Key Specifications

The Apps. attribute, ‘High Reliability Grade’, signifies that this capacitor is engineered for critical applications where failure is not an option. This often includes automotive, industrial, and medical electronics where consistent performance over extended periods and under harsh conditions is required. The Brand, TDK, assures quality and adherence to stringent manufacturing standards, as TDK is renowned for its innovative and dependable passive components. The Feature ‘AEC-Q200Mid’ and the explicit ‘AEC-Q200: YES’ indicate that this capacitor meets the Automotive Electronics Council’s rigorous qualification standards for passive components, making it suitable for automotive applications. The Tolerance of ‘±10%’ specifies the permissible deviation from the nominal capacitance value, ensuring that the component performs within acceptable parameters for circuit design. The L x W Size of ‘1.6mm x 0.8mm [EIA 0603]’ denotes a standard surface-mount package, enabling automated assembly and integration into compact designs. The Capacitance of ‘1nF’ (1 nanofarad) is a common value used for high-frequency filtering and signal coupling. The T(Max.) / mm of ‘0.9’ refers to the maximum thickness of the component, important for clearance and stacking considerations in PCB design. The Temp. Chara. ‘X7R’ signifies a dielectric material that provides relatively stable capacitance over a wide temperature range, with a Cap.Change or Temp.Coef. of ‘±15%’ across the full operating temperature range. The Component Type ‘Ceramic Capacitor (MLCC)’ clearly identifies its construction and fundamental electrical properties. The Product Status ‘Obsolete’ indicates that while the part may still be available through distributors, it is no longer actively manufactured by TDK, which is an important consideration for long-term design and procurement. The Rated Voltage [DC] / V of ‘100’ 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 125’ highlights its ability to function reliably in extreme thermal environments, reinforcing its high-reliability grade.
