UPW2D471MRD

The UPW2D471MRD is a Nichicon UPW series miniature, low-impedance aluminum electrolytic capacitor in a radial-lead can. It delivers 470 µF capacitance at a 200 V rating with polarized radial leads and is designed for high-reliability power applications such as switching power supplies.

Key electrical characteristics include a capacitance tolerance of -20% to +20%, tanδ of 0.15 (measured at 20°C, 120 Hz), specified low- and high-frequency ripple currents, and an endurance rating of 8000 hours at 105°C. Status: End Of Life.

Key Features

• Capacitance & Tolerance — 470 µF nominal capacitance with a tolerance of -20% to +20%, providing a defined margin for bulk filtering and energy storage.
• Rated Voltage — 200 V DC rating suitable for high-voltage power rails and converter stages.
• Low impedance, switching supply focus — Part of the UPW series specified as miniature-sized, low impedance, and high reliability for switching power supplies.
• Ripple current capability — Low-frequency ripple current of 1.31 A at 120 Hz and high-frequency ripple current of 1.5065 A at 10 kHz, enabling effective smoothing across a range of switching frequencies.
• Endurance & temperature range — Rated for 8000 hours at 105°C and an operating temperature range of -40°C to 105°C for sustained high-temperature performance.
• Construction & package — Radial lead can (φ22 × 50L) with 10 mm lead spacing (±0.5 mm) for through-hole mounting and robust mechanical connection.
• Electrical loss and leakage — Specified tanδ of 0.15 (20°C, 120 Hz) and leakage current of 3860 µA, allowing designers to evaluate dissipation and hold-up behavior precisely.
• AEC‑Q200 rating — Produced to an AEC‑Q200 rating as listed in the product specifications.
• Packaging options — Available in bulk (no terminal forming) or bag packing to support board assembly and inventory handling preferences.

Typical Applications

• Switching power supplies — Bulk filtering and output smoothing where low impedance and specified ripple current at 120 Hz and 10 kHz are required.
• Power conversion modules — Energy storage and decoupling for DC–DC converters and high-voltage rails up to 200 V.
• Automotive electronics — Suitable for automotive-grade designs that reference AEC‑Q200 qualification and require defined endurance at elevated temperatures.
• Industrial power systems — Filtering and smoothing in industrial power supplies operating across -40°C to 105°C with long endurance requirements.

Unique Advantages

• Defined high-voltage capability: 200 V rating supports higher-voltage power rails without stacking multiple capacitors.
• Demonstrated high-temperature endurance: 8000-hour rating at 105°C gives predictable lifetime behavior in thermally stressed environments.
• Broad ripple performance: Specified ripple current at both low (120 Hz) and high (10 kHz) frequencies helps designers size capacitors for real-world switching conditions.
• Compact radial can format: φ22 × 50L package with 10 mm lead spacing provides a through-hole solution with a small footprint for dense power assemblies.
• Traceable electrical loss and leakage data: tanδ (0.15) and leakage current (3860 µA) values allow precise thermal and hold-up calculations.
• AEC‑Q200 listed: Inclusion of AEC‑Q200 in the product specifications supports selection for applications that reference automotive component standards.
