property, defining its energy storage capability. T(Max.) / mm at “0.95” refers to the maximum thickness of the component, critical for PCB layout and clearance considerations. The Temp. Chara. of “X8R” is a crucial dielectric characteristic, indicating that the capacitance change over the specified operating temperature range is within ±15%. This is confirmed by the Cap.Change or Temp.Coef. attribute of “±15%,” signifying excellent temperature stability for automotive applications. The Component Type, “Ceramic Capacitor (MLCC),” confirms its construction as a multi-layer ceramic capacitor. The Product Status is “Production,” meaning it is an actively manufactured and readily available part. The Rated Voltage [DC] / V of “50” specifies the maximum DC voltage that can be continuously applied across the capacitor without risk of breakdown. Finally, the Operating Temp. Range / °C of “-55 to 150” defines the broad temperature spectrum over which the capacitor can reliably function, a critical parameter for automotive environments.
