YFF21SC1H473MT009N belongs to a type of feed-through capacitors, which are capacitors designed for AC or radio frequency line filtering in applications. Feed-through capacitors are highly recommended for use in power lines, signal lines, and other electrical installation processes.The YFF21SC1H473MT009N feed-through capacitor features a flat capacitance, a frequency range of 10 kHz to 100 MHz, a current rating of 5 Amp (RMS) and a voltage rating of 450 AC/DC. This capacitor also features a low inductance, significantly reducing any unwanted interference from the filtering process. The capacitance of this type of capacitor is typically large enough to filter out line noise and other interference signals, ensuring a clean power supply.The YFF21SC1H473MT009N feed-through capacitor is constructed of a metalized polypropylene dielectric film, which is then coated with an epoxy material to prevent electrical and temperature disasters. This design also helps to achieve a consistent electrical performance, including effective capacitance. The capacitor also features a long operating life and low self-heating temperature which make it suitable for high temperature applications.The working principle of the feed-through capacitor is based on the electrostatic principle. Electrons are attracted and repelled between the two electrodes. Each electrode is connected to a capacitor plate, and a dielectric material is applied between them. When an AC/DC signal travels through the capacitor, it will be passed through the capacitor plates and be filtered by the dielectric material. The filtered signal is then collected by the other end, resulting in an output with reduced interference and unwanted noise.The feed-through capacitor is widely used in telecommunications, computers, circuit boards, motors, motors control devices, consumer electronics, and other electrical applications. In these applications, the filter design is used to reduce noise pollution, improve power quality, and increase system reliability. This type of capacitor is also used in HVAC and lighting control systems to reduce line noise from other system components, such as fans and pumps.Overall, the YFF21SC1H473MT009N feed-through capacitor is a popular and efficient component for AC/DC and RF noise filtering. Its high capacitance rating makes it suitable for line noise reduction and other applications which depend on having consistent, clean power. Its excellent construction and working principle contribute to its long operating life and high performance, making it an ideal choice for telecom and consumer electronics systems.
