UHV1E332MHD

The UHV1E332MHD from Nichicon is a radial‑lead aluminum electrolytic capacitor in the UHV series designed for general‑purpose electronic designs that require high ripple handling and low impedance. It provides 3.3 mF (3300 µF) capacitance at a 25 V rating in a compact φ16×25L can, optimized for designs needing reliable bulk energy storage and smoothing over a wide temperature range.

Key Features

• High capacitance and rated voltage — 3.3 mF (3300 µF) nominal capacitance with a 25 V rated voltage and ±20% tolerance for bulk energy storage and decoupling.
• Low impedance — Specified impedance of 33 mΩ, supporting lower voltage ripple under AC conditions.
• High ripple current capability — Low frequency ripple current 2.9925 A at 120 Hz and high frequency ripple current 3.99 A at 100 kHz to support switch‑mode and high‑frequency applications.
• Electrical loss (tan δ) — Tangent of loss angle 0.17 measured at 20°C, 120 Hz, indicating dissipation characteristics for thermal and ripple assessments.
• Leakage current — Specified leakage current of 825 µA after rated voltage application (measurement condition noted in product data).
• Robust temperature and lifetime — Rated operating range −40°C to +105°C with an endurance of 6000 hours at 105°C.
• Radial lead package — φ16×25L can with 7.5 mm lead spacing (±0.5 mm tolerance) in radial lead form for through‑hole mounting; available in bulk or bag packing.
• Compliance — RoHS compliant.

Typical Applications

• Power supply filtering — Bulk smoothing and ripple reduction on 25 V rails where high ripple current and low impedance are required.
• DC‑DC converter output — Energy storage and decoupling for converters and regulators operating within the −40°C to +105°C range.
• General‑purpose electronic assemblies — Through‑hole radial mounting for industrial and consumer electronics that need reliable bulk capacitance and long endurance.

Unique Advantages

• High ripple tolerance: Rated ripple currents up to ~3.99 A (100 kHz) and ~2.99 A (120 Hz) reduce stress on the capacitor in high‑frequency environments.
• Compact footprint: φ16×25L packaging delivers 3300 µF in a small can (L: 2.5 cm × D: 1.6 cm), helping save board space while providing significant capacitance.
• Low impedance for better performance: 33 mΩ impedance helps minimize voltage drop and improve transient response on power rails.
• Long endurance at elevated temperature: 6000 hours at 105°C supports longer service life in designs that experience sustained thermal stress.
• Design‑friendly lead spacing: 7.5 mm lead spacing (±0.5 mm) and radial lead form simplify through‑hole assembly and prototyping.
• Regulatory conformity: RoHS compliance supports environmental and regulatory requirements.
