UPW1C470MDD

The UPW1C470MDD is a miniature radial aluminum electrolytic capacitor from Nichicon’s UPW series, engineered for low impedance and high reliability in compact power designs. It delivers polarized capacitance for board-level power filtering in thermal environments from −55°C to +105°C and is specifically intended for applications that demand robust performance at elevated temperatures.

With a 16 V rated voltage, ±20% tolerance and series-level characteristics optimized for switching power supplies, this part combines compact size (φ5 × 11 mm) and radial-lead packaging for tight-layout installations.

Key Features

• Electrical Specification — 470µF nominal capacitance at 16 V rated voltage with ±20% tolerance, providing bulk energy storage and smoothing for DC rails.
• Low Dissipation Factor — tanδ of 0.16 (at 16 V, 120 Hz, 20°C) for reduced loss in AC and ripple environments.
• Ripple Current Capability — Rated ripple current of 54 mA at 120 Hz and 180 mA at 10 kHz supports dynamic load conditions in power supplies.
• Leakage Current — Low leakage current specified (22.56 µA) after rated voltage applied, aiding in sensitive circuits.
• Temperature & Endurance — Operating range −55°C to +105°C with a rated lifetime of 2000 hours at 105°C for sustained high-temperature operation.
• Mechanical & Package — Compact radial-can construction (φ5 × 11 mm) with 2.0 mm lead spacing; available bulk (no terminal forming) / bag packing for through-hole assembly.
• Reliability Qualification — AEC-Q200 rated to meet automotive-grade reliability expectations for passive components.

Typical Applications

• Switching Power Supplies — Series design emphasizes low impedance and miniature size, making this capacitor suitable for smoothing and decoupling in switching regulators.
• Automotive Electronics — AEC-Q200 qualification and wide temperature range (−55°C to +105°C) make it appropriate for automotive electronic assemblies requiring reliable bulk capacitance.
• Compact Power Filtering — Small φ5 × 11 mm can and 2 mm lead spacing enable placement in space-constrained board layouts for local energy storage and ripple reduction.

Unique Advantages

• Compact form factor: φ5 × 11 mm radial can minimizes PCB space while providing significant capacitance for tight designs.
• Designed for high-temperature duty: Rated for operation up to 105°C with a 2000-hour endurance rating at that temperature for sustained performance in hot environments.
• Automotive-grade reliability: AEC-Q200 rating supports use in environments that require established passive-component reliability standards.
• Good ripple handling: Specified ripple currents (54 mA at 120 Hz, 180 mA at 10 kHz) support dynamic power stages and help maintain voltage stability under load.
• Low loss: tanδ = 0.16 at the rated condition reduces dissipation and improves efficiency in AC/RF ripple scenarios.
