Key Specifications

The C2012X7R2A473K125AE capacitor boasts several critical specifications that define its performance and suitability for diverse applications. Its ‘Apps.’ attribute as ‘Commercial Grade’ indicates its design for general-purpose electronic devices, ensuring a balance of performance and cost-effectiveness. The ‘Brand’ is TDK, synonymous with reliability and advanced ceramic technology in the electronics industry. The ‘Feature’ of ‘MidSoft’ refers to the capacitor’s termination, which provides enhanced resistance to thermal and mechanical stresses, improving overall reliability. A ‘Tolerance’ of ‘±10%’ for capacitance means that the actual capacitance value will be within 10% of the nominal 47nF, which is a standard tolerance for many commercial applications. The ‘L x W Size’ of ‘2.0mm x 1.25mm [EIA 0805]’ specifies its physical dimensions, corresponding to the widely recognized 0805 EIA standard, allowing for compact circuit board designs. The ‘Capacitance’ of ’47nF’ (nanofarads) is the core electrical storage capacity of the component. ‘T(Max.) / mm’ at ‘1.5’ denotes the maximum thickness of the component, crucial for height-constrained designs. The ‘Temp. Chara.’ of ‘X7R’ is a critical attribute, indicating that the capacitance change is within ‘±15%’ over an ‘Operating Temp. Range / °C’ of ‘-55 to 125’. X7R dielectric material is known for its relatively stable capacitance over a wide temperature range, making it suitable for applications where temperature variations are expected. The ‘Component Type’ is clearly identified as a ‘Ceramic Capacitor (MLCC)’, highlighting its construction and technology. Its ‘Product Status’ as ‘Production’ confirms that it is an actively manufactured and readily available part. Finally, a ‘Rated Voltage [DC] / V’ of ‘100’ specifies the maximum DC voltage that can be continuously applied across the capacitor without breakdown, ensuring safety and longevity in 100V systems.

Features and Benefits

• Versatile Commercial Grade: Designed for commercial applications, it provides a cost-effective yet reliable solution for a wide array of general-purpose electronic circuits, balancing performance and economic considerations.
• 100V DC Rating: A robust 100V DC rated voltage makes it suitable for applications requiring higher voltage handling capabilities, offering a margin of safety and broader applicability.

Typical Applications

The TDK C2012X7R2A473K125AE MLCC finds extensive use across numerous electronic applications due to its stable characteristics and compact size. One common application is in DC-DC converters, where it functions as an input or output filter capacitor to smooth voltage ripples and stabilize the power supply, ensuring clean power delivery to sensitive components. Another significant use case is in general-purpose decoupling for integrated circuits (ICs). By placing this capacitor close to the power pins of an IC, it provides a local reservoir of charge, rapidly supplying current spikes and shunting high-frequency noise to ground, thereby improving the IC’s operational stability and reducing electromagnetic interference (EMI). Furthermore, it is frequently employed in timing circuits and oscillators, where its stable capacitance contributes to the accuracy and reliability of frequency generation. In LED lighting drivers, these capacitors are used for filtering and energy storage, helping to maintain a consistent current flow to the LEDs and improving overall efficiency and flicker reduction. Lastly, its commercial-grade nature makes it ideal for various consumer electronics such as smartphones, tablets, and home appliances, where space is at a premium and reliable performance is essential for user satisfaction.

In summary, the C2012X7R2A473K125AE from TDK is a robust and versatile ceramic capacitor, offering excellent performance characteristics for a wide range of commercial applications. Its stable X7R dielectric, compact 0805 size, and 100V rating make it an indispensable component for modern electronic designs.
