UPJ1E471MPD

The UPJ1E471MPD is a radial-lead aluminum electrolytic capacitor in Nichicon’s UPJ series, designed for low impedance performance in switching power supplies and general-purpose power circuits. It provides 470 µF capacitance at a 25 V rating with a compact φ10 × 20 mm can and axial lead configuration for through-hole mounting.

Key value propositions include high ripple-handling capability across low and high frequencies, extended endurance at elevated temperature, and low leakage and dissipation characteristics for reliable power filtering and bulk decoupling.

Key Features

• Capacitance and Voltage — 470 µF nominal capacitance with a 25 V rated voltage and ±20% tolerance (measured at 120 Hz, 20°C), suitable for bulk energy storage and smoothing on 25 V rails.
• Low Impedance Design — Part of the UPJ series specified for low impedance performance, making it well suited for switching power supply outputs and decoupling applications.
• Ripple Current Performance — Low-frequency ripple current of 502.2 mA (120 Hz) and high-frequency ripple current of 810 mA (200 kHz) to handle both mains- and switching-generated ripple components.
• Loss and Leakage Characteristics — Dissipation factor (tan δ) of 0.14 at 25 V, 120 Hz and a measured leakage current of 352.5 µA, supporting stable operation in DC bias conditions.
• Extended Endurance — Rated for 5000 hours at 105°C under specified load life conditions, supporting long-term reliability in elevated-temperature environments.
• Package and Mounting — Radial lead (can) construction, size φ10 × 20 mm (10 mm diameter × 20 mm length), lead spacing 5 mm with 0.5 mm tolerance, packaged in bulk (no terminal forming) or bag packing.
• Environmental Compliance — RoHS compliant and currently in mass production.

Typical Applications

• Switching Power Supplies — Output smoothing and energy storage where low impedance and high ripple capability reduce output voltage ripple and improve transient response.
• General-Purpose Power Filtering — Bulk decoupling and smoothing on DC power rails in general-purpose electronic equipment.
• Mixed-Frequency Ripple Suppression — Handling both low-frequency (120 Hz) and high-frequency (200 kHz) ripple components thanks to specified ripple current values at both frequencies.

Unique Advantages

• Proven UPJ low-impedance topology — Optimized for switching supply outputs to reduce ESR and improve voltage stability under load.
• High ripple capability across frequencies — Separate low- and high-frequency ripple current ratings (502.2 mA @120 Hz and 810 mA @200 kHz) let designers address mixed-source ripple without overspecifying parts.
• Long elevated-temperature life — 5000-hour endurance at 105°C provides predictable aging characteristics for designs deployed in hotter operating environments.
• Compact through-hole form factor — φ10 × 20 mm radial can and 5 mm lead spacing deliver a small footprint for high-density PCBs while retaining through-hole mechanical robustness.
• Measurable leakage and loss performance — Specified leakage current and tan δ values help engineers validate thermal and electrical models during design.
• Regulatory readiness — RoHS compliance for designs targeting regulated markets.
