FA26X7R1H684KNU06 FA26X7R1H684KNU06 Ceramic Capacitor (Leaded MLCC)

FA26X7R1H684KNU06 is a high-performance ceramic capacitor (Leaded MLCC) manufactured by TDK, a global leader in electronic components. This specific model is designed for demanding applications, particularly within the automotive sector, thanks to its AEC-Q200 qualification. As a passive component, its primary function is to store and release electrical energy, filter noise, and stabilize voltage in electronic circuits. The leaded format ensures robust mechanical attachment and ease of through-hole assembly, making it suitable for a wide range of industrial and automotive electronics where reliability and longevity are paramount.

Key Specifications

The FA26X7R1H684KNU06 boasts several critical specifications that define its performance and suitability for various applications. Its Capacitance of 680nF (nanofarads) indicates its ability to store a significant amount of charge, making it effective for decoupling, filtering, and timing circuits. The Tolerance of ±10% signifies that the actual capacitance value will be within 10% of the nominal 680nF, a standard range for many general-purpose and automotive applications, ensuring consistent circuit performance. The Rated Voltage [DC] of 50V specifies the maximum DC voltage that can be continuously applied across the capacitor without breakdown, making it suitable for common 12V and 24V automotive systems, as well as various industrial control circuits. The Temperature Characteristic, X7R, is crucial; it denotes a dielectric material that provides a relatively stable capacitance over a wide temperature range, typically from -55°C to +125°C, with a maximum capacitance change of ±15%. This stability is vital for applications exposed to varying environmental conditions. The physical dimensions, including L(Max.) / mm of 5.5mm, W(Max.) / mm of 6mm, and T(Max.) / mm of 3.5mm, define the maximum length, width, and thickness of the component, which are important for PCB layout and mechanical integration. The F(Nom.) / mm of 5mm refers to the nominal lead spacing, critical for automated insertion and board design. The Lead Length / Package Type being ‘Taping’ indicates that the components are supplied on tape and reel, facilitating automated assembly processes in manufacturing environments.
