Film capacitors are an incredibly versatile component, capable of operating in extreme temperatures, high vibration environments, extreme current loads, and have long life spans compared to other types of capacitors. The 947D221K122AEGSN film capacitor is an example of such an ultimate performance class of capacitor developed for applications where there is a need for high accuracy, stability, and precision.

The 947D221K122AEGSN Capacitor is a polypropylene film and foil capacitor, featuring high current capability for use in switch mode power supplies, inverters, high frequency EMI filter designs, and resonant circuit applications. Due to its design and features, the 947D221K122AEGSN Capacitor can be used in the most extreme applications, such as those found in defense, aerospace, and industrial control systems.

The first key feature of the 947D221K122AEGSN Capacitor is its high capacitance. The capacitance value of the 947D221K122AEGSN capacitor ranges from 0.22nF to 0.10uF, providing high capacitance for higher frequency applications. The self-healing failure of the polypropylene film and foil, which is self-healing due to a low-temperature solid-state reaction of the cathode and anode films, ensures the robustness of this capacitor, even under extreme conditions.

The self-healing phenomenon provides fast response, high stability and low ESR (Equivalent Series Resistance). As a result, these capacitors can work at much higher frequencies up to 1,000kHz and allow for higher current peaks with lower ESR values, which is advantageous in SMPS (Switch-Mode Power Supplies) applications. Furthermore, due to their high operating temperature of up to 105°C and low dissipation factor, thes 947D221K122AEGSN capacitors offer excellent long term stability in extreme temperature environments.

The second key feature, which makes the 947D221K122AEGSN capacitor so versatile, is its low loss and high voltage specification. The low loss characteristic of the 947D221K122AEGSN capacitor allows it to perform well in high frequency, high EMI filter designs, and in resonant circuit applications. Additionally, this capacitor can withstand very high voltages without any breakdown. An insulation resistance value greater than 1x1012 ohms for a minimum voltage of 250V makes this capacitor ideal for AC/DC switching or isolating circuits.

Finally, the 947D221K122AEGSN capacitor has excellent long-term life and reliability due to its combination of a low dissipation factor and high current capability. This combination ensures a highly reliable product and long service life-span in demanding applications.

In conclusion, the 947D221K122AEGSN Capacitor combines excellent features suitable for extreme environments with long-term reliability. This exemplary polypropylene film and foil capacitor provides high capacitance and high voltage operations, allowing for applications where accuracy, stability, and precision are of paramount importance.
