UHW1V331MPD

The UHW1V331MPD is a Nichicon UHW series miniature aluminum electrolytic capacitor in a radial‑lead can designed for general‑purpose applications. It delivers 330 µF at a 35 V rating in a compact φ10 × 12.5 mm package with a 5 mm lead spacing.

Designed for high ripple environments and long operational life, this high‑reliability type combines low impedance and elevated ripple handling with an extended endurance rating to support compact power and decoupling circuits across a range of operating temperatures.

Key Features

• Capacitance and Voltage: 330 µF nominal capacitance with a 35 V rated voltage and a tolerance of −20% to +20% for predictable energy storage.
• Low impedance: Specified impedance of 150 mΩ and datasheet‑level design for lower impedance at high frequency, aiding high‑frequency decoupling.
• High ripple current capability: Rated ripple currents of 850 mA at 120 Hz and 1.7 A at 10 kHz to support high ripple environments.
• Loss characteristics: Tan δ (DF) of 0.11 measured at 20°C, 120 Hz, providing a known dissipation profile for thermal and circuit design.
• Long endurance: Life rating of 10,000 hours at 105°C to support sustained operation in elevated temperature applications.
• Wide operating temperature: −40°C to +105°C operating range for use across varied thermal environments.
• Compact radial package: φ10 × 12.5 mm can with 5 mm lead spacing (±0.5 mm) in a radial‑lead mounting style for through‑hole assemblies.
• Leakage current: Specified leakage current of 115.5 µA after standard test conditions.
• Environmental compliance and packing: RoHS‑compliant; available in bulk (no terminal forming) or bag packing.

Typical Applications

• General‑purpose power filtering: Compact smoothing and decoupling tasks where 330 µF and 35 V rating provide bulk energy storage and noise reduction.
• High‑ripple circuits: Circuits that require elevated ripple handling—benefit from the specified 850 mA (120 Hz) and 1.7 A (10 kHz) ripple currents.
• Through‑hole industrial and board‑level assemblies: Radial‑lead can package with 5 mm lead spacing fits typical through‑hole layouts for power and control boards.

Unique Advantages

• Compact energy density: 330 µF in a φ10 × 12.5 mm can lets designers save board area while retaining useful capacitance and voltage headroom.
• High ripple tolerance: Defined low‑ and high‑frequency ripple current ratings reduce the need for parallel components in many designs.
• Predictable dissipation: Specified tan δ (0.11 at 20°C, 120 Hz) and leakage current (115.5 µA) enable accurate thermal and leakage budgeting.
• Long operational life: 10,000 hours at 105°C supports designs intended for extended service intervals and sustained elevated temperatures.
• Radial‑lead convenience: Through‑hole mounting and standard 5 mm lead spacing simplify assembly for legacy and robust PCB designs.
• Regulatory compliance: RoHS‑compliant construction simplifies inclusion in regulated product lines.
