UVZ2E331MRD

The UVZ2E331MRD is a radial‑lead aluminum electrolytic capacitor from Nichicon’s UVZ series. It offers a 330 µF capacitance at a 250 V rating in a compact φ22 × 50 mm can with 10 mm lead spacing and is intended for general-purpose applications.

Designed for use across a wide operating temperature range (−40 °C to 105 °C) and specified for 2000 hours endurance at 105 °C, this capacitor provides quantifiable performance data for engineers specifying bulk energy storage, decoupling or filtering components where clear electrical and thermal limits are required.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a 250 V rated voltage and capacitance tolerance of −20% to +20%.
• Temperature Range — Rated for operation from −40 °C to 105 °C, enabling use across broad ambient conditions.
• Endurance — Life rating of 2000 hours at 105 °C with specified limits for capacitance change and dissipation factor after test.
• Ripple Current Performance — Low‑frequency ripple current 730 mA at 120 Hz and high‑frequency ripple current 839.5 mA at 10 kHz, allowing quantifiable ripple handling in power circuits.
• Electrical Loss — Tangent of loss angle (tan δ) of 0.20 measured at 20 °C and 120 Hz for this rated voltage and capacitance.
• Leakage Current — Specified leakage current of 3400 µA for defined initial conditions.
• Package & Mounting — Radial lead (can) construction, size φ22 × 50 mm (height 50 mm), lead spacing 10 mm; available in bulk (no terminal forming) or bag packing.
• RoHS Compliant — Conforms to RoHS directive requirements as indicated in the UVZ series documentation.

Typical Applications

• General‑purpose power supplies — A 250 V rating and 330 µF capacitance support bulk filtering and energy storage where these electrical limits are required.
• Industrial electronics — Specified ripple currents at 120 Hz and 10 kHz and a −40 °C to 105 °C operating range suit designs with defined thermal and ripple load profiles.
• Chassis‑mounted assemblies — Radial lead can package (φ22 × 50 mm) and 10 mm lead spacing for through‑hole mounting in conventional power modules and controllers.

Unique Advantages

• Quantified endurance specification — 2000 hours at 105 °C provides a measurable life parameter for thermal stress planning and maintenance schedules.
• Clear ripple‑handling data — Published low‑ and high‑frequency ripple currents let designers size capacitors against measured ripple loads rather than estimate performance.
• Wide usable temperature window — −40 °C to 105 °C operation enables deployment across varied ambient conditions with known limits.
• Compact radial can format — φ22 × 50 mm density with standard 10 mm lead spacing simplifies mechanical integration into through‑hole boards and power assemblies.
• RoHS compliance — Meets regulatory material restrictions called out in the UVZ series documentation, supporting compliance-driven designs.
