UPJ1A471MPD

The UPJ1A471MPD is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon's UPJ series. It is a radial-lead, polarized capacitor specified at 470 µF and 10 V, optimized for power-filtering roles where compact size and stable performance are required.

Designed for general-purpose use and for switching power supplies, this device delivers low impedance, elevated ripple-handling capability, and extended endurance at elevated temperatures, making it suitable for compact power designs and board-level power decoupling.

Key Features

• Capacitance and Voltage — 470 µF rated capacitance with a 10 V rated voltage and a capacitance tolerance of −20% to +20% for predictable bulk energy storage.
• Low Loss / Tan δ — tanδ of 0.19 measured at 20°C, 120 Hz, supporting low dissipation in power applications.
• Ripple Current Capability — Low-frequency ripple current 294.5 mA (120 Hz) and high-frequency ripple current 475 mA (200 kHz) to support smoothing in switching supplies and converters.
• Leakage Current — Specified leakage current of 141 µA, aiding in predictable bias behavior after voltage application.
• Thermal and Endurance — Operating temperature range −55°C to +105°C with a rated endurance of 3000 hours at 105°C for the φ8 case size.
• Compact Radial Package — Metal can radial-lead construction, size φ8 × 15 mm (L), lead spacing 3.5 mm (±0.5 mm), suitable for through-hole assembly in space-constrained layouts.
• RoHS Compliant & Production Ready — RoHS-compliant material set and listed as mass production with bulk and bag packing options (no terminal forming).

Typical Applications

• Switching Power Supplies — Low impedance and elevated ripple handling make it suitable for output filtering and bulk decoupling in switching regulators.
• Board-Level Power Filtering — Compact φ8×15 mm radial format provides bulk capacitance for local smoothing on power rails.
• General Purpose Electronics — Polarized aluminum electrolytic for general power-supply decoupling and energy storage in consumer and industrial designs.

Unique Advantages

• Low-Impedance Performance: Specified tanδ and series design characteristics support lower AC losses, helping reduce voltage ripple in power circuits.
• High Ripple Handling: Defined ripple current ratings at both low and high frequencies provide designers with quantifiable limits for thermal and ripple performance.
• Extended High‑Temperature Endurance: Rated for 3000 hours at 105°C for the φ8 case, offering longevity in thermally demanding applications.
• Compact Through‑Hole Form Factor: φ8 × 15 mm size with 3.5 mm lead spacing enables high-capacitance placement in constrained board areas while retaining through-hole mechanical robustness.
• predictable leakage and tolerance: Specified leakage current and ±20% capacitance tolerance simplify margin calculations during power system design.
• Regulatory Compliance & Production Support: RoHS compliance and mass-production availability streamline procurement and manufacturing integration.
