UPW1C472MHD

The UPW1C472MHD is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon's UPW series, configured as a radial lead can. It delivers 4700 μF capacitance at a 16 V rating with low impedance and long-life endurance for demanding power applications.

Designed for use in switching power supplies and other power-management circuits, this part combines high ripple-current capability, extended high-temperature lifetime, and AEC-Q200 rating for designs that require robust, compact bulk capacitance.

Key Features

• Capacitance & Voltage — 4700 μF (4.7 mF) rated at 16 V with a capacitance tolerance of −20% to +20%.
• Low Impedance — 36 mΩ impedance to support efficient decoupling and smoothing in power rails.
• High Ripple-Current Handling — Low-frequency ripple current: 2.5585 A (120 Hz); high-frequency ripple current: 3.01 A (10 kHz), enabling reliable performance under AC-stressed conditions.
• Loss Characteristics — tan δ = 0.16 measured at 20°C, 120 Hz for predictable dissipation behavior in power circuits.
• Leakage Current — Specified leakage current of 2256 μA after rated voltage application, useful for system power-standby calculations.
• Extended Endurance — Life rating of 8000 hours at 105°C for long-term stability in elevated-temperature environments.
• Robust Temperature Range — Operates from −55°C to +105°C to cover a wide range of environmental conditions.
• Package & Mounting — Radial lead can, size φ16 × 30.5 L (L: 3.05 × D: 1.6 cm), lead spacing 7.5 mm, available in bulk or bag packing.
• Quality Rating — Ratings include AEC-Q200.

Typical Applications

• Switching Power Supplies — Bulk smoothing and output filtering where high ripple current capability and low impedance reduce voltage ripple.
• Power Management Modules — Energy storage and decoupling in DC-DC converters and power conditioning circuits.
• Industrial Electronics — Bulk capacitance for motor drivers, controllers, and power distribution under wide temperature ranges.
• Automotive Electronic Systems — Suitable for automotive-related designs requiring AEC-Q200-rated passive components for enhanced reliability.

Unique Advantages

• High ripple tolerance: Rated ripple currents of 2.5585 A (120 Hz) and 3.01 A (10 kHz) support demanding AC stress in power rails.
