UVR2W2R2MPD

The UVR2W2R2MPD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UVR series. It provides 2.2 μF capacitance at a 450 V rating in a compact φ10 × 12.5 mm can with 5 mm lead spacing.

Designed for general-purpose use and standard entertainment electronics, this polarized capacitor offers a balance of high-voltage capability, compact footprint, and defined endurance for reliable power-supply filtering and smoothing tasks.

Key Features

• Capacitance & Tolerance — 2.2 μF nominal capacitance with tolerance of -20% to +20%, specified at 20°C, 120 Hz.
• High Voltage Rating — Rated voltage: 450 V for use in higher-voltage circuits.
• Loss Angle (tan δ) — tanδ (DF) 0.25 measured at 20°C, 120 Hz, providing a quantified dissipation factor for design verification.
• Ripple Current Performance — Low-frequency ripple current: 35 mA at 120 Hz; high-frequency ripple current: 56 mA at 10 kHz, enabling specification-driven selection for AC ripple handling.
• Leakage Current — Specified leakage current of 139 μA, useful for assessing standby and leakage loss in designs.
• Endurance & Temperature Range — Rated for 2000 hours at 85°C and an operating temperature range of -25°C to 85°C (450 V category).
• Form Factor & Mounting — Radial lead, polarized can with φ10 × 12.5 mm dimensions and 5 mm lead spacing (±0.5 mm); available bulk (no terminal forming) or bag packing.
• Compliance — RoHS compliant.

Typical Applications

• Entertainment Electronics — Power-supply filtering and smoothing in consumer audio/video and entertainment devices where the UVR series is commonly applied.
• General Power Circuits — DC-link, smoothing, and decoupling in higher-voltage general-purpose power supplies and converters.
• Standby and Bias Circuits — Low-leakage characteristics make it suitable for circuits where standby leakage needs to be controlled.

Unique Advantages

• High-voltage capability: 450 V rating supports applications requiring elevated voltage handling without increasing component count.
• Compact miniature can: φ10 × 12.5 mm package reduces board space compared with larger electrolytic options while maintaining rated performance.
• Measured ripple specs: Published low- and high-frequency ripple current values (35 mA at 120 Hz, 56 mA at 10 kHz) simplify thermal and ripple budgeting in designs.
• Defined endurance: 2000 hours at 85°C provides a clear reliability expectation for lifetime planning under rated stress.
• Controlled leakage: Specified leakage current of 139 μA helps designers quantify standby losses and bias stability.
• RoHS compliant and mass-production available: Suitable for volume procurement and regulatory-aligned designs.
