UHW0J332MPD

The UHW0J332MPD is a radial-lead aluminum electrolytic capacitor in Nichicon’s UHW series, offering a 3300 µF capacitance at a 6.3 V rating. It combines a compact φ10 × 25 mm can with high ripple-current capability and low impedance for general-purpose power applications.

Designed for through-hole mounting, this device targets general-purpose power filtering, smoothing and energy-storage roles where long endurance and high-frequency performance are required.

Key Features

• Capacitance & Voltage — 3300 µF (3.3 mF) nominal capacitance with a rated voltage of 6.3 V and tolerance of −20% to +20%.
• High Ripple Current — Low-frequency ripple current of 2.175 A (120 Hz) and high-frequency ripple current of 2.9 A (10 kHz), enabling effective filtering under heavy AC ripple conditions.
• Low Impedance — Specified impedance of 51 mΩ supports high-current decoupling and reduces voltage drop under load.
• Loss Characteristics — Tangent of loss angle (tan δ) specified at 0.25 measured at 20°C, 120 Hz, for predictable dissipation behavior.
• Long Endurance — Rated for 10,000 hours at 105°C, supporting reliable operation in elevated-temperature environments.
• Temperature Range — Operates from −40°C to +105°C, suitable for a wide range of ambient conditions.
• Radial Through‑Hole Package — φ10 × 25L can with 5 mm lead spacing (±0.5 mm), 0.6 mm lead diameter, supplied in bulk or bag packing for assembly flexibility.
• Leakage Current — Specified leakage current of 207.9 µA, measured after standard application of rated voltage conditions.
• RoHS Compliant — Meets RoHS requirements for restricted substances.

Typical Applications

• Power Supply Filtering — Use where smoothing of DC rails is required; high ripple-current ratings and low impedance help maintain stable bus voltages under load.
• Decoupling in Embedded Power Systems — Provides bulk energy storage and transient suppression for general-purpose embedded electronics operating within −40°C to +105°C.
• Energy Reservoir for Power Converters — Compact φ10 × 25 mm size with elevated ripple capability supports converters and regulators that require local bulk capacitance.

Unique Advantages

• High Ripple-Current Handling: 2.175 A (120 Hz) and 2.9 A (10 kHz) ratings reduce thermal stress and improve reliability in ripple-rich circuits.
• Low Impedance: 51 mΩ impedance supports efficient current delivery and lower voltage excursions during switching transients.
• Compact Through-Hole Form Factor: φ10 × 25L can and 5 mm lead spacing provide a small footprint for space-constrained PCB designs while retaining through-hole mechanical robustness.
• Extended Endurance at Elevated Temperature: 10,000 hours at 105°C offers longevity for designs exposed to sustained high operating temperatures.
• Predictable Dissipation: Specified tan δ (0.25 at 20°C, 120 Hz) and leakage current figures enable straightforward thermal and leakage budgeting in system design.
