What are the key features of UVZ1H472MRD?
- Large 4700 µF capacitance for bulk energy storage and low-frequency ripple filtering in AC-DC power supplies and motor drives
- 20 mm diameter through-hole radial package enables high-capacitance density in industrial power supply PCB layouts
- Wet aluminum electrolytic construction provides high volumetric efficiency and cost-effective energy buffering at low ESR
- RoHS/Pb-free (e3) compliant process meets environmental requirements for industrial and consumer power electronics
What is UVZ1H472MRD used for?
The UVZ1H472MRD is designed for DC link bulk capacitance and output smoothing in industrial AC-DC power supplies, motor drive inverters, and uninterruptible power supply (UPS) systems where large capacitance values are needed to reduce 100 Hz or 120 Hz ripple voltage. Its 4700 µF rating provides substantial charge storage, allowing output voltage hold-up during brief input interruptions in 50 Hz and 60 Hz mains-powered converters. The through-hole radial package is appropriate for high-power PCB assemblies and power modules that require robust mechanical mounting capable of withstanding mechanical stress from component weight.

Frequently Asked Questions
What capacitance and voltage rating does the UVZ1H472MRD provide, and for what power supply topologies is it suited?
The UVZ1H472MRD provides 4700 µF capacitance at a voltage rating consistent with the 1H series designation (50 V DC working voltage). This large capacitance makes it suitable for DC bus smoothing capacitors in full-bridge AC-DC rectifiers, buck converter output filters requiring low 100 Hz ripple, and UPS systems needing several hundred milliseconds of hold-up time during 230 V mains interruptions.
How does the 20 mm diameter body of the UVZ1H472MRD affect PCB layout in compact power supply designs?
The 20 mm diameter radial body of the UVZ1H472MRD requires PCB pad spacing typically of 10 mm lead pitch and a 20 mm clearance circle, which must be factored into the PCB layout alongside adjacent heat-generating components. In compact industrial power supplies, this capacitor is commonly mounted near the board edge or in a dedicated capacitor bank section to avoid thermally coupling with high-temperature inductors or diodes that could reduce the capacitor's operating life below the rated 2000 hours at 85°C.
What is the maximum leakage current of the UVZ1H472MRD, and how does this affect long-term energy storage applications?
The UVZ1H472MRD specifies a maximum leakage current of 7.05 mA at rated voltage. In long-term energy storage or standby power applications such as UPS hold-up circuits, this leakage dissipates approximately 350 mW at 50 V, which is acceptable for short hold-up times of a few seconds but must be accounted for in thermal budgeting. For extended storage buffers exceeding 60 seconds, film capacitors or supercapacitors with leakage below 1 mA would be more energy-efficient alternatives.
How does the aluminum wet electrolytic construction of the UVZ1H472MRD compare to solid polymer capacitors for switching power supply output filtering?
Wet aluminum electrolytic capacitors like the UVZ1H472MRD offer significantly higher capacitance per unit cost compared to solid polymer alternatives, with 4700 µF achievable in a single 20 mm diameter package at a fraction of the cost of equivalent-capacitance solid polymer arrays. However, solid polymer capacitors provide lower ESR (typically 5 mΩ to 20 mΩ versus 50 mΩ to 200 mΩ for wet electrolytics) and longer lifetime at high temperatures above 105°C. The wet construction of the UVZ1H472MRD is well-matched to industrial power supplies operating below 85°C ambient where cost and high capacitance take priority over ESR performance.
