UPA1E331MPD1TD Capacitors

Aluminum electrolytic capacitors are widely used in modern electrical equipment, mainly because of the following outstanding performance: wide temperature range, wide capacitance range and long life. UPA1E331MPD1TD belongs to a type of aluminum electrolytic capacitors, which has great advantages in application field and working principle.

Application Field:

UPA1E331MPD1TD aluminum electrolytic capacitor is widely used in power supply and filter circuit for its long life and low cost. It has extremely low internal resistance and low temperature drift. The tantalum capacitors offer good temperature characteristics and low relaxation current. Such capacitors are also widely used in high-frequency filters, EMI filters, high voltage DC power supply and some transducer circuits.

Aluminum electrolytic capacitors are suitable for audio, radio, power supplies and other high frequency circuits. In addition, aluminum electrolytic capacitors are also used in pulse circuits for their fast response time. Moreover, electrolytic capacitors offer enough energy storage capacity and can reduce energy consumption in high voltage power stages.

UPA1E331MPD1TD is an aluminum electrolytic capacitor which has mainly non-solid high capacitance and relatively low ESR characteristics. Due to this, It is widely used in various fields such as audio equipment (amplifiers, equalizers and etc.), oscilloscope, motor drives, etc.

Working Principle:

Aluminum electrolytic capacitors, as their name implies, are capacitors consisting of an anode with a thin aluminum oxide layer acting as a dielectric, a cathode and an electrolyte. The principles of their operation are mainly based on the different dielectric constants of the electrolyte and the aluminum oxide layer. The aluminum oxide layer has a much higher dielectric constant than the electrolyte.

When a voltage is applied to an aluminum electrolytic capacitor, the electrolyte molecules absorb electrons from the anode and discharge them through the cathode. As the capacitance of an aluminum electrolytic capacitor increases, the electrolyte molecules are pushed further away from each other, and the capacitance decreases. This effect is called dielectric breakdown.

UPA1E331MPD1TD is an aluminum electrolytic capacitor,with a larger physical size compared with a normal electrolytic capacitor. The thicker oxide layer increases the capacitance to achieve better performance and longer life.

Conclusion:

UPA1E331MPD1TD is an aluminum electrolytic capacitor which has wide application fields and great advantages in working principle. It is widely used in power supply and filters circuit for its long life and relatively low cost and it has excellent low temperature drift, high frequency response and good temperature characteristics.
