Feed Through Capacitors are components that provide electrical connection between two points in a circuit by bridging from the one side to the other. The SFJEC3K00221MC1 is a type of feed-through capacitor from Murata Manufacturing Co., Ltd. that is rated for up to 3 kHz and can operates with operating temperatures ranging from -40C to +105C.

The SFJEC3K00221MC1 has a rectangular ceramic body with a metal enclosure. It measures 22.2mm x 9.4mm x 11.4mm with a max rated voltage of up to 500V. The capacitor has two separate leads that can be arranged into parallel or series as required by the application. The capacitor is typically used in audio circuitry, high frequency control circuitry, radar applications, and more.

Working Principle

The SFJEC3K00221MC1 utilizes a thin ceramic plate (dielectric) between two metal plates, typically referred to as electrodes, caps or plates. As power is applied to the capacitor, electrons jump from one plate to the other, creating an electric field. The thickness of the dielectric material determines the amount of charge stored - thinner layers create a larger capacitance. It is this capacitance that is used in the capacitor for storing energy that is released when the power is removed.

The SFJEC3K00221MC1 is designed to supply a connection between the two sides of the circuit, allowing the current to pass through. When the circuit is connected to an AC power source, the capacitor will store energy as a result of the alternating current. This stored energy is then released on the other side of the circuit as the current changes, creating an effect similar to an inductor. This allows for more stable current flow in the circuit at high frequencies.

The SFJEC3K00221MC1 is also designed to have a wide application range. It is suitable for use in high speed radi therapeutic systems, high frequency rectifier circuits, mid-frequency circuits, trigger control circuits, and many more applications. Additionally, its small size and low profile make it suitable for use in compact environments and applications where space is at a premium.
