UPW2A470MPD

The UPW2A470MPD is a Nichicon UPW series radial-lead aluminum electrolytic capacitor specified at 47 µF and 100 V. It is designed as a miniature, low-impedance, high-reliability capacitor suitable for power-electronics applications.

Key use cases include switching power supplies and automotive electronics where compact size, high-voltage capability and long endurance at elevated temperature are required. The device delivers measured low impedance and controlled loss (tanδ) for stable performance under DC bias and ripple conditions.

Key Features

• Capacitance & Tolerance — 47 µF nominal with tolerance of −20% to +20% (±20% at 120 Hz, 20 °C).
• Rated Voltage & Polarization — 100 V rated voltage; polarized aluminum electrolytic construction for DC power applications.
• Low Loss / Low Impedance — Tangent of loss angle (tanδ) 0.08 measured at 20 °C, 120 Hz; typical impedance 740 mΩ for improved ripple performance.
• Ripple Current Capability — Low-frequency ripple current 126 mA (120 Hz) and high-frequency ripple current 420 mA (10 kHz) to support switching and filtering tasks.
• Leakage Current — Specified leakage current 141 µA after rated voltage application at 20 °C.
• Endurance & Temperature Range — Rated lifetime 5000 hours at 105 °C; operating temperature range −55 °C to +105 °C.
• Compact Radial Package — φ10 × 16 mm can with radial leads and 5 mm lead spacing (±0.5 mm); available in bulk (no terminal forming) or bag packing.
• AEC-Q200 Rated — Supplied with AEC-Q200 rating for applications requiring industry-recognized component qualification.

Typical Applications

• Switching Power Supplies — Low impedance and defined ripple current ratings make this capacitor suitable for output and bulk filtering in switch-mode power supplies.
• Automotive Electronics — AEC-Q200 rating and 105 °C endurance support use in automotive electronic modules and control units.
• DC/DC Converters — 100 V rating and compact radial package are useful for high-voltage DC/DC stages and intermediate bus filtering.
• Industrial Power Modules — High-temperature endurance and controlled leakage current suit power conditioning and industrial power electronics.

Unique Advantages

• High-voltage capability in a small can — 100 V rating in a φ10 × 16 mm radial package enables compact designs that still require elevated voltage headroom.
• Measurable low-impedance performance — 740 mΩ impedance and tanδ of 0.08 (20 °C, 120 Hz) help minimize ripple and heat in power rails.
• Designed for long life at temperature — 5000 hours at 105 °C provides predictable end-of-life characteristics for thermal-stressed systems.
• Proven ripple-handling — Specified ripple currents at both low and high frequency (126 mA @120 Hz, 420 mA @10 kHz) support a range of switching frequencies.
• Automotive-grade qualification — AEC-Q200 rating makes it suitable where qualified passive components are required.
• Flexible handling and assembly — Radial-lead format with 5 mm lead spacing and bulk/bag packing options fits manual or automated assembly processes that accept radial components.
