UHW1A332MHD

The UHW1A332MHD is a miniature, high-reliability aluminum electrolytic capacitor in a radial lead can. It provides 3.3 mF (3300 µF) capacitance at a 10 V rating in a compact φ12.5 × 20 mm package with 5 mm lead spacing.

Designed for general-purpose electronic applications, this Nichicon UHW series unit delivers low impedance and elevated ripple-current capability with a long endurance of 10,000 hours at 105°C, making it suitable for designs that require compact power storage with proven thermal and electrical stability.

Key Features

• Capacitance & Voltage — 3.3 mF (3300 µF) rated at 10 V with a capacitance tolerance of −20% to +20% for predictable sizing in designs.
• Radial Lead Package — Miniature radial, can-style package (φ12.5 × 20 mm) with 5 mm lead spacing (±0.5 mm) for through-hole mounting and compact board layouts.
• High Ripple Current — Low-frequency ripple current of 1.95 A at 120 Hz and high-frequency ripple current of 2.6 A at 10 kHz to support power-supply filtering and dynamic loads.
• Low Impedance — Rated impedance of 51 mΩ helps reduce voltage drop under ripple and transient conditions; series-level notes indicate lower impedance at high frequency ranges.
• Loss Angle (tan δ) — tan δ = 0.22 measured at 20°C, 120 Hz with 10 V applied, providing a defined dissipation characteristic for thermal and loss budgeting.
• Leakage & Endurance — Leakage current specified at 330 µA and rated endurance of 10,000 hours at 105°C under standard test conditions for long-term reliability.
• Operating Range & Compliance — Operational temperature range −40°C to +105°C; RoHS-compliant construction.
• Packaging & Availability — Available in bulk (no terminal forming) or bag packing; product status: mass production.

Typical Applications

• General-purpose electronic equipment — Provides bulk capacitance and energy storage for a wide range of circuits that specify a compact 3.3 mF / 10 V electrolytic solution.
• Power supply modules — Suited for localized filtering where 1.95 A (120 Hz) and 2.6 A (10 kHz) ripple-current capability and low impedance are required in a small radial package.
• Thermally demanding environments — Rated for −40°C to +105°C and 10,000 hours at 105°C, appropriate for equipment designs with extended high-temperature endurance requirements.

Unique Advantages

• Compact high-capacitance form factor: Delivers 3.3 mF in a φ12.5 × 20 mm can, enabling significant bulk capacitance in space-constrained layouts.
• High ripple handling: Specified ripple-current ratings at low and high frequencies (1.95 A and 2.6 A) allow the capacitor to manage AC stress from power-supply and switching environments.
• Defined electrical losses: Specified tan δ (0.22 at 20°C, 120 Hz, 10 V) and low impedance (51 mΩ) provide clear parameters for thermal and noise-performance calculations.
• Long endurance at elevated temperature: 10,000-hour life at 105°C supports designs that require sustained performance under thermal stress.
• Through-hole radial mounting: Ease of placement and mechanical robustness for assemblies that prefer radial lead components.
• Regulatory compliance: RoHS-compliant construction for designs targeting restricted-substance conformity.
