Mica and PTFE capacitors are components used in electrical and electronic circuits to store energy. The CMR03E390JOYM capacitor is one such component. It is a discrete non-polarized capacitor made of mica and PTFE.

The CMR03E390JOYM capacitor is characterized by its maximum working voltage of 390VAC, a failure rate of 0.1% (1000 hours), and a capacitance of 3 pF. It is one of the smallest commercially available capacitors, measuring just 0.01 inches in diameter and 0.03 inches in height. This makes it suitable for use in applications where space is at a premium, such as on PCBs or in small applications.

The CMR03E390JOYM capacitor has a wide range of applications, including power line filters, RF filters, oscillators and amplifiers, and data line protection. It is also often used in automotive applications due to its small size and high working voltage. In automotive applications, the capacitor can protect engine components from voltage spikes, reduce the risk of electrical fires caused by arcing, and reduce the amount of electrical noise that can interfere with other components in the car.

The working principle of the CMR03E390JOYM capacitor is based on the concept of capacitance. Capacitance is the inherent ability of two metal plates to store and release an electrical charge. When an electrical charge is applied to the metal plates, they store the charge until the electrical charge is removed. When the electrical charge is removed, the metal plates release the charge, resulting in an electric field. This electric field can be used to power circuits, prevent interference from other electrical signals, or filter out noise.

The CMR03E390JOYM capacitor is a reliable and cost-effective solution for a wide range of applications and is often used in automotive, industrial, and consumer devices. With its small size and high working voltage, it is well-suited for use in harsh environments or applications where space is at a premium. It is also resistant to shock and vibration and can withstand high temperatures.
