UPW1J471MHD

The UPW1J471MHD is a radial-lead aluminum electrolytic capacitor designed for compact power systems and switching power supplies. It offers a 470 µF capacitance at a 63 V rating in a miniature φ12.5 × 25 mm can, delivering low impedance and reliable ripple handling for power filtering and energy storage.

Built for demanding thermal environments, this part supports an operating temperature range of −55 °C to +105 °C and a rated life of 7000 hours at 105 °C, making it suitable for long-life, high-reliability applications including those requiring AEC-Q200 qualification.

Key Features

• Capacitance and Voltage — 470 µF nominal capacitance with a 63 V rated voltage and a tolerance of −20% to +20% for stable bulk energy storage.
• Low Impedance — 140 mΩ impedance that improves transient response and reduces voltage ripple in power rails.
• High Ripple Current Capability — Rated ripple currents of 1.29 A at 120 Hz and 1.72 A at 10 kHz enable effective smoothing at both low and high switching frequencies.
• Loss Tangent — tanδ of 0.09 (measured at 20 °C, 120 Hz) for predictable AC loss behavior in filtering applications.
• Long Endurance — 7000 hours life at 105 °C under rated voltage and ripple conditions for extended service life in thermal stress environments.
• Wide Temperature Range — Rated for −55 °C to +105 °C to support a broad set of environmental conditions.
• Compact Radial Can — Package φ12.5 × 25 mm with 5 mm lead spacing and radial-lead mounting for through-hole assemblies and robust mechanical retention.
• AEC-Q200 Rated — Series-level AEC-Q200 rating for automotive-grade reliability where applicable.
• Polarized, Pressure Relief — Polarized aluminum electrolytic construction with pressure relief vent typical of radial lead types for safety in fault conditions.

Typical Applications

• Switching Power Supplies — Bulk filtering and output smoothing for regulated supplies in compact converters.
• DC-DC Converters — Energy storage and ripple suppression in both low- and high-frequency converter stages.
• Automotive Electronics — Power filtering and decoupling in automotive subsystems where AEC-Q200 qualification is required.
• Industrial Power Modules — Filtering and buffer capacitance in industrial control and power management modules operating across wide temperature ranges.

Unique Advantages

• High ripple handling across frequencies: Specified ripple current of 1.29 A (120 Hz) and 1.72 A (10 kHz) combined with frequency coefficients from the UPW series datasheet enables designers to size capacitors for both low- and high-frequency switching environments.
• Low impedance for improved transient response: 140 mΩ impedance reduces voltage droop during load transients, improving regulator stability and performance.
• Long high-temperature life: 7000 hours at 105 °C provides predictable long-term performance in thermally demanding applications.
• Compact through-hole form factor: φ12.5 × 25 mm radial can with 5 mm lead spacing offers a space-efficient, mechanically robust solution for PCB-mounted power sections.
• Automotive-capable design: AEC-Q200 rating supports use in designs requiring automotive-grade reliability and testing standards.
• Clear electrical characterization: Specified tanδ, leakage current, and impedance values allow precise thermal and electrical design trade-offs.
