UVK2W330MHD

The UVK2W330MHD is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon's UVK series, specified for general-purpose high-voltage applications. It delivers 33 µF capacitance at a 450 V rating in a compact φ16 × 25 mm can with 7.5 mm lead spacing, providing high-voltage smoothing and decoupling where space and voltage capability are required.

Designed for reliable operation across a broad operating range (−25°C to +85°C) with a rated endurance of 2000 hours at 85°C, this RoHS-compliant part is available in bulk or bag packing for production use.

Key Features

• High Voltage Rating — Rated voltage: 450 V, enabling use in high-voltage smoothing and filtering applications.
• Compact Miniature Package — φ16 × 25 mm can with radial lead mounting and 7.5 mm lead spacing (±0.5 mm), offering space-efficient placement on through‑hole boards.
• Capacitance and Tolerance — 33 µF capacitance with tolerance of −20% to +20% for predictable energy storage.
• Thermal and Endurance Specification — Operating temperature range −25°C to +85°C and rated for 2000 hours at 85°C per endurance specification.
• Loss and Leakage Characteristics — Tangent of loss angle (tan δ) specified at 0.25 (measured at 20°C, 120 Hz) and a measured leakage current of 694 µA for this part.
• Ripple Current Capability — Low-frequency ripple current 180 mA at 120 Hz and high-frequency ripple current 288 mA at 10 kHz, supporting smoothing in both line‑frequency and switching environments.
• Polarized, Through-Hole Mount — Radial lead, polarized design suited for standard through‑hole assembly and bulk/bag packing for production workflows.
• RoHS Compliance — Compliant with RoHS requirements for restricted substances.

Typical Applications

• High-Voltage Power Supplies — Bulk smoothing and decoupling where 450 V rating and compact size are required.
• Switching Power Electronics — Energy storage and ripple suppression for circuits operating with high-frequency switching, supported by 10 kHz ripple current spec.
• Industrial Equipment — General-purpose filtering in industrial control and power conversion systems within the specified temperature and endurance limits.

Unique Advantages

• High-Voltage Capability: 450 V rating enables use in higher-voltage circuits without upsizing the capacitor.
• Space-Efficient Miniature Can: φ16 × 25 mm package reduces board footprint while preserving required capacitance.
• Proven Endurance: Rated 2000 hours at 85°C gives clear lifecycle expectations for thermal stress conditions.
• Defined Ripple Performance: Provided ripple current data at both 120 Hz and 10 kHz helps designers size thermal and ripple handling in both line- and switching-frequency designs.
• Production-Ready Packaging: Available in bulk (no terminal forming) or bag packing to suit assembly and inventory workflows.
• Regulatory Compliance: RoHS-compliant construction supports regulatory requirements for restricted substances.

Why Choose UVK2W330MHD?
