Key Specifications

The attributes of the FK28X5R0J685KR000 are carefully selected to provide optimal performance. The Applications are specified as “Commercial Grade,” indicating its suitability for a broad spectrum of general-purpose electronic devices, from consumer electronics to industrial control systems, where robust performance is required without the extreme demands of automotive or medical applications. The Brand, TDK, signifies a heritage of innovation and quality in the electronics industry. The Feature is “General,” highlighting its versatility for standard decoupling, filtering, and timing applications. A Tolerance of “±10%” on its capacitance value means the actual capacitance will be within 10% of the nominal value, which is a common and acceptable range for many commercial applications, ensuring circuit stability. The Capacitance of “6.8µF” (microfarads) denotes its ability to store a significant amount of charge, making it suitable for applications requiring substantial energy storage or filtering. The physical dimensions, F(Nom.) / mm: 5, L(Max.) / mm: 4, T(Max.) / mm: 2.5, and W(Max.) / mm: 5.5, describe the nominal lead spacing, maximum length, thickness, and width respectively, which are crucial for PCB layout and mechanical fit. The Temperature Characteristic, “X5R,” indicates that the capacitance change is within ±15% over an operating temperature range of -55°C to +85°C, making it suitable for environments with moderate temperature fluctuations. The Component Type is clearly defined as a “Ceramic Capacitor (Leaded MLCC),” specifying its construction and leaded form factor for through-hole mounting. Its Product Status is “Production (NRND – Not Recommended for New Designs),” meaning it is currently in production but may be phased out, suggesting it’s best for existing designs or replacements. The Rated Voltage [DC] / V of “6.3V” specifies the maximum DC voltage that can be continuously applied across the capacitor without risk of breakdown, which is typical for low-voltage digital and analog circuits. Finally, the Lead Length / Package Type is “7mm for Bulk,” indicating that the leads are 7mm long and supplied in bulk packaging, suitable for manual or automated insertion processes.
