Mica and PTFE capacitors are among the most popular types of capacitors. This is because they offer considerable advantages over other capacitors in terms of performance, reliability, size, and cost. Most mica and PTFE capacitors have a metalized or layered structure that consists of an insulating layer, typically of mica or PTFE, sandwiched between two metallic layers. This construction allows for high capacitance values and reduced losses in energy charge/discharge.

The CD5EC430GO3F is a mica and PTFE capacitor developed by Cornell Dubilier Electronics, and it is designed to provide industry-leading features and performance. This capacitor is a Category B capacitor, which is a mica capacitor rated at 25 KV. The CD5EC430GO3F is suitable for use in capacitor-coupled RF circuits operating up to 30 MHz (see figure 1).

The CD5EC430GO3F provides good high-frequency performance, stability over temperature, high insulation resistance, and low mass. The capacitor is constructed using a unique mica/PTFE sandwich technology, which provides excellent insulation properties, good outside air resistance, and RF performance. This type of construction also allows the capacitor to provide long-term stability, low inductance, and high capacitance. The improved performance of the CD5EC430GO3F is verified through tests conducted at Cornell Dubilier Electronics.

The working principle of the CD5EC430GO3F is the same as any other capacitor. When a positive voltage is applied across the capacitor, the electrons are attracted to the positive plate, strengthening the electrostatic field between the plates (figure 2). This causes the voltage on the capacitor to increase until the positive charge on one plates is equal to the negative charge on the other. At this point, no more current can flow between the plates and the capacitor is said to be fully charged.

The CD5EC430GO3F is commonly used in a variety of applications, such as filters, coupling circuits, and other RF circuits. The capacitor can also be used in decoupling circuits, or when their high insulation resistance, low inductance, and small size are desired. Additionally, the CD5EC430GO3F is often used in high-voltage circuits, such as broadcasting and telecom systems, as its mica/PTFE construction delivers the desired voltage characteristics.

Due to its combination of high performance, reliability, and cost, the CD5EC430GO3F is suitable for a wide variety of applications. It is the ideal choice for a variety of RF circuit designs that require high insulation resistance, low inductance, and small size. Furthermore, CD5EC430GO3F\'s unique mica/PTFE construction delivers improved performance over other types of capacitors, making it well-suited for many high-voltage applications.
