UPW1J471MHD3

The UPW1J471MHD3 is a miniature, high-reliability aluminum electrolytic capacitor in Nichicon’s UPW series. It is a radial-lead, low-impedance device engineered for demanding power applications.

Built for switching power supplies and automotive power systems, this part delivers 470 µF at 63 V with high ripple-handling capability and extended endurance—8000 hours at 105°C—making it suitable for compact, high-stress power designs.

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance with a rated voltage of 63 V and ±20% tolerance at 120 Hz, 20°C.
• Low Impedance — Specified impedance of 118 mΩ to support stable power delivery and improved transient response in switching circuits.
• High Ripple Current Capability — Low-frequency ripple current 1.327 A (120 Hz) and high-frequency ripple current 1.77 A (10 kHz) for robust AC stress handling.
• Long Endurance at Elevated Temperature — Rated life of 8000 hours at 105°C under DC bias plus rated ripple current.
• Wide Temperature Range — Operates from −55°C to 105°C for use across broad environmental conditions.
• Controlled Leakage and Loss Characteristics — Leakage current specified at 888.3 µA and tan δ of 0.09 (20°C, 120 Hz), supporting predictable performance in filter and bulk-storage roles.
• Compact Radial Can Package — Dimension φ16 × 20 mm (lead spacing 7.5 mm) in a radial lead can; available in bulk (no terminal forming) or bag packing.
• AEC-Q200 Rated — Qualified to AEC-Q200 for use in automotive applications where that level of component qualification is required.
• Safety Feature — Radial lead construction includes a pressure relief vent for safer operation under fault or end-of-life conditions.

Typical Applications

• Switching Power Supplies — Bulk and output filtering in compact switching supplies where low impedance and high ripple current are required.
• Automotive Electronics — Power smoothing and energy storage in automotive modules, supported by the part’s AEC-Q200 rating and 105°C endurance.
• DC-DC Converters and Power Modules — Bulk decoupling and transient support in compact converter designs benefitting from the capacitor’s high ripple capability and low impedance.

Unique Advantages

• Compact, High-Capacitance Form — 470 µF in a φ16 × 20 mm can provides significant energy storage in a small footprint for space-constrained designs.
• Designed for High Ripple Environments — Specified ripple currents at both low and high frequencies enable reliable operation in switching and pulse applications.
• Extended High-Temperature Life — 8000 hours at 105°C gives predictable long-term performance under elevated thermal stress.
• Automotive-Grade Qualification — AEC-Q200 rating aligns the part with automotive electronic design requirements where component qualification is needed.
• Low Loss and Controlled Leakage — Low tan δ and defined leakage current support efficient filtering and stable long-term behavior in power circuits.
• Serviceable Radial-Lead Package — Through-hole radial leads and standard 7.5 mm spacing simplify prototyping, repair, and integration into legacy layouts.
