UVZ1H332MHD

The UVZ1H332MHD is a radial-lead aluminum electrolytic capacitor in Nichicon’s UVZ series, delivering 3.3 mF capacitance at a 50 V rating with a ±20% tolerance. It combines high capacitance in a compact φ18 × 35.5 mm can with performance characteristics targeted for general-purpose electronic power circuitry.

Engineered for extended operation across a wide temperature span (−55 °C to 105 °C) and rated for 2000 hours at 105 °C, this part supports designs that require reliable bulk energy storage and ripple current handling in a through-hole radial package.

Key Features

• Capacitance & Voltage — 3300 µF nominal capacitance with a 50 V rated voltage and tolerance of −20% to +20%, suitable for mid-voltage bulk storage and smoothing needs.
• Wide Temperature Range — Operating range from −55 °C to 105 °C, allowing use in applications with broad ambient temperature variation.
• Endurance — Specified life of 2000 hours at 105 °C under rated voltage, with capacitance change within ±20% after the endurance test.
• Ripple Current Capability — Low-frequency ripple current of 1.77 A at 120 Hz and high-frequency ripple current of 2.035 A at 10 kHz, supporting power supply smoothing across frequencies.
• Size & Mounting — Radial lead can package, dimensions φ18 × 35.5 mm and lead spacing 7.5 mm (±0.5 mm), for through-hole PCB mounting and straightforward assembly.
• Electrical Loss & Leakage — Dissipation factor (tan δ) of 0.16 at 20 °C, 120 Hz and a specified leakage current (per product data), enabling predictable ESR and standby characteristics.
• Compliance & Packing — RoHS compliant; available in bulk (no terminal forming) or bag packing to suit production handling preferences.

Typical Applications

• General-purpose power filtering — Bulk capacitance for smoothing and decoupling in power supplies where 3.3 mF at 50 V is required.
• Energy storage for intermediate rails — Local energy reservoir for converters and regulators operating within the specified voltage and temperature range.
• Industrial and commercial electronics — Through-hole radial mounting for assemblies that leverage robust, serviceable electrolytic capacitors in broad-temperature environments.

Unique Advantages

• High capacitance in a compact can — 3300 µF in a φ18 × 35.5 mm package provides significant bulk storage without large PCB footprint increases.
• Wide operating temperature window — −55 °C to 105 °C rating supports designs that must tolerate extreme cold and elevated operating temperatures.
• Documented endurance — 2000-hour life at 105 °C provides a clear reliability baseline for thermal stress planning and long-term performance expectations.
• Frequency-aware ripple handling — Specified ripple current values at 120 Hz and 10 kHz help engineers assess performance in both low- and high-frequency power environments.
• Standard radial-lead form factor — 7.5 mm lead spacing and common can dimensions simplify PCB layout and assembly for through-hole products.
• RoHS compliant — Conforms to RoHS requirements for regulatory compliance in many global markets.
