UPW2A470MPD6

The UPW2A470MPD6 is a radial-lead aluminum electrolytic capacitor from Nichicon's UPW series, offering 47 µF capacitance at a 100 V rating. It is a miniature, low-impedance can-style capacitor engineered for power filtering in switching power supplies and other through-hole power designs.

Designed for demanding environments, this part combines a wide operating temperature range (−55°C to 105°C) with a rated endurance of 3000 hours at 105°C, making it suitable for industrial and automotive electronics that require stable power decoupling and ripple suppression.

Key Features

• Capacitance & Voltage — 47 µF nominal capacitance with a 100 V rated voltage and tolerance of −20% to +20% (measured at 120 Hz, 20°C).
• Low Dissipation Factor — tanδ = 0.08 (measured at 20°C, 120 Hz, 100 V) for reduced loss in AC conditions.
• Ripple Current Performance — Low-frequency ripple current 126 mA at 120 Hz and high-frequency ripple current 420 mA at 10 kHz, supporting effective smoothing of switching noise.
• Leakage Current — Specified leakage current of 141 µA (after rated voltage application), enabling predictable idle behavior.
• Temperature & Endurance — Rated for −55°C to 105°C with a lifetime of 3000 hours at 105°C under rated conditions.
• Compact Radial Package — φ8 × 20 mm can with 3.5 mm lead spacing and radial leads; available in bulk or bag packing. Includes pressure relief vent for safety under fault conditions.
• Low Impedance — Specified impedance of 740 mΩ for reduced voltage ripple and improved transient response in power circuits.
• AEC-Q200 Qualified — Designed and rated to AEC-Q200 standard as part of the UPW series for applications requiring automotive-grade qualification.

Typical Applications

• Switching Power Supplies — Output and bulk filtering to reduce voltage ripple and stabilize DC rails in switching converters.
• Automotive Electronics — Power filtering and decoupling in automotive modules where AEC-Q200 qualification and wide temperature range are required.
• Through-Hole Power Designs — General-purpose power supply smoothing and energy storage in radial through-hole assemblies and retrofit designs.

Unique Advantages

• Compact, low-impedance package: φ8 × 20 mm can and 740 mΩ impedance deliver effective filtering in space-constrained assemblies.
• High voltage capability: 100 V rating enables use on higher-voltage rails without series stacking.
• Predictable ripple handling: Specified LF and HF ripple currents (126 mA at 120 Hz, 420 mA at 10 kHz) allow designers to size capacitors for both mains-frequency and switching-frequency ripple.
• Wide temperature range and endurance: −55°C to 105°C operation with 3000 hours life at 105°C supports long-term stability in thermal stress environments.
• Automotive-grade qualification: AEC-Q200 rating provides a verifiable qualification path for vehicle electronics and related systems.
• Radial lead convenience: Standard lead spacing (3.5 mm) and bulk/bag packaging simplify through-hole PCB assembly and stocking.

Why Choose UPW2A470MPD6?

The UPW2A470MPD6 pairs a high 100 V rating with a compact radial-can footprint and low impedance, delivering reliable power-filtering performance where board space and thermal endurance matter. Its AEC-Q200 qualification and 3000-hour rating at 105°C make it appropriate for designs that require proven stability across wide temperatures and sustained stress.

This capacitor is well suited to engineers designing switching power supplies, automotive modules, and through-hole power assemblies who need a verifiable spec set for capacitance, dissipation factor, ripple current, leakage, and lifetime.
