Feedthrough capacitors are uniquely designed capacitors widely used for AC/DC supply lines to reduce harmful interference required for filtering circuits. They are the perfect capacitors compared to common capacitors, which result in higher impedance. Furthermore, these high-current capacitors are ideal for high-power applications such as data lines, AC power lines, telecommunications equipment, industrial computers, and composite circuit filter components. Special caution is essential as these capacitors are generally connected to high-energy circuits or high voltage.
Types of feedthrough capacitors:
There are various types of these capacitors, such as:
-
Surface Mount feedthrough capacitors:
Surface feedthrough filters provide an effective way to achieve broadband EMI reduction in a mini surface-mounted package. These capacitors increase the system reliability and save the PCB area by reducing the cost of designs by eliminating some L/C filters. In addition, they come in various element packages.
-
Plastic Film Feedthrough capacitors:
These capacitors are primarily used in applications with high-reliability component demands and are extensively employed in circuits where high insulation resistance and low loss are required.
-
Discoidal feedthrough capacitors:
They are widely used in EMI filters and are available in varied designs with various capacitance ranges.
-
Tubular ceramic feedthrough capacitors:
These capacitors feature a unique structure yielding outstanding low inductance and are widely employed in high-frequency applications.
Applications of Feedthrough Capacitors:
These capacitors are found in a wide range of applications and circuits, such as:
- Electronic Circuits (EMI/RFI suppression circuits, power converters)
- Telephone Exchanges
- Microwave
- Power supplies (AC/DC)
