Key Specifications

The attributes of the FK28C0G2E121JN000 ceramic capacitor are meticulously engineered to meet demanding commercial requirements. The Applications attribute specifies “Commercial Grade,” indicating its suitability for a broad range of general-purpose and non-automotive industrial electronics, where high reliability is important but not mission-critical like automotive or medical life-support systems. The Brand, TDK, signifies a commitment to quality and innovation, ensuring that engineers receive a component from a reputable manufacturer. The Feature is categorized as “Mid,” suggesting a balance of performance and cost-effectiveness for a wide array of designs. A tight Tolerance of “±5%” for capacitance is crucial for applications requiring precise timing, filtering, or resonant circuits, ensuring that the actual capacitance value deviates minimally from the nominal 120pF. The Capacitance of “120pF” is a common value used in high-frequency circuits, coupling, decoupling, and resonant tank circuits. The physical dimensions, including F(Nom.) / mm (5mm), L(Max.) / mm (4mm), T(Max.) / mm (2.5mm), and W(Max.) / mm (5.5mm), define the footprint and form factor, which are critical for PCB layout and mechanical integration. The Temp. Chara. of “C0G” is a highly stable dielectric, meaning its capacitance changes negligibly with temperature, making it ideal for precision applications. The Component Type is explicitly a “Ceramic Capacitor (Leaded MLCC),” highlighting its construction and through-hole mounting capability. The Product Status is “Production(NRND)” (Not Recommended for New Designs), which implies it is still in production but may be superseded by newer alternatives, though still available for existing designs. The Rated Voltage [DC] / V of “250V” indicates the maximum DC voltage it can withstand continuously without breakdown, providing a significant margin for many common circuit voltages. Finally, the Lead Length / Package Type of “7mm for Bulk” specifies the lead length for through-hole mounting, suitable for manual or automated insertion in bulk packaging.
