UVK2A3R3MDD

The UVK2A3R3MDD is a miniature aluminum electrolytic capacitor in a radial-lead, can-style package offering 3.3 µF capacitance at a 100 V rating. It is part of Nichicon’s UVK series, designed for compact, general-purpose electronic circuits that require a polarized high-voltage capacitor in a small footprint.

Key value comes from its compact φ5×11 mm can, defined electrical performance (tanδ, leakage, ripple current), and a rated lifetime of 2000 hours at 85°C—making it suitable where space efficiency and predictable performance are required.

Key Features

• Electrical Performance — 3.3 µF nominal capacitance with tolerance −20% to 20% and a 100 V rated voltage; designed as a polarized aluminum electrolytic capacitor.
• Loss Characteristics — tanδ of 0.08 (measured at 20°C, 120 Hz) for predictable dissipation in AC conditions at the specified measurement point.
• Leakage Current — Leakage current specified at 9.9 µA, supporting low standby leakage in polarized applications.
• Ripple Current Capability — Low-frequency ripple current 40 mA (120 Hz) and high-frequency ripple current 80 mA (10 kHz) to support a range of AC operating conditions.
• Reliability & Endurance — Rated for 2000 hours at 85°C with endurance criteria: capacitance change within ±20%, tanδ within 200% of initial spec, and leakage current ≤ initial specified value after test.
• Compact Package & Mounting — φ5×11 mm can with radial lead mounting, lead spacing 2.0 mm (±0.5 mm), available in bulk or bag packing for through-hole assemblies and manual handling.
• Operating Range & Compliance — Operating temperature −40°C to +85°C; RoHS compliant as part of the UVK series.

Typical Applications

• General-purpose electronic circuits — Provides polarized capacitance where a compact 3.3 µF / 100 V solution is required for general-purpose designs.
• Space-constrained designs — Miniature φ5×11 mm can and radial lead format suit compact PCBs and tight layout requirements.
• Through-hole assemblies and prototyping — Radial-lead package and bulk/bag packing facilitate manual assembly, replacement, and field service.

Unique Advantages

• Compact footprint for tight layouts: The φ5×11 mm can and 2.0 mm lead spacing reduce board area while retaining through-hole robustness.
• High-voltage capability in a small package: 100 V rating enables use in designs that require elevated DC voltage handling without increasing capacitor size substantially.
• Defined AC performance: Specified tanδ and ripple current values (40 mA at 120 Hz, 80 mA at 10 kHz) give designers measurable parameters for thermal and ripple budgeting.
• Endurance-backed reliability: 2000 hours at 85°C with clear endurance limits for capacitance, tanδ, and leakage supports predictable long-term behavior under rated stress.
• Regulatory compliance: RoHS conformity ensures the component meets common environmental directives for finished products.
• Easy inventory and serviceability: Radial lead form and standard packaging options (bulk / bag) simplify stocking and field replacement workflows.
