UVR2W330MHD

The UVR2W330MHD is a Nichicon UVR-series aluminum electrolytic capacitor in a radial-lead can, rated at 33 µF and 450 V. It is designed for general-purpose, high-voltage through-hole applications where compact, polarized bulk capacitance is required.

With a 2000-hour endurance at 85°C, measured ripple-current specifications at both low and high frequencies, and RoHS compliance, this part is positioned for designs that need verified high-voltage performance and reliable lifetime characteristics.

Key Features

• Rated Capacitance and Voltage — 33 µF capacitance at a 450 V rating provides polarized bulk capacitance for high-voltage DC circuits.
• Loss Characteristics — tanδ = 0.25 measured at 20°C, 120 Hz, enabling designers to assess dissipation for thermal and filtering calculations.
• Ripple Current Ratings — Low-frequency ripple current 230 mA at 120 Hz and high-frequency ripple current 368 mA at 10 kHz, specified for both LF and HF performance considerations.
• Leakage Current — Specified leakage current of 694 µA, useful for bias and standby current budgeting.
• Endurance — 2000 hours at 85°C with specified limits for capacitance change, tanδ and leakage current after the endurance test.
• Operating Temperature Range — Rated for −25°C to +85°C (appropriate for the 450 V variant in the UVR series).
• Radial Through‑Hole Package — φ16 × 35.5 mm can with 7.5 mm lead spacing (±0.5 mm) and radial leads for easy insertion and secure soldering in through-hole assemblies.
• Packaging Options & Production Status — Available in bulk (no terminal forming) or bag packing; part is in mass production and RoHS compliant.

Typical Applications

• High‑voltage DC filtering — 450 V rating and 33 µF capacitance make this capacitor suitable for bulk filtering on high-voltage DC rails.
• Power supply smoothing — Radial-lead form and defined ripple current specs support smoothing and energy storage in general-purpose power supplies.
• Consumer entertainment electronics — Part of the UVR miniature series commonly used in entertainment electronics where compact high-voltage capacitance is needed.
• Prototyping and repair — Through-hole radial package and standard lead spacing simplify replacement and board-level prototyping.

Unique Advantages

• High-voltage capability: 450 V rating enables use in higher-voltage circuit sections without the need for series stacking.
• Measured LF and HF ripple performance: Specified ripple currents at 120 Hz and 10 kHz allow direct comparison for both mains-frequency and switching-frequency designs.
• Verified endurance at elevated temperature: 2000 hours at 85°C gives a documented baseline for lifetime planning under thermal stress.
• Through-hole robustness: Radial-lead, canned package with 7.5 mm lead spacing (±0.5 mm) provides mechanical stability for through-hole assemblies.
• Predictable electrical losses: tanδ specified at 0.25 (20°C, 120 Hz) supports thermal and dissipation calculations during design.
• Regulatory compliance: RoHS compliant for use in environments with restricted hazardous substances requirements.
