The ECQ-E6223KF is a set of film capacitors by Panasonic with a 630V DC working voltage, a capacity of 0.022uF, and a tolerance of 10 percent. The lead spacing is 12.5mm, and it is designed for applications with high-frequency signals requiring low-noise performance. This capacitor has very low ESL and self-resonance frequencies, making it well-suited for high-frequency operations. Additionally, it has very low physical size and weight compared to other capacitors of the same class. The ECQ-E6223KF is most suitable for audio filtering, power supply filters, and decoupling applications.
