FK28X5R0J475KR000 is a high-quality, leaded multilayer ceramic capacitor (MLCC) manufactured by TDK, a global leader in electronic components. This passive component is specifically designed to store and release electrical energy, filter noise, and stabilize voltage in a wide array of electronic circuits. As a ceramic capacitor, it utilizes a ceramic dielectric material, offering excellent frequency characteristics and reliability, making it a cornerstone component in modern electronics. The leaded format ensures robust mechanical connection and ease of integration into through-hole PCB designs, catering to applications where mechanical stability and manual assembly or repair might be preferred over surface-mount technology.

Key Specifications

The FK28X5R0J475KR000 boasts several critical specifications that define its performance and suitability for various applications. Its Capacitance of 4.7μF (microfarads) indicates its ability to store a significant amount of electrical charge, making it suitable for filtering, coupling, and bypass applications where larger capacitance values are beneficial. The Tolerance of ±10% signifies that the actual capacitance value will be within 10% of 4.7μF, which is a standard and acceptable range for many commercial and industrial applications, ensuring consistent circuit performance. The Rated Voltage [DC] of 6.3V specifies the maximum DC voltage that can be continuously applied across the capacitor without risk of breakdown, making it ideal for low-voltage power supplies and signal processing circuits. The Temp. Chara., X5R, is a crucial attribute indicating its temperature stability. X5R capacitors are known for their capacitance change being within ±15% over an operating temperature range of -55°C to +85°C, making them suitable for general-purpose applications that experience moderate temperature variations. The Apps. attribute, ‘Commercial Grade,’ confirms its design for use in standard commercial electronic products, balancing performance with cost-effectiveness. The physical dimensions, L(Max.) / mm (4mm), W(Max.) / mm (5.5mm), and T(Max.) / mm (2.5mm), along with a nominal lead spacing F(Nom.) / mm of 5mm, provide essential information for PCB layout and mechanical integration. The Lead Length / Package Type is specified as ‘7mm for Bulk,’ indicating that these components are supplied with leads trimmed to 7mm, suitable for automated insertion or manual assembly processes from bulk packaging.
