UVR2A3R3MDD

The UVR2A3R3MDD is a miniature aluminum electrolytic capacitor in a radial-lead can, offering 3.3 µF capacitance at a 100 V rated voltage. It is part of Nichicon’s UVR series, a standard lineup developed for entertainment electronics and general-purpose applications.

Designed for compact through-hole designs, this polarized capacitor delivers moderate ripple-handling capability, low leakage, and a defined endurance rating for reliable operation across a broad temperature range.

Key Features

• Capacitance & Voltage — 3.3 µF nominal capacitance with a rated voltage of 100 V and a capacitance tolerance of -20% to +20%.
• Low Loss Characteristics — Tangent of loss angle (tan δ) specified at 0.08 (measured at 20°C, 120 Hz), supporting predictable dissipation for filtering and decoupling tasks.
• Ripple Current Performance — Low-frequency ripple current of 40 mA (120 Hz) and high-frequency ripple current of 80 mA (10 kHz), suitable for modest AC ripple filtering in power rails.
• Leakage Current — Specified leakage current of 9.9 µA, helping minimize standby losses and leakage-related drift in long-running circuits.
• Temperature & Endurance — Rated operating range from -40°C to +85°C with an endurance specification of 2000 hours at 85°C under rated voltage.
• Compact Radial Package — Small φ5 × 11 mm can (approx. D: 0.5 cm × L: 1.1 cm) with 2 mm lead spacing (±0.5 mm), supplied bulk or bag packed for through-hole assembly.
• Polarized, General-Purpose — Polarized aluminum electrolytic suited for general-purpose applications requiring a compact radial lead capacitor.
• RoHS Compliant — Conforms to RoHS directive requirements as noted for the UVR series.

Typical Applications

• Consumer Entertainment Electronics — Compact power supply smoothing and decoupling in audio/video equipment where the UVR series is specified for standard entertainment products.
• General-Purpose Power Filtering — Through-hole power rail decoupling and ripple suppression in small PCB footprints using radial leads.
• Control and Interface Circuits — Local energy storage and smoothing for control boards and peripheral interface modules operating up to 100 V.

Unique Advantages

• Small footprint for through-hole designs — φ5 × 11 mm can and narrow 2 mm lead spacing reduce board area for radial-mounted components.
• Defined endurance rating — 2000 hours at 85°C under rated voltage provides a measurable reliability baseline for product design and qualification.
• Balanced ripple handling — Specified low- and high-frequency ripple currents (40 mA @120 Hz, 80 mA @10 kHz) support mixed-frequency filtering needs.
• Low leakage — 9.9 µA leakage current helps limit standby losses and leakage-related performance changes over time.
• Clear loss-angle specification — tan δ = 0.08 at 20°C, 120 Hz gives designers predictable ESR-related behavior for AC and transient conditions.
• RoHS compliance — Conforms to RoHS, supporting regulatory requirements for lead-free assemblies.
