Its capacitance stability is excellent, even in harsh temperature environments, and the working temperature range is -40°C to +105°C.

Typical Application of the DMM6P22K-F

The DMM6P22K-F capacitors are commonly used in low voltage applications for power factor correction, signal filtering, and motor soft start. In microelectronics, they have applications in inductor applications, resonators, compensation circuits, filtering circuits, and RF circuits.

Working Principle of the DMM6P22K-F

The DMM6P22K-F capacitor works according to the principle of Faraday’s law of induction. A current is applied to a conductive plate on one side of the capacitor, while the other plate remains stationary. This produces an electric field between the two plates, with electrons having a lower potential energy being attracted towards the plate with the higher potential energy. This electric field increases as the plates become closer together, and the capacitance increases accordingly.

The dielectric of the DMM6P22K-F offers superior insulation, and can hold much higher potential between the plates due to the low dielectric constant of the polypropylene. The produced electric field can store more energy that can later be released when the current is switched off or dissipated in current flowing through the capacitor.

The capacitance of the DMM6P22K-F is not affected by time or temperature, and therefore its performance is consistent. Additionally, its sturdy construction and its resistance to thermal shock make it suitable for use in harsh environments.
