The EKYB250ELL102MJ20S is a type of AECs manufactured by KEMET Corporation. It has excellent noise suppression capabilities and is incredibly reliable. This article looks at the application fields and working principle of the EKYB250ELL102MJ20S.

Application fields of the EKYB250ELL102MJ20S

The EKYB250ELL102MJ20S is suitable for a range of applications, such as consumer electronics, power supplies, industrial equipment and automotive and aviation electronics. It can be used in circuit boards and electronic products of different voltage and current ranges. Its high temperature performance and low impedance make it ideal for applications with a wide temperature range. It can also be used in high frequency circuits, such as mobile phones, where suppression of electromagnetic interference (EMI) and radio frequency interference (RFI) is necessary.

Working principle of the EKYB250ELL102MJ20S

The EKYB250ELL102MJ20S is a non-polar electrolytic capacitor. Its construction consists of an anode formed from aluminum foil, a special dielectric, electrolytic (the most common is an anionic solution with an organic solvent), and a cathode formed from an external aluminum/tin alloy case. The cathode coating is electrically connected to the transistorism circuit and acts as a gate ,while the anode is electrolized with the electrolytic solution, and forms the electrical path in reverse.

The anode and the cathode form an extremely thin Oxide film, enabling AECs to reduce the size of their housing. This high capacitance per volume ratio is the reason why AECs are so popular in small devices with low power requirements.

When there is a voltage difference between both sides of the capacitor, electrons from the anode move to the cathode and accumulate, forming an electric field. As the field strength increases, so does the current, causing a high-frequency, high-pressure current to flow. As the process continues, the Oxide film at the anode and cathode continues to weaken, and the current flow decreases until it is eventually blocked.

The current that passes through AECs is an alternating current and the impedance of AECs will reduce as the frequency of the current increases. For this reason, AECs are also suitable for use in high-frequency environments as they can resist high-frequency interference and reduce the transmission losses of power supplies.
