UPW1E471MPD6

The UPW1E471MPD6 is an aluminum electrolytic, radial‑lead capacitor in a compact can package designed for switching power supply applications. It delivers 470 µF capacitance at a 25 V rating with a polarized radial lead form factor and is part of Nichicon's UPW series.

Engineered for robust operation across a wide temperature range (−55 °C to 105 °C) and qualified to AEC‑Q200, this component targets automotive and other demanding power‑electronics environments where low impedance, compact size, and long life are required.

Key Features

• Electrical Performance — 470 µF capacitance at 25 V with an impedance of 130 mOhm, providing effective bulk energy storage and low AC resistance for power filtering and decoupling.
• Ripple Current Handling — Rated ripple current of 746.3 mA at 120 Hz and 995 mA at 10 kHz, supporting both low‑ and high‑frequency ripple conditions encountered in switch‑mode supplies.
• Reliability & Qualification — AEC‑Q200 rated with a specified lifetime of 3000 hours at 105 °C, offering traceable reliability for automotive and similarly demanding applications.
• Wide Temperature Range — Operates from −55 °C to 105 °C to accommodate extended environmental ranges common in automotive electronics and industrial power systems.
• Compact Radial Can Package — Radial lead mounting with 3.5 mm lead spacing and a small footprint (L: 2 cm × D: 0.8 cm) for space‑constrained board layouts.
• Capacitance Tolerance — ±20% tolerance (measured at 120 Hz, 20 °C) to support predictable system design and margining.

Typical Applications

• Switching Power Supplies — Bulk filtering and output decoupling in DC–DC converters and SMPS to reduce output ripple and stabilize control loops.
• Automotive Electronic Modules — Power conditioning and energy storage in control modules where AEC‑Q200 qualification and wide temperature operation are required.
• Power Management in Harsh Environments — Use in industrial and mobile power systems that demand long life at elevated temperature and reliable ripple handling.

Unique Advantages

• Low Impedance for Improved Transient Response: 130 mOhm impedance helps reduce voltage droop during load transients in switching regulators.
• High Ripple Capability Across Frequencies: Specified ripple currents at 120 Hz and 10 kHz enable designers to size capacitors for both low‑frequency smoothing and high‑frequency switching conditions.
• Automotive‑Grade Qualification: AEC‑Q200 rating and a 3000‑hour endurance at 105 °C provide design confidence for vehicle electrical systems and other regulated applications.
• Compact, Through‑Hole Package: Radial lead, can‑style package with 3.5 mm lead spacing delivers a small PCB footprint while retaining robust mechanical mounting.
• Wide Operating Temperature: −55 °C to 105 °C specification supports deployment across a broad range of environmental conditions.
