UPW2D331MRD

The UPW2D331MRD is a radial-lead aluminum electrolytic capacitor in Nichicon’s UPW series, designed for miniature, low-impedance, high-reliability power applications. This 330 µF, 200 V polarized capacitor provides energy buffering and smoothing for higher-voltage power rails and switching power supplies.

Engineered for continuous operation up to 105°C with long endurance, the part is suited to applications that require sustained ripple performance and stable electrical characteristics across temperature.

Key Features

• Capacitance & Tolerance — 330 µF nominal with tolerance of -20% to +20%.
• Rated Voltage — 200 V DC rating for higher-voltage power rails and filtering duties.
• Low-loss Performance — tanδ 0.15 measured at 20°C, 120 Hz for controlled dissipation.
• Ripple Current Capability — 1.10 A at 120 Hz (low frequency) and 1.265 A at 10 kHz (high frequency) to support AC ripple handling in power converters.
• Leakage Current — Specified leakage current of 2740 µA.
• Long Endurance — Rated life of 8000 hours at 105°C.
• Operating Temperature — -40°C to 105°C for broad thermal operating range.
• Form Factor — Radial lead can, size φ22 × 40 mm (D × L) with 10 mm lead spacing (±0.5 mm).
• Packaging — Available in bulk (no terminal forming) or bag packing for flexible procurement and handling.
• AEC Qualification — AEC-Q200 rating noted in specifications.

Typical Applications

• Switching Power Supplies — Use for input/output smoothing and energy storage where a compact, low-impedance capacitor is required.
• Higher-Voltage Power Rails — 200 V rating supports filtering and decoupling on elevated DC bus voltages.
• Automotive Electronics — Applicable to automotive modules that utilize AEC-Q200–rated passive components for reliability in elevated-temperature environments.

Unique Advantages

• High-voltage capability: 200 V rating enables use on elevated DC rails without series stacking.
• Designed for sustained operation: 8000 hours at 105°C offers long-term endurance for continuous-duty applications.
• Effective ripple handling: Specified ripple currents at 120 Hz and 10 kHz indicate the part’s ability to manage both low- and high-frequency AC components.
• Compact radial form: φ22 × 40 mm can size with 10 mm lead spacing provides straightforward through-hole mounting and mechanical robustness.
• Automotive-grade qualification: Inclusion of AEC-Q200 supports selection for designs targeting automotive reliability requirements.
• Flexible supply formats: Offered in bulk or bag packing to match assembly and procurement preferences.
