Aluminum - Polymer Capacitors are popular, reliable and cost-effective out of all the available capacitors. They are characterized by their low profile, small size, low cost, excellent frequency response, low dielectric absorption and high insulation resistance. The 128ULR6R3MFH specifically is a multi-layer aluminum-polymer capacitor with a four layer construction and a small footprint of 0.70mm x 0.70mm. It offers high capacitance and low ESR values and is designed for circuit board space-sensitive applications.

The core component of all aluminum-polymer capacitors is a solid aluminum oxide with a special dielectric, which is either sprayed or mixed in an electrolytic solution. This is then coated onto a polymer substrate, and a metallized casing is created around it in order to ensure electrical insulation. The largest advantages of these capacitors are their small footprint and low cost and the fact that they are highly reliable and provide excellent high frequency performance in addition to their low inductance and high stability.

The application of the 128ULR6R3MFH specifically is gaining popularity in the fields of communication systems and consumer electronics, as they provide capacitance, low inductance and high stability in wide range of frequencies. These are particularly useful in high switching frequency, digital signal processing and high current applications. Further, they provide good pulse performance and high working operating temperature, making them suitable for consumer electronics that require long service life and high reliability.

The working principle of the 128ULR6R3MFH is relatively simple and straightforward. This multi-layer capacitor is designed with four layers – two of which are comprised of an electrolytic solution and the other two layers consisting of a polymer dielectric. Electrical energy is stored in the capacitor by an electrostatic field existing between the two layers of the capacitor, thus creating a higher level of capacitance as well as lower levels of ESR and inductance.

The 128ULR6R3MFH is a great option in terms of aluminum-polymer capacitors that can offer strong performance while having a small footprint and a cost-effective price tag. It is highly reliable, offers a wide range of frequencies, and is particularly suitable for high quality, long-term projects that involve high switching frequency, digital signal processing and high current applications.
