C1608X8R1H472M080AA C1608X8R1H472M080AA Ceramic Capacitor (MLCC)

C1608X8R1H472M080AA is a high-performance multilayer ceramic capacitor (MLCC) manufactured by TDK, a global leader in electronic components. This passive component is designed for surface mount applications and plays a crucial role in various electronic circuits by storing and releasing electrical energy, filtering noise, and stabilizing voltage. Its robust construction and advanced dielectric material make it suitable for demanding commercial-grade applications, particularly where high operating temperatures are a concern.

Key Specifications

The Capacitance of 4.7nF (nanofarads) indicates the component’s ability to store charge. This specific value is commonly used in a wide range of filtering, coupling, and decoupling applications in digital and analog circuits. The Tolerance of ±20% means the actual capacitance can vary by up to 20% from the nominal 4.7nF, which is typical for general-purpose ceramic capacitors and acceptable for many non-precision applications. The Rated Voltage [DC] / V is 50V, signifying the maximum DC voltage that can be continuously applied across the capacitor without risk of breakdown. This rating is important for ensuring reliability and preventing component failure in circuits with varying voltage levels. The L x W Size is 1.6mm x 0.8mm, corresponding to the EIA 0603 standard package. This miniature size is highly advantageous for space-constrained designs, enabling compact and high-density PCB layouts. The Temp. Chara. is X8R, which defines the capacitor’s temperature coefficient and capacitance change over its operating temperature range. X8R dielectrics are known for their stable capacitance performance up to 150°C. The Cap.Change or Temp.Coef. of ±15% over the full operating temperature range of -55 to 150°C confirms the X8R characteristic, indicating that the capacitance will not deviate by more than 15% from its 25°C value within this wide temperature span. The maximum thickness T(Max.) / mm is 0.9mm, providing critical information for mechanical design and clearance considerations on a PCB. The Operating Temp. Range / °C is -55 to 150°C, highlighting its suitability for extreme temperature environments, far exceeding the typical 85°C or 125°C limits of many standard capacitors. This extended range is a key differentiator for the C1608X8R1H472M080AA.
