Feed-through capacitors are widely used in various industries. The 4300-681LF is an example of a feed-through capacitor developed by Motorola. This component is used in board-level AC power filtering, and has a low-inductance that makes it ideal for high-speed data processing applications.

The 4300-681LF is an axial-lead component with a silver-plated brass end cap. The lead-frame is a multi-lug configuration formed from tin-plated copper. The inner components consist of 14 0.01µF monolithic ceramic capacitors connected in series for a total capacitance of 0.14µF. The axial leads are sealed with a special epoxy which provides a moisture-proof seal. The 4300-681LF is rated at 400 volts AC and 5 amps maximum current.

The primary application field of the 4300-681LF is in the area of board-level AC power filtering. It is used to provide filtered power to circuits such as high-speed data processors and switching power supplies. The device works by blocking any high frequency components that cause power supply noise and instability. The 4300-681LF also reduces the amount of current required to operate the circuit, providing improved efficiency and reliability.

The working principle of the 4300-681LF is based on the concept of impedance. The device is designed in such a way that the total capacitance of the component (0.14µF) is much larger than the impedance of the power line, thus creating a high-pass filter effect. This drastically reduces the amount of high-frequency noise which can affect the performance of circuits and components.

In summary, the 4300-681LF is an axial-lead feed-through capacitor developed by Motorola. It is used in board-level AC power filtering, and has a low-inductance that makes it ideal for high-speed data processing applications. The device blocks high frequency components that can otherwise cause noise and instability in the power supply, while also providing improved efficiency and reliability.
