UPS2W470MRD

The UPS2W470MRD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UPS series, designed as a miniature, low-impedance option for switching power supplies and general-purpose high-voltage circuits. It provides 47 µF capacitance at a 450 V rated voltage in a compact φ20 × 40 mm can with 10 mm lead spacing.

Engineered for demanding power applications, the part combines a high-voltage rating, defined ripple-current capability, and endurance at elevated temperature to support reliable operation in industrial and power-electronics designs.

Key Features

• Capacitance & Voltage: 47 µF capacitance rated at 450 V, suitable for high-voltage energy storage and smoothing in compact radial-can form.
• Low Impedance Design: Part of Nichicon’s UPS series described as miniature sized, low impedance, for switching power supplies, delivering performance targeted at power-conversion applications.
• Ripple Current Ratings: Low-frequency ripple current 175 mA at 120 Hz and high-frequency ripple current 280 mA at 10 kHz, enabling predictable behavior across common power-supply frequencies.
• Loss Angle (tan δ): tan δ = 0.25 measured at 20°C, 120 Hz, providing a specified dissipation characteristic for thermal and impedance planning.
• Endurance & Temperature Range: Rated life of 3000 hours at 105°C with an operating temperature range of −25°C to 105°C for sustained elevated-temperature performance.
• Packaging & Mounting: Radial lead mounting in a φ20 × 40 mm can with 10 mm lead spacing. Available in Bulk (no terminal forming) or Bag packing for through-hole assembly and prototyping.
• Leakage Current: Specified leakage current of 946 µA, useful for power-budget and standby-loss calculations.
• RoHS Compliance: Conforms to RoHS requirements, supporting regulatory compliance in supplied assemblies.

Typical Applications

• Switching Power Supplies: Low-impedance, miniature form factor suited for output smoothing and energy storage in switching regulators and power modules.
• High-Voltage General-Purpose Circuits: 450 V rating and 47 µF capacity make it appropriate for high-voltage DC applications requiring compact bulk capacitance.
• Industrial Power Electronics: Endurance of 3000 hours at 105°C and defined ripple ratings support continuous operation in industrial power systems.

Unique Advantages

• High Voltage Capability: 450 V rating allows use in higher-voltage topologies without upsizing the component footprint.
• Compact Radial Can: φ20 × 40 mm package with 10 mm lead spacing provides a space-efficient through-hole solution for PCB implementations.
• Predictable Ripple Performance: Specified ripple currents at both 120 Hz and 10 kHz let designers size thermal management and filter stages accurately.
• Specified Endurance at Elevated Temperature: 3000-hour life at 105°C gives a measurable reliability baseline for long-term power applications.
• Clear Electrical Parameters: Defined tan δ, leakage current, and tolerance (−20% to +20%) provide the electrical transparency needed for precise circuit design.
• Regulatory Readiness: RoHS compliance simplifies integration into assemblies that require restricted-substance conformity.
