Key Specifications

The attributes of the FK28C0G2E121JN006 capacitor are critical for understanding its performance and suitability for specific designs. The ‘Apps.’ attribute indicates its ‘Commercial Grade’ nature, meaning it is designed for general-purpose applications where standard reliability and performance are required, distinct from automotive or high-reliability military specifications. The ‘Brand’ is ‘TDK’, assuring quality and adherence to stringent manufacturing standards from a reputable Japanese electronics company. The ‘Feature’ is classified as ‘Mid’, suggesting a balance between performance and cost-effectiveness, suitable for a broad spectrum of circuit designs. A ‘Tolerance’ of ‘±5%’ on its capacitance value of ‘120pF’ signifies a precise component, ensuring that the actual capacitance will be very close to the nominal value, which is crucial for frequency-sensitive circuits and timing applications. The physical dimensions are specified as ‘L(Max.) / mm: 4’, ‘W(Max.) / mm: 5.5’, and ‘T(Max.) / mm: 2.5’, providing engineers with the necessary data for PCB layout and mechanical integration. The ‘F(Nom.) / mm: 5’ likely refers to the nominal lead spacing, important for automated insertion and board compatibility. The ‘Temp. Chara.’ is ‘C0G’, which is a highly stable dielectric material known for its negligible change in capacitance over a wide temperature range (-55°C to +125°C) and excellent low-loss characteristics, making it ideal for resonant circuits and precision timing. The ‘Rated Voltage [DC] / V’ is ‘250’, indicating its maximum permissible DC operating voltage, a critical parameter for power supply and high-voltage applications. Finally, the ‘Lead Length / Package Type’ is ‘Taping’, meaning the components are supplied on tape for automated pick-and-place assembly, streamlining manufacturing processes.
