940C10P68K-F

Film capacitors are an indispensable component in modern day electronics. They are used in a variety of power supply and signal applications, ranging from laptops and cellphones to medical and industrial equipment. The 940C10P68K-F is a film capacitor manufactured and sold by TDK, a well known electronics parts supplier. This article discusses the application field and working principle of the 940C10P68K-F.

Application Field

The 940C10P68K-F film capacitor is a small size capacitor with a typical capacitance above 10μF. It has rated voltage of 10VAC and peak voltage of up to 16.5VAC. Due to its relatively low capacitance, it is suitable for use in low voltage power supply circuits such as laptop AC power adapters and small power circuits of cell phones. It is also used as the AC filter in industrial equipment to stabilize the power supply, reduce noise and smooth out any current fluctuations.

Working Principle

The working principle of the 940C10P68K-F film capacitor is based on the same electrostatic principles as other capacitors. It is constructed from two layers of metallized insulating material – usually polyethylene terephthalate film – with a dielectric in between. This film is rolled up tightly with alternating layers of metal deposited on it. When a voltage is applied across the capacitor, an electric field is generated, which causes the metal layers to form opposite electric charges, effectively creating a potential difference across the device. The result is a tiny capacitor capable of handling AC power with a relatively low voltage rating.

The 940C10P68K-F film capacitor is an ideal choice for many different applications due to its low capacitance and robust construction. It is an indispensable component in modern electronics due to its low loss, long life and stable performance.
