Feed through capacitors are a type of capacitor designed to allow a signal to pass unhindered through a circuit while rejecting any unwanted frequencies. At the same time, they allow frequencies within a desired range to be filtered in or out of the signal chain. This makes them ideal for signal conditioning, power conditioning, and general signal protection applications. The 4300-025LF is an example of a feed-through capacitor that is designed to meet MIL-STD-1344 and IEC standard 61000-4 requirements.

The 4300-025LF capacitors are constructed with multilayered dielectrics, which allows them to reject unwanted frequencies while passing the ones that are needed. They are offered in a variety of voltage ratings, from 2.5 volts to 250 volts, and have a long-term stability of up to five years. The combination of low voltage and long-term stability makes the 4300-025LF capacitors ideal for a wide range of applications including high-voltage power distribution, noise suppression, medical devices, and aerospace. Additionally, the 4300-025LF is designed with a low temperature coefficient, which ensures that its performance remains consistent over time.

The 4300-025LF employs a unique working principle, which allows it to serve both as a filter capacitor and as a high-voltage conductor. The filter capacitor is responsible for blocking unwanted frequencies, while the high-voltage conductor carries the desired signal across its rated voltage range. The conductor is composed of a pair of non-conductive layers that form the capacitor’s connections. This allows it to act as both a conductor and a filter simultaneously. This principle is also beneficial for high-voltage power distribution applications, since it can protect the system from undesirable frequencies without affecting the desired power flow.

The 4300-025LF is also designed with a double-cap PCB design, which helps to reduce the overall size and cost of the capacitor. This technology is also beneficial for reducing inductance, which can cause interference with the desired signal and cause undesired reactions within the system. With the double-cap design, the inductance of the capacitor is reduced and the signal is better protected.

Overall, the 4300-025LF is a great choice for feed-through capacitors, as it offers a number of key benefits. With its low-temperature coefficient and long-term stability, it is ideal for a variety of power and noise suppression applications. Additionally, its unique working principle, featuring both a filter capacitor and a high-voltage conductor, allows it to protect the system from undesirable frequencies without sacrificing the desired signal. Finally, its double-cap PCB design helps reduce the size and cost of the overall capacitor. The 4300-025LF is certainly an excellent choice for feed-through capacitors.
