UPW2E471MRD

The UPW2E471MRD is a radial-lead aluminum electrolytic capacitor in Nichicon's UPW series, offering low impedance and designed for demanding power applications. With a 470 µF capacitance at 250 V rating and a compact can-style radial package, it targets switching power supplies, power management circuits and automotive electrical systems that require robust bulk energy storage.

Key value propositions include long endurance (8,000 hours at 105°C), measurable low-loss performance at 120 Hz (tanδ 0.15 at 20°C), and high ripple-current capability across low and high frequencies—supporting reliable operation under continuous power-stressed conditions.

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance with a rated voltage of 250 V and capacitance tolerance of -20% to +20% for predictable bulk energy storage.
• Low Loss Factor — Tangent of loss angle (tanδ) specified at 0.15 (measured at 20°C, 120 Hz), supporting efficient AC performance in power filtering and decoupling roles.
• High Ripple Current Capability — Rated low-frequency ripple current of 1,350 mA at 120 Hz and high-frequency ripple current of 1,552.5 mA at 10 kHz to handle switching and high-frequency stresses.
• Thermal Endurance — Qualified for 8,000 hours at 105°C, providing long-term stability in elevated-temperature environments.
• Operating Temperature Range — Rated for operation from -40°C to +105°C to cover a wide range of environmental conditions.
• Through‑Hole Radial Package — Radial-lead, can-style package with φ25 × 50 mm dimensions (L: 5 × D: 2.5 cm) and 12.5 mm lead spacing (±0.5 mm), suitable for robust through-hole assembly and mechanical stress resistance.
• Automotive-Grade Rating — AEC-Q200 rating, indicating suitability for automotive electronics applications that demand component-level reliability.
• Packaging Options — Available in bulk (no terminal forming) and bag packing to accommodate different production workflows.

Typical Applications

• Switching Power Supplies — Bulk energy buffering and output smoothing for switching regulators and converters where low impedance and high ripple handling are required.
• Automotive Power Electronics — Energy storage and filtering in automotive control modules and power distribution systems, backed by the AEC-Q200 rating and high-temperature endurance.
• Industrial Power Management — DC bus support, inrush current absorption and smoothing in industrial converters and motor drives operating at elevated temperatures.
• High‑Frequency DC‑DC Converters — Support for high-frequency ripple currents (10 kHz) to maintain stable output under switching loads.

Unique Advantages

• Long-Term High-Temperature Reliability: 8,000-hour endurance at 105°C provides predictable lifetime performance in thermally demanding installations.
• High Ripple-Handling Capability: Specified ripple currents at both 120 Hz and 10 kHz enable use across switching and high-frequency power stages without excessive heating.
• Compact Through-Hole Form Factor: φ25 × 50 mm radial can with 12.5 mm lead spacing combines compact footprint with mechanical robustness for board-level power applications.
• Automotive-Grade Qualification: AEC-Q200 rating supports deployment in automotive electronics and other applications where component qualification matters.
• Measured Low Dissipation Factor: tanδ 0.15 at 20°C/120 Hz reduces AC losses and helps maintain efficiency in filtering roles.
