Aluminum electrolytic capacitors are widely used passive components in modern electronic and electrical circuits. These capacitors are primarily employed to store energy and to shift the phase of an alternating current signal. Given their conventional size and negligible induction loss, capacitors are often used to create high frequency resonant circuits. This article dives into the application field and working principle of one of the most popular aluminum electrolytic capacitors: EMVA160ADA681MJA0G.

An EMVA160ADA681MJA0G capacitor is an aluminum electrolytic capacitor which has a single layer anode, similar to what is used in polarized electrolytic capacitors. This capacitor is made of high-purity aluminum foil and two extra-thick layers of dielectric in the form of aluminum oxide. It also has two large terminal leads for mounting, making it ideal for high-frequency applications in which current needs to be passed through with minimal distortion. This makes them well suited for automotive, aerospace and industrial applications.

The working principle of an EMVA160ADA681MJA0G capacitor involves the electric charge being stored within the dielectric material, which is composed of an insulating layer of aluminum oxide. In the presence of an external electric field, the stored charge is unbalanced and starts to flow through the circuit. This phenomenon is known as dielectric absorption. In turn, the electric charge forms a field of polarization, which further assists in storing electric charge in the oxide.

As an aluminium electrolytic capacitor, the EMVA160ADA681MJA0G capacitor has a number of useful properties specifically suited for automotive, aerospace and industrial applications, as compared to other types of capacitors. Its low resistance, high capacitance and low inductance coupled with its good farad stability and low leakage current value, make it ideal for applications in which power factor correction and voltage stabilisation is necessary.

The EMVA160ADA681MJA0G can be used for circuit filtering, blocking and bypassing voltages, oscillator feedbacks and timing circuits. It can also be used in combination with other passive components, such as resistors and inductors, to create LCR circuits which can be used as filters, wave shaping and noise suppression networks. In addition, the EMVA160ADA681MJA0G is well Suited for resonant circuits, which are used in a variety of applications, including radio communication and power supply design.

To further appreciate the capabilities of the EMVA160ADA681MJA0G capacitor, one must consider its self-healing property. In short, the EMVA160ADA681MJA0G capacitor has the ability to repair itself if it is subject to electric pulse damage or voltage overshoot. This is a result of the capacitor’s two-step dielectric formation process. During the process, the capacitor reformulates its dielectric material and restores it to its original form.

Given the high-purity aluminum anode, two extra-thick layers of dielectric, low resistance, high capacitance, low inductance, good farad stability and low leakage current value, the EMVA160ADA681MJA0G is clearly designed to perform its best in demanding and highly sensitive applications. As a result, it is an indispensable component in any plant or machinery requiring an aluminum electrolytic capacitor.
