UPJ1E271MPD

Design and Construction

The UPJ1E271MPD is designed with a particularly small footprint for compact designs. The device has an 11.4 mm diameter and a maximum operating height of 6.5 mm. The device is designed with a snap-in mounting, making it very easy to install. The UPJ1E271MPD is constructed from aluminum electrolyte which makes the device both reliable and affordable.

The UPJ1E271MPD features KEMET\'s unique foamless construction which ensures that the capacitor offers exceptional capacitance and reliability performance. This construction comprises of two terminations, each soldered to the top and bottom of a single layer, high-grade aluminum anode. The anode is then coated with an electric insulating material and is then filled with electrolyte. Finally, a cathode is attached to the anode.

Applications

The UPJ1E271MPD is specifically designed for use in high voltage hold-up applications. Its small size and high capacitance make it suitable for applications where space is limited and a high capacitance is required. Examples of such applications include power supplies, line regulation and electric motor control.

The device is also suitable for use in industrial voltage regulation applications where wide voltage swings and a high capacitance are desirable. It is also used in automotive, telecom and computer applications, where its small size and high stable characteristics are seen to be extremely advantageous.

Working Principle

In its simplest form, the UPJ1E271MPD is an electrostatic charge store. An electric field is created in an electrolyte across two electrodes, the anode and cathode. Charge is stored on these electrodes in the form of an electric dipole. This electric field is proportional to the applied voltage and inversely proportional to the distance between the terminals.

As current is injected or extracted from the device, a charge imbalance is created in the electrolyte. This leads to a change in the electric field, resulting in the device either storing or releasing energy in the form of an electrostatic charge. This property makes the capacitor ideal for storing and releasing energy quickly and efficiently.

Conclusion

The UPJ1E271MPD is a small aluminum electrolytic capacitor from KEMET. It is designed for use in applications requiring high performance and reliability and are most suitable for applications where space is limited and high voltage hold-up is needed. Its unique foamless construction ensures that the device offers superior capacitance and reliability performance, making it ideal for mobile and industrial applications.
