UVK2A2R2MDD

The UVK2A2R2MDD is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon's UVK series. It delivers 2.2 µF capacitance with a 100 V rating in a compact φ5 × 11 mm can, making it suited to space‑constrained, through‑hole assemblies requiring a polarized electrolytic capacitor.

Key electrical characteristics include a loss tangent (tanδ) of 0.08 (measured at 20°C, 120 Hz), low- and high-frequency ripple current ratings (30 mA at 120 Hz and 60 mA at 10 kHz), and a specified leakage current of 6.6 µA. The device is rated for operation from −40°C to +85°C with an endurance of 2000 hours at 85°C.

Key Features

• Electrical Performance — 2.2 µF capacitance at 100 V rated voltage with capacitance tolerance of −20% to +20%.
• Low Loss (tanδ) — tanδ = 0.08 at 20°C, 120 Hz, supporting stable AC characteristics in filter and decoupling roles.
• Ripple Current Ratings — Low-frequency ripple current 30 mA (120 Hz) and high-frequency ripple current 60 mA (10 kHz) specified for mixed-frequency environments.
• Leakage Current — Rated leakage current of 6.6 µA for predictable DC performance after voltage application.
• Reliability & Endurance — Rated life of 2000 hours at 85°C; endurance limits are defined in the UVK series specifications.
• Operating Temperature Range — Specified for −40°C to +85°C to cover a wide range of ambient conditions.
• Compact Radial Package — Miniature φ5 × 11 mm can in a radial-lead format with 2.0 mm lead spacing (±0.5 mm tolerance) for easy through-hole placement.
• Packaging & Compliance — Available in bulk/no terminal forming or bag packing; RoHS compliant.
• Polarized — Designed as a polarized aluminum electrolytic capacitor for DC applications requiring polarity awareness.

Typical Applications

• General-purpose electronic assemblies — Fits applications that require a compact polarized electrolytic capacitor for filtering or energy storage in through‑hole designs.
• Space-constrained boards — Miniature φ5 × 11 mm footprint is intended for designs where board real estate is limited and a radial-lead component is preferred.
• Mixed-frequency circuitry — Specified low- and high-frequency ripple current ratings allow use in circuits experiencing both 120 Hz and higher-frequency ripple components.

Unique Advantages

• Compact footprint: φ5 × 11 mm size (L: 1.1 cm × D: 0.5 cm) helps reduce PCB area while retaining required capacitance and voltage rating.
• 100 V rating in a miniature can: Enables higher-voltage designs without moving to a larger package.
• Measured low loss (tanδ = 0.08): Predictable AC behavior at 120 Hz contributes to stable filtering performance.
• Defined ripple handling: Separate low- and high-frequency ripple current specifications (30 mA at 120 Hz, 60 mA at 10 kHz) provide clear guidance for mixed-frequency applications.
• Durability at elevated temperature: 2000-hour endurance at 85°C supports longer-term operation in elevated ambient conditions.
• RoHS compliant and packaged for production: Available in bulk or bag packing to accommodate assembly and inventory preferences.
