Aluminum electrolytic capacitors are capacitors – electronic components used to store and release electrical energy in electrical circuits – that contain a metal-based anode, separated from its metal-based cathode by an electrolyte solution. The UMF1V1R5MDD1TP is a type of aluminum electrolytic capacitor specifically designed for motor-start circuits. The capacitor provides a mechanical boost to the electrical current for short moments when starting the motor.

Introduction

The UMF1V1R5MDD1TP aluminum electrolytic capacitor typically operates between 250V to 600V AC, which makes it a suitable choice for use in various motor-start circuits. It is rated at 10,000 hours at an operating temperature of -40°C to +105°C. The DC leakage current is less than 0.005CV or 3.0uA, whichever is less. Additionally, the surge current capability is 1,800A and it features a capacitance of 1.5uF.

Application Field

The UMF1V1R5MDD1TP aluminum electrolytic capacitor is suitable for use in a number of motor-start circuits. Its surge current capability, as well as its low leakage and high capacitance, make it capable of supplying the large, short-term spikes of current found in starting many motors. Its low leakage and extremely high surge current capability also make it suitable for use in terms of automotive, household and industrial applications.

The UMF1V1R5MDD1TP is also widely used in power-supply circuits and applies improvements in motor-start applications. It can support robust operation in extreme temperatures due to its long life-span and thermal capability, as well as its high capacitance and resistance to dielectric breakdown.

Working Principle

The UMF1V1R5MDD1TP aluminum electrolytic capacitor features a housing sealed with a resistant, electrolytic resin. Inside, an electrolyte layer is used to separate the anode and cathode of the device. During operation, electrons move from the anode to the cathode, creating a capacitance.

The capacitance of the capacitor is determined by the ratio of its anode area to the gap between the anode and cathode, as well as by the type of electrolyte used, which directly affects the internal impedance and the dielectric strength of the device.

When the voltage is applied to the capacitor, current starts to flow and the device stores electrical energy. When the voltage is removed, the current is released, allowing the capacitor to serve as a source of electrical energy.

Conclusion

The UMF1V1R5MDD1TP aluminum electrolytic capacitor is an excellent choice for use in motor-start circuits. It offers high capacitance and low leakage while also providing a high surge current capability and thermally-robust operation in extreme temperatures. The device utilizes an electrolyte-filled housing to separate its anode and cathode, allowing it to store and release electrical energy based on changes in voltage.
