Frequently Asked Questions
What voltage and capacitance ratings make UUJ2W4R7MNQ1MS suitable for high-voltage power supply designs?
The UUJ2W4R7MNQ1MS provides 4.7 µF capacitance at a 450 V rated voltage, making it ideal for high-voltage DC bus filtering in industrial power supplies and motor drives. Its wet aluminum electrolytic construction handles 450 V bulk storage with a leakage current of only 0.1846 mA.
How do the physical dimensions of UUJ2W4R7MNQ1MS affect PCB layout in industrial inverter designs?
With a 12.5 mm diameter and 16 mm height, the UUJ2W4R7MNQ1MS occupies moderate vertical space on a PCB and requires a 12.5 mm diameter footprint pad. Designers targeting compact 450 V bus rails in inverter or UPS enclosures can use this snap-in style for secure mechanical mounting.
When is UUJ2W4R7MNQ1MS a practical choice for hold-up capacitor applications in switched-mode power supplies?
In SMPS designs with a 450 V intermediate bus, the UUJ2W4R7MNQ1MS provides 4.7 µF hold-up capacitance to sustain output voltage during brief input interruptions. The low 0.1846 mA leakage and wet aluminum construction maintain charge retention over extended hold periods, supporting hold-up time requirements in 100 V to 450 V bus topologies.
