UPW2D470MHD

The UPW2D470MHD is a radial-leaded aluminum electrolytic capacitor from Nichicon's UPW series, offering high capacitance in a compact can-style package. The UPW series is described as miniature-sized with low impedance and high reliability for switching power supplies.

With a rated capacitance of 4700 µF at 35 V, long endurance at elevated temperature, and AEC-Q200 component-level qualification, this part is targeted at power filtering and energy-storage roles where high ripple handling and thermal endurance are required. Note: the product status is End Of Life.

Key Features

• Capacitance & Voltage — 4700 µF nominal with tolerance of -20% to +20% at a rated voltage of 35 V.
• Low loss characteristic — tanδ (dissipation factor) of 0.28 measured at 20°C and 120 Hz for predictable AC performance.
• Leakage current — leakage current specified at 888.3 µA.
• High ripple-current capability — low-frequency ripple current 1720 mA and high-frequency ripple current 2555 mA, supporting demanding power-conversion loads.
• Endurance — rated for 7000 hours at 105°C, enabling sustained operation in elevated-temperature environments.
• Operating temperature range — −40°C to +105°C.
• Compact radial package — can dimensions φ12.5 × 25L with radial leads, lead spacing 5.0 mm (±0.5 mm), suited for through-hole mounting in constrained spaces.
• Packaging options — available as Bulk (No Terminal Forming) or Bag Packing.
• Component qualification — AEC-Q200 rating (component-level stress qualification) is listed for this part.

Typical Applications

• Switching power supplies — bulk energy storage and output filtering where low impedance and high ripple handling reduce voltage excursion under load.
• Automotive electronics — component-specified suitability for automotive systems that require robust electrolytic capacitance and AEC-Q200 qualification.
• DC-DC converters and power regulation — smoothing and decoupling for converters and voltage-regulation modules.
• Backup/hold-up circuits — local energy storage to support transient loads and short-duration power hold-up.

Unique Advantages

• High capacitance in a small footprint — 4700 µF packed into a φ12.5 × 25 mm can minimizes board area for bulk storage.
• High ripple-current capability — specified low- and high-frequency ripple currents support converters and switching loads without premature overheating.
• Extended high-temperature endurance — 7000 hours at 105°C helps ensure long-term stability in elevated-temperature applications.
• AEC-Q200 component-level qualification — provides an additional level of stress-test qualification for designs used in demanding environments.
• Series-level low-impedance design — UPW series characterization targets low ESR/impedance for improved transient response in power applications.

Why Choose UPW2D470MHD?
