Feed Through Capacitors

A feed through capacitor, also known as a capacitor feed-thru or capacitor filter, is an electrical component used to attenuate voltage drops on power lines and to reduce electromagnetic interference in electronic circuits. This type of capacitor provides electrical isolation between two or more conductor paths and acts as a reservoir of electrical charge. As electric and magnetic fields build up around the component, the electrical charges stored in the capacitor dissipate, thus keeping the power on the conductive path free of interference.

YFF21SC1H222MT009N is one of the types of feed through capacitors available in the market. It is a power capacitor designed for use in high frequency applications with a very low impedance and temperature rise. The capacitor features a polypropylene dielectric and a high dielectric coating, and is rated for an operating temperature range of -50 to +85 Celsius. The capacitor has a capacitance of 2.2μF and a maximum working voltage of 250VAC.

Application Field

The YFF21SC1H222MT009N is designed for various high frequency applications where a low impedance and temperature rise are desired. These capacitors are typically used in power supplies, motor applications, induction motors, electric motors, lighting systems, home automation, industrial control systems, HVAC, and various other applications. In addition, these capacitors provide excellent noise attenuation and EMI/RFI reduction in sensitive electronic components.

Working Principle

The YFF21SC1H222MT009N feed through capacitor consists of a dielectric material placed between two conducting electrodes. When a voltage is applied across the electrodes, an electric field is generated in the dielectric material. This electric field stores electrical energy, which is proportional to the applied voltage. When the voltage is removed, the stored energy is discharged from the capacitor, attenuating the voltage on the conductive path.

In addition, the YFF21SC1H222MT009N features a high ESR rating, which helps to reduce unintentional current leakage through the capacitor. This is especially important in applications that require very low gain and low current leakage. The capacitor\'s capacitance also helps to reduce electrical noise and EMI, allowing sensitive electronic components to work without being disturbed by external interference.

The YFF21SC1H222MT009N feed through capacitor provides excellent protection against voltage drops, current leakage, EMI, and RFI, providing increased system efficiency and improved reliability. It is an ideal choice for a variety of high frequency applications where a low impedance and temperature rise are desired.
