Mica and PTFE capacitors are widely used in many electronic applications. The CD16FD821JO3 capacitor is a potent tool for improving the performance of such applications. This article will focus on the application fields and working principles of this component.

Applications

The CD16FD821JO3 capacitor is a popular choice for decoupling and filtering applications. The component is used in order to filter out high frequency noise that could otherwise interfere with the smooth operation of other components in the circuit. Additionally, it is also used in high frequency power supplies and radio frequency circuits depending on its configuration.

It is capable of withstanding rated voltages of up to 250 VAC and 40 VDC. This makes the capacitor a versatile choice that can be used in a variety of applications. Furthermore, its lower equivalent series resistance (ESR) allows it to deliver more power to circuits. This makes it suitable for applications that require high capacitance and low ESR, such as smoothing of power supply voltage, capacitive voltage dividers, or suppression of high frequency noise.

Working Principle

A CD16FD821JO3 capacitor is composed of two PTFE dielectrics and one mica dielectric. This assembly is then placed in a metal canister. The two PTFE plates act as electrodes, while the mica dielectric acts as an insulator between them, allowing for a thicker energy storage dielectric. PTFE capacitors don’t suffer from “dielectric hysteresis”, meaning they don’t suffer from a phenomenon wherein the dielectric changes from an insulating to a conductive state over time. This makes the CD16FD821JO3 particularly suitable for applications that require consistency in the capacitance value or improved stability.

The internal structure of the CD16FD821JO3 offers great advantages. The capacitor has a high thermal dissipation rating and offers improved capacitance stability. It also has improved dielectric absorption and low leakage current. Additionally, its power derating is excellent, allowing it to be operated reliably even at high temperatures.

Conclusion

The CD16FD821JO3 capacitor is a versatile component made up of two PTFE dielectrics and one mica dielectric. It is used in applications such as decoupling and filtering, high frequency power supplies, radio frequency circuits, smoothing of power supply voltage, capacitive voltage dividers, and suppression of high frequency noise. The capacitor has a high thermal dissipation rating, offers improved capacitance stability, improved dielectric absorption, low leakage current, and excellent power derating, making it an ideal choice for many applications.
