NOJC227M004RWJ

Niobium Oxide Capacitors (NOCs) are a type of electrochemical capacitor that consists of a stack of niobium oxide charged layers. They are most commonly used in power electronic devices such as inverters, rectifiers and AC-DC converters. NOCs offer a number of advantages over other types of electrochemical capacitors, such as higher capacitance, higher energy density, and better performance at higher temperatures.

NOJC227M004RWJ is an NOC device designed by Japanese electronic components manufacturer Rohm. It has a capacitance of 2.2 µF and a maximum temperature rating of 105°C. NOJC227M004RWJ is suitable for use in a variety of applications, including automotive electronics, industrial automation, consumer electronics, and medical equipment.

The working principle underlying NOCs is the same as that of most other types of electrochemical capacitors. When an electric field is applied to two conductive layers of opposite polarity (typically made from niobium oxide), charged particles are drawn toward each other, creating an electric double layer (EDL). The EDL effectively increases the size of the capacitor, resulting in a higher capacitance. Additionally, NOCs are resistant to high temperatures and vibrations, making them well-suited for use in harsh environments.

NOCs typically consist of two niobium oxide layers, a spacer, and a pair of electrodes. The two niobium oxide layers each have a different charge (positive and negative). When a voltage is applied across the two electrodes, an electric field is created between them, which attracts the charged particles on the niobium oxide layers, creating an EDL. This EDL is the basis of the device’s capacitance.

NOCs offer several advantages over other types of electrochemical capacitors, such as higher capacitance, higher energy density, and better performance at higher temperatures. They are also resistant to aging, making them suitable for use in harsh environments. NOJC227M004RWJ has been designed to take advantage of these advantages, making it a reliable and versatile device for a variety of different applications.
