UPS1E471MPD

The UPS1E471MPD is a radial-lead aluminum electrolytic capacitor designed for general-purpose power applications. It belongs to Nichicon's UPS series, a miniature-sized, low-impedance family intended for use in switching power supplies and other compact power circuits.

This part delivers 470 µF at 25 V with a wide operating temperature range (−55°C to 105°C), defined ripple-current capability, and a 2,000-hour endurance at 105°C—making it suitable where compact size, reliable filtering, and thermal tolerance are required.

Key Features

• Capacitance & Voltage — 470 µF rated capacitance at 25 V provides bulk energy storage and decoupling for low-voltage power rails.
• Low Impedance — Specified impedance of 140 mΩ supports effective smoothing and transient handling in switching circuits.
• Ripple Current Handling — Low-frequency ripple current of 568 mA (120 Hz) and high-frequency ripple current of 800 mA (10 kHz) for reliable performance across switching frequencies.
• Thermal and Endurance Specs — Rated for −55°C to 105°C operation with 2,000 hours life at 105°C for long-term stability in elevated temperatures.
• Leakage and Loss — Leakage current of 352.5 µA and tangent of loss angle (tan δ) of 0.14 measured at 20°C, 120 Hz indicate predictable dissipation and self‑loss behavior.
• Compact Radial Package — φ10 × 16 mm can with radial leads and 5 mm lead spacing (±0.5 mm) for through-hole mounting in space‑constrained PCBs; available in bulk or bag packing.
• RoHS Compliant — Meets RoHS directive requirements for restricted substances.

Typical Applications

• Switching Power Supplies — Bulk filtering and output smoothing where low impedance and defined ripple-current capability are required.
• DC Power Rails — Decoupling and hold-up capacitors on low-voltage boards supporting transient suppression and energy storage.
• Power Modules and Converters — Compact radial package suited for modular power designs needing high ripple handling in limited PCB space.

Unique Advantages

• Compact energy storage: 470 µF in a φ10 × 16 mm can minimizes board footprint while providing useful bulk capacitance.
• Defined ripple capability: Specified ripple currents at both low and high frequencies allow designers to match the component to switching and line-frequency conditions.
• Wide temperature tolerance: −55°C to 105°C rating enables use across harsh thermal environments without derating beyond specified limits.
• Endurance at elevated temperature: 2,000-hour life at 105°C gives predictable long-term behavior for thermal-stressed power designs.
• Through-hole robustness: Radial-lead construction and fixed 5 mm lead spacing simplify assembly and mechanical stability on PCBs.
• Regulatory compliance: RoHS conformity supports compliant product builds and supply-chain requirements.
