Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are components used in a variety of electronic circuits and applications. The UHE1C102MPT is a high-voltage type capacitance manufactured by United Chemi-Con. It is rated for 2,000 volts and is designed to operate in high-temperature environments up to 85 degrees Celsius. As with most electrolytic capacitors, it operates using a dielectric of aluminum oxide formed between an anode and a cathode.

UHE1C102MPT Application Field and Working Principle

The UHE1C102MPT is typically used as a voltage hold-off element or a spike suppression component in a range of electronic devices. For instance, it is often used in Ethernet drivers, radio transmitters and receivers, battery-powered devices, and motor controls such as electronic gate drivers. It can also be used as a power supply filter, a snubber circuit, and an AC waveform shaper. All of these applications employ a similar working principle.

At the heart of its operation is a metallized film, which serves as both the anode and cathode. This metallized film is connected to a positively and negatively charged electrode. The anode side has a thicker layer of the oxide dielectric, which provides the capacitance for the device. The dielectric holds electrons in a manner similar to a capacitor, thus allowing for the buildup of potential energy.

This potential energy allows the device to suppress voltage spikes, hold off voltages, or serve in a power supply filter role. The capacitance, and thus the device\'s performance, depends on the size of the anode layer as well as the quality of the dielectric material used in the fabrication process.

The UHE1C102MPT offers a good balance between performance and cost. In addition to its high-voltage capability, it is also very reliable and long-lasting. It is also designed to operate at 85 degree Celsius, making it one of the few types of capacitor that can handle the extreme temperatures present in some modern applications.

Considerations of Use

When using the UHE1C102MPT, care should be taken to ensure proper environmental conditions are maintained. As mentioned earlier, the device is designed to operate in ambient temperatures up to 85 degrees Celsius. Beyond this temperature, the device\'s limits are reached and its performance may be adversely affected. In addition, the device may be at risk of thermal runaway if the capacitor is installed in an environment where the temperature rapidly fluctuates.

The device\'s performance may also be affected by electrical disturbances such as spikes, noise, and electromagnetic interference. As such, it is important to ensure that adequate decoupling networks are employed, and that the device is properly shielded and grounded. In addition, care must be taken to ensure the device stays within its rated max voltage. Exceeding this voltage may result in heating, capacitance leakage or even explosions.

Conclusion

The UHE1C102MPT is a high-voltage aluminum electrolytic capacitor manufactured by United Chemi-Con. It can be used in a variety of applications, ranging from Ethernet drivers to motor controls and snubber circuits. Its performance depends on the quality of oxide dielectric and the size of the anode layer, and it is designed to operate at up to 85 degrees Celsius. Finally, proper environmental conditions must be observed during its operation, and extra care must be taken to guard against electrical disturbances and excessive voltages.
