Additional Details

The CF42 case size refers to the physical dimensions of the capacitor. The 'CG' temperature characteristic indicates that the capacitance changes very little with temperature, typically within ±30 parts per million per degree Celsius. This stability is crucial in applications where consistent performance is required regardless of temperature fluctuations. The high voltage rating allows it to be used in applications with voltage spikes or high steady-state voltages without risk of failure. These capacitors are manufactured using a precise layering process to achieve consistent electrical characteristics and are subjected to rigorous testing to ensure reliability.

The part number CF42CG150J3000AT breaks down as follows: CF42 likely refers to the case size, CG indicates the temperature coefficient, 150 signifies 15 pF (15 x 10^0 pF), J represents the tolerance (±5%), and 3000AT indicates 3000V voltage rating and termination type.
