Aluminum electrolytic capacitors are one of the most important components in electronic products due to their high reliability, wide range of capacitance, and low equivalent series resistance (ESR). The UKT1V4R7MDD1TA series aluminum electrolytic capacitors are designed to provide high capacitance values with low ESR and long life characteristics at high temperature operation. They are suitable for many application fields, such as filtering, storage, decoupling and bypassing.

The UKT1V4R7MDD1TA aluminum electrolytic capacitors are constructed with non-solid electrolyte, meaning that they have no solid electrolyte and employ an internal thin-film aluminum oxide dielectric for higher reliability and low leakage current. This type of capacitor utilizes the same construction as non-solid aluminum electrolytic capacitors, but the electrolyte is a liquid polymer material instead of a solid. This construction ensures the device has better leakage current characteristics, higher temperature ratings, better shelf-life, and improved vibration resistance compared to other non-solid aluminum electrolytic capacitors.

The UKT1V4R7MDD1TA aluminum electrolytic capacitors have a very low equivalent series resistance (ESR), which enables them to have low power consumption and high ripple current capabilities. The ESR helps to reduce power loss, reduce self-heating, minimize hum, and prevent voltage droop. The improved capacitance stability of these capacitors helps them run reliably over a longer period of time. The very low ESR also helps provide much higher capacitance values for the same size and volume of the capacitor, which enables these capacitors to deliver more current.

The UKT1V4R7MDD1TA aluminum electrolytic capacitors are suitable for use in a wide range of applications, such as power supplies, LED lighting, switch mode power supplies, telecom equipment, and consumer products. They are typically used in decoupling, bypassing, filtering, and storage applications. The capacitance range of these capacitors is from 1µF to 470µF, depending on the device size, and they can operate at operating temperatures of up to 125°C.

The working principle of the UKT1V4R7MDD1TA aluminum electrolytic capacitors is fairly simple. The capacitor comprises two electrodes separated by a dielectric material, usually an aluminum oxide layer. When a voltage is applied across the plates, electric field lines appear and are concentrated by the oxide layer, allowing electron movement through it. Electrons flow through, creating a current. The buildup of positive and negative charges in the capacitor causes a capacitance value which stores an electrical charge.

The UKT1V4R7MDD1TA aluminum electrolytic capacitors are designed with a long life in mind. With very low internal impedance and excellent capacitance stability, these capacitors are excellent for all kinds of applications. Highly reliable and efficient, these capacitors are a great choice for many application fields, providing excellent capacitance values with low ESR and long life characteristics.
