Feed Through Capacitors

Feed through capacitors, also known as electrical bypass capacitors, are components typically used in high frequency circuit applications to reduce radio frequency interference or "noise". They are commonly found in power supplies, radio transmitters, and certain electronic components that require high accuracy and low noise performance. The W3F15C4728AT1F is one such type of feed through capacitor.The purpose of a feed through capacitor is to short the electromagnetic fields that can cause interference and/or damage to sensitive electrical equipment. In essence, they act as a filtering mechanism which reduces noise and provides a more uniform and balanced signal. The feed through capacitor does this by redirecting the current in an alternating fashion, creating a more uniform field of charge which then travels to the desired destination.The W3F15C4728AT1F is a feed through capacitor with a capacitance of 50 pF and a maximum voltage of 15 VDC. It has a high linear capacitance and low dissipation factor, which is important for applications that require a high frequency circuit. It is suitable for use in environments such as telecommunications and data transmission networks, as well as for switching power supplies, and other high frequency circuit applications.The W3F15C4728AT1F uses a single-pole parallel-plate capacitor configuration. Its wide frequency range of DC to 500 MHz and robustness under harshest conditions make it suitable for a broad range of applications. It is also well suited for high voltage applications, as it is able to handle up to 15 VDC. The W3F15C4728AT1F feed through capacitor is also designed with an uncovered contact layer that can dissipate heat quickly, thus ensuring improved performance and long-term reliability.The working principle behind a feed through capacitor is relatively simple; when an alternating current is passed through the capacitor, the current alternates between the two plates creating a charging and discharging effect. This alternating current causes the electric field between the two plates to decrease in magnitude from its initial level and as it continues to oscillate, the electric field gradually approaches zero. This mechanism results in the reduction of interfering noise being added to the signal and the improvement in signal quality.In summary, the W3F15C4728AT1F is a feed through capacitor suitable for use in a wide range of applications, typically in high frequency circuits. Its single-pole parallel-plate capacitor configuration is responsible for its wide frequency range and high linear capacitance. Its robustness under harshest conditions make it suitable for harsh environments, while its uncovered contact layer aids in quick heat dissipation, ensuring consistent performance and reliability. The feed through capacitor works by reducing noise in an alternating current, resulting in improved signal quality.
