UVR2A2R2MDD

The UVR2A2R2MDD from Nichicon is a miniature aluminum electrolytic capacitor in the UVR standard series. It is a radial-lead, polarized capacitor with a nominal capacitance of 2.2 µF and a 100 V rated voltage, designed for general-purpose applications including entertainment electronics.

Key attributes include a compact φ5 × 11 mm can, a wide operating temperature range from −40 °C to +85 °C, and an endurance rating of 2000 hours at 85 °C. Status: End Of Life.

Key Features

• Capacitance & Voltage — 2.2 µF capacitance with a 100 V rated voltage suitable for higher-voltage general-purpose circuits.
• Compact Radial Package — Miniature radial can (φ5 × 11 mm) with 2.0 mm lead spacing (±0.5 mm), enabling space-efficient through-hole layouts.
• Temperature Range & Endurance — Rated for −40 °C to +85 °C with an endurance of 2000 hours at 85 °C to support stable operation in a range of environments.
• Ripple Performance — Low-frequency ripple current 30 mA at 120 Hz and high-frequency ripple current 60 mA at 10 kHz for filtering and decoupling tasks across frequencies.
• Leakage & Loss — Low leakage current of 6.6 µA and a tangent of loss angle (tan δ) of 0.20 (measured at 20 °C, 120 Hz) for predictable electrical behavior.
• Packaging Options — Supplied in bulk (no terminal forming) or bag packing for straightforward prototyping and assembly handling.
• RoHS Compliant — Conforms to RoHS requirements for environmentally compliant designs.

Typical Applications

• Consumer & Entertainment Electronics — Compact filtering and decoupling in audio, video and other entertainment equipment where small size and a 100 V rating are required.
• Power Supply Filtering — Bulk and high-frequency ripple suppression in through-hole power supply stages, leveraging specified ripple currents at 120 Hz and 10 kHz.
• General-Purpose Electronics — Decoupling and energy-storage tasks in compact assemblies that need a polarized electrolytic solution with proven endurance.

Unique Advantages

• High-voltage capability in a miniature footprint: 100 V rating combined with a φ5 × 11 mm package supports space-constrained designs that require elevated voltage handling.
• Balanced ripple performance: Defined low- and high-frequency ripple current ratings (30 mA at 120 Hz, 60 mA at 10 kHz) help designers dimension capacitors for both mains-frequency and high-frequency noise suppression.
• Predictable electrical characteristics: Specified tan δ (0.20 at 20 °C, 120 Hz) and low leakage current (6.6 µA) aid in selecting components for stable circuit behavior.
• Through-hole robustness: Radial lead mounting and 2.0 mm lead spacing with tolerance support reliable mechanical and electrical connections in conventional PCB designs.
• Endurance for sustained operation: 2000 hours at 85 °C provides a clear baseline for life-expectancy planning in thermal environments up to the rated category temperature.
• Regulatory compliance: RoHS compliance supports use in assemblies targeted for markets with restricted substances requirements.
