UPA1A471MPD

The UPA1A471MPD from Nichicon is a miniature, radial‑lead aluminum electrolytic capacitor designed for switching power supply and general purpose power‑filtering applications. It combines low impedance and high ripple current capability in a compact radial can package.

Key design attributes include a 470 µF capacitance at 10 V, low impedance (180 mΩ), RoHS compliance, and rated operation across −55°C to +105°C with a rated lifetime of 3000 hours at 105°C.

Key Features

• Electrical Performance — 470 µF capacitance at 10 V with ±20% tolerance, and a low impedance of 180 mΩ to support effective smoothing and decoupling in power circuits.
• High Ripple Current Capability — Rated ripple current of 472.5 mA at 120 Hz and 630 mA at 10 kHz to handle switching and high‑frequency ripple loads.
• Low Loss — Characteristic loss tangent for 10 V applications (tan δ ≤ 0.19 at 120 Hz, 20°C) to minimize dissipation in AC conditions.
• Compact Radial Package — Radial can construction with 3.5 mm lead spacing and compact dimensions (L: 1.15 × D: 0.8 cm) for space‑constrained board layouts.
• Wide Temperature Range & Reliability — Operates from −55°C to +105°C and is specified for 3000 hours at 105°C, supporting sustained elevated‑temperature use.
• Low Leakage — Leakage current after 1 minute at 20°C is specified at ≤ 0.03CV or 4 µA (whichever is greater), aiding long‑term circuit stability.
• Compliance — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863) for environmental regulatory requirements.

Typical Applications

• Switching Power Supplies — Provides bulk smoothing and output filtering where low impedance and high ripple current handling are needed.
• General Purpose Power Filtering — Useful for decoupling and energy storage in general electronic power rails that require a compact radial electrolytic.
• Compact Radial‑Lead Circuits — Suitable for PCB designs that require a small footprint radial can with reliable performance across a wide temperature range.

Unique Advantages

• Low Impedance for Cleaner Outputs: The 180 mΩ impedance reduces voltage ripple and improves transient response in power rails.
• Frequency‑Capable Ripple Handling: Specified ripple currents at 120 Hz and 10 kHz demonstrate capability across switching and higher‑frequency environments.
• Space‑Saving Form Factor: Small L × D dimensions and 3.5 mm lead spacing enable tighter placement and compact power module designs.
• Robust Thermal Endurance: Rated for operation to +105°C with a specified 3000‑hour lifetime at that temperature, supporting sustained use in warmer operating environments.
• Predictable Leakage and Loss: Defined leakage current limits and tan δ values help engineers budget losses and design reliable power systems.
• RoHS Compliance: Meets applicable RoHS directives for environmentally regulated assemblies.
