Feedthrough Capacitors

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)
