UVR2E331MRD

The UVR2E331MRD is a 330 µF, 250 V polarized aluminum electrolytic capacitor from Nichicon’s UVR miniature standard series. It is a radial-lead can designed for general-purpose and entertainment electronics, offering bulk capacitance in a compact φ22 × 50 mm package.

Engineered for power filtering and energy-storage tasks, this capacitor provides defined ripple-current capability and endurance ratings for designs that require stable performance across –40°C to 85°C.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance rated at 250 V, with a tolerance of ±20% at 120 Hz, 20°C.
• Radial Lead Package — Radial, can-style package with 10 mm lead spacing (±0.5 mm) for through-hole mounting and easy handling in assembly.
• Ripple Current Handling — Low-frequency ripple current of 1.17 A at 120 Hz and high-frequency ripple current of 1.345 A at 10 kHz, suitable for smoothing and filtering duties.
• Loss Characteristics — Dissipation factor (tan δ) of 0.2 measured at 20°C, 120 Hz, supporting predictable AC loss behavior in designs.
• Leakage Current — Specified leakage current of 3400 µA following rated-voltage application at 20°C.
• Endurance — Rated for 2000 hours at 85°C with defined limits on capacitance change, tan δ, and leakage current after the endurance test.
• Operating Temperature — Specified operating range from –40°C to +85°C to cover a wide span of ambient conditions.
• Packaging Options — Supplied in bulk (no terminal forming) or bag packing to suit different production workflows.
• RoHS Compliance — Compliant with RoHS requirements.

Typical Applications

• Entertainment Electronics — Ideal for power filtering and bulk energy storage in consumer audio/video and other entertainment equipment, consistent with the UVR series positioning.
• Power Supply Smoothing — Used for smoothing and decoupling in linear and switching power supplies where 250 V capability and substantial capacitance are required.
• General-Purpose Electronics — Suitable for general-purpose boards and modules that need a compact radial electrolytic with defined ripple-current and endurance characteristics.

Unique Advantages

• Compact Miniature Can — φ22 × 50 mm package delivers 330 µF capacitance in a small footprint for space-constrained through-hole assemblies.
• Measured Ripple Ratings — Specified ripple-current values at both 120 Hz and 10 kHz allow designers to evaluate performance across expected operating frequencies.
• Proven Endurance — 2000 hours at 85°C endurance rating provides a measurable reliability baseline for thermal and lifetime planning.
• Clear Electrical Limits — Defined tan δ and leakage current specifications simplify thermal and leakage budget calculations in power designs.
• Versatile Mounting — Radial lead form with standard 10 mm spacing supports straightforward through-hole integration and replacement in legacy layouts.
• Compliance and Packaging Flexibility — RoHS compliance and bulk or bag packing options support manufacturing and environmental requirements.
