UVZ2W3R3MPD

The UVZ2W3R3MPD is a Nichicon UVZ-series aluminum electrolytic capacitor in a radial-lead can, offering 3.3 µF capacitance at a 450 V rated voltage. Designed for general-purpose applications, it delivers a combination of high-voltage capability, compact size (φ10 × 16 mm), and extended endurance for demanding ambient conditions.

Key attributes include a wide operating temperature range to 105°C, long endurance of 2000 hours at 105°C, and RoHS compliance, making it suitable for engineers specifying reliable, high-voltage electrolytic capacitance in through-hole designs.

Key Features

• High Voltage Rating — Rated voltage of 450 V to support high-voltage power circuits and energy storage requirements.
• Specified Capacitance & Tolerance — 3.3 µF nominal capacitance with ±20% tolerance measured at 120 Hz, 20°C.
• Loss Tangent (tan δ) — tan δ = 0.25 (measured at 120 Hz, 20°C, 450 V) for predictable AC loss behavior in design calculations.
• Ripple Current Performance — Low-frequency ripple current: 31 mA at 120 Hz; high-frequency ripple current: 49.6 mA at 10 kHz, enabling specification for both mains-frequency and higher-frequency ripple environments.
• Leakage Current — Specified leakage current of 159.4 µA, allowing designers to account for quiescent currents in power budgets.
• Wide Operating Temperature & Endurance — Rated for −25°C to +105°C with endurance of 2000 hours at 105°C under rated voltage.
• Compact Radial Package — φ10 × 16 mm can with 5 mm lead spacing (±0.5 mm) and radial lead mounting for through-hole PCB assemblies; available in bulk or bag packing.
• Regulatory — RoHS compliant.

Typical Applications

• General purpose power circuits — Suitable where a 450 V, 3.3 µF electrolytic capacitor is required for energy storage and decoupling in through-hole assemblies.
• High-voltage DC link or smoothing — Applicable to designs that require compact, high-voltage capacitance with defined ripple and leakage specifications.
• Industrial electronics — Use in industrial control and power supply modules operating up to 105°C and requiring long endurance (2000 h at 105°C).

Unique Advantages

• High-voltage capability: 450 V rating enables use in higher-voltage power rails without upsizing the capacitor.
• Compact radial can: φ10 × 16 mm footprint and 5 mm lead spacing allow tight PCB layouts and straightforward through-hole assembly.
• Measured ripple specifications: Provided low- and high-frequency ripple current values (31 mA @120 Hz, 49.6 mA @10 kHz) make it easier to specify thermal and lifetime margins.
• Endurance at elevated temperature: 2000 hours at 105°C under rated voltage supports reliable operation in hot ambient environments.
• Predictable leakage and loss: Specified leakage current (159.4 µA) and tan δ (0.25) assist in power budgeting and thermal analysis.
• RoHS compliant: Meets regulatory requirements for lead-free assemblies.
