FA26X7R2A474KNU06 FA26X7R2A474KNU06 Ceramic Capacitor (Leaded MLCC)

FA26X7R2A474KNU06 is a high-performance ceramic capacitor manufactured by TDK, a global leader in electronic components. This leaded Multi-Layer Ceramic Capacitor (MLCC) is specifically designed for demanding automotive applications, offering exceptional reliability and stability. As a passive component, its primary function is to store and release electrical energy, filter noise, and stabilize voltage in electronic circuits. The FA26X7R2A474KNU06 is part of TDK’s extensive range of robust capacitors, engineered to meet stringent industry standards and provide long-term performance in harsh environments.

Key Specifications

The FA26X7R2A474KNU06 boasts several critical specifications that underscore its suitability for advanced electronic designs. Its Capacitance of 470nF (nanofarads) indicates its ability to store a significant amount of charge, making it ideal for filtering and decoupling applications where substantial energy storage is required. The Tolerance of ±10% signifies that the actual capacitance value will be within 10% of the nominal 470nF, a common and acceptable range for many general-purpose and automotive applications. With a Rated Voltage [DC] of 100V, this capacitor can safely operate in circuits with DC voltages up to 100 volts, providing a robust margin for typical automotive 12V or 24V systems. The Temp. Chara. (Temperature Characteristic) of X7R is particularly important; X7R capacitors are known for their relatively stable capacitance over a wide temperature range, specifically from -55°C to +125°C, with a maximum capacitance change of ±15%. This stability is crucial for automotive applications where components are exposed to extreme temperature fluctuations. The physical dimensions, including L(Max.) / mm (length) of 5.5mm, W(Max.) / mm (width) of 6mm, and T(Max.) / mm (thickness) of 3.5mm, along with a F(Nom.) / mm (lead pitch) of 5mm, define its compact footprint and ensure compatibility with standard PCB layouts and automated assembly processes. The Lead Length / Package Type specified as “Taping” indicates that the component is supplied on tape, facilitating efficient automated insertion into printed circuit boards during manufacturing.

Features and Benefits
