Feed through capacitors are designed to filter out AC signals in an electrical system. They are also used in power supplies, communications systems and RF circuits. The PSM4-680M-10B is a feed-through capacitor designed to provide increased filtering of unwanted signals in a power line circuit. It is a multi-layer ceramic capacitor (MLCC) with a high insulation resistance, good temperature stability and excellent resonance characteristics.

The PSM4-680M-10B is designed to provide a two-stage capacitance, with the first stage reducing common-mode noise. This is achieved through the use of a two-terminal configuration, with one terminal connected to an external power line and the other terminal connected to ground. The second stage provides a high-frequency capacitance to reduce high-frequency signals, thus providing improved performance in the circuit.

The PSM4-680M-10B is designed to operate in a wide temperature range of -25°C to +85°C, and its operating voltage range is 10V to 250V. It is designed to provide a low impedance at frequencies up to 1 GHz and excellent resonance characteristics. Its unique construction also provides a high insulation resistance to further improve filtering performance in the circuit.

The PSM4-680M-10B feed-through capacitor features a four-pole design, with the two internal terminals having a common positive pin and a common negative pin. This design makes it easier to achieve a good electrical connection to the external circuit while reducing the size of the component. In addition, the four-pole design provides a better efficiency of filtering than one- or two-pole capacitors.

In terms of working principle, the PSM4-680M-10B feed-through capacitor works by decreasing the amount of high-frequency signals passing through from one point to another. It does this by providing a barrier between the two points. The capacitor essentially works like a gate, allowing only those signals which pass through its terminals to continue through the circuit, thus blocking unwanted signals.

In applications, the PSM4-680M-10B feed-through capacitor is widely used in powerline circuits, communications systems and RF circuits for improved performance and filtering. It can be used to filter out high-frequency noise, eliminate common-mode noise and provide protection for sensitive electronic components. The capacitor is also suitable for use in audio, video and telecommunications devices, as well as for automotive and consumer electronics.

Overall, the PSM4-680M-10B feed-through capacitor is an excellent choice for applications where improved filtering is needed. Its high insulation resistance, excellent resonance characteristics and two-stage capacitance make it an excellent choice for providing improved performance in power line circuits, communications systems and RF circuits. Its small size and four-pole construction make it ideal for space restricted applications.
