UPW2W470MRD

The UPW2W470MRD is a Nichicon UPW-series miniature aluminum electrolytic capacitor in a radial-lead can. It provides 47 µF of capacitance at a rated voltage of 450 V and is optimized for low impedance and reliable long-term operation.

Engineered for switching power supplies and automotive power subsystems, this radial through-hole capacitor combines compact φ20 × 40 mm packaging and AEC-Q200 qualification with ripple-current capability and an 8000-hour endurance at 105°C.

Key Features

• Capacitance & Voltage — 47 µF nominal capacitance with a 450 V rated voltage and ±20% tolerance for high-voltage smoothing and energy storage.
• Reliability & Endurance — Qualified UPW series design with a rated lifetime of 8000 hours at 105°C under rated conditions, supporting long-term high-temperature operation.
• Ripple and Low-Impedance Performance — Specified ripple currents of 175 mA at 120 Hz (low frequency) and 280 mA at 10 kHz (high frequency) for effective filtering in switching circuits.
• AEC-Q200 Qualification — AEC-rated construction for designs targeting automotive and demanding environments.
• Electrical Characteristics — Dissipation factor (tan δ) of 0.25 measured at 20°C, 120 Hz, 450 V; leakage current listed at 946 µA.
• Package & Mounting — Radial lead, can-type package with φ20 × 40 mm dimensions and 10 mm lead spacing (±0.5 mm), supplied in bulk/bag packing for through-hole assembly.
• Operating Temperature — Specified operating range from −25°C to 105°C for use in elevated-temperature power applications.

Typical Applications

• Switching Power Supplies — Low-impedance UPW construction and specified ripple current make the part suitable for output smoothing and bulk filtering in high-voltage switch-mode supplies.
• Automotive Power Systems — AEC-Q200 rating and 8000-hour endurance at 105°C support deployment in automotive electronic power subsystems where thermal and reliability demands are high.
• High-Temperature Power Modules — Compact high-voltage capacitance with a −25°C to 105°C operating range and long-life specification for high-temperature power electronics environments.

Unique Advantages

• High-voltage capability: 450 V rating enables direct use in high-voltage DC link and smoothing applications without additional series components.
• Long-term thermal endurance: 8000 hours at 105°C provides predictable life performance for designs exposed to sustained elevated temperatures.
• Automotive-grade qualification: AEC-Q200 rating supports use in automotive and similarly demanding sectors that require standardized qualification.
• Measured ripple performance: Specified ripple currents at both low and high frequencies (175 mA at 120 Hz, 280 mA at 10 kHz) help designers size capacitive filtering for real-world switching loads.
• Compact radial form factor: φ20 × 40 mm can with 10 mm lead spacing for straightforward through-hole mounting and PCB layout integration.
• Defined electrical loss and leakage: Dissipation factor (tan δ) 0.25 and leakage current 946 µA provide clear electrical parameters for circuit-level thermal and standby current budgeting.
