UVK2V2R2MED

The UVK2V2R2MED is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon’s UVK series. It is a polarized, standard-type electrolytic capacitor rated at 2.2 µF and 350 V, designed for general-purpose electronic applications where compact size and high-voltage capability are required.

Key value propositions include a compact φ6.3 × 11 mm can, low leakage current, defined ripple current performance at both low and high frequencies, and proven endurance across a wide operating temperature range.

Key Features

• Electrical Rating — 2.2 µF capacitance with a 350 V rated voltage and ±20% tolerance, providing stable DC energy storage in high-voltage circuits.
• Loss Characteristics — Specified tangent of loss angle (tan δ) of 0.25 measured at 20°C, 120 Hz, enabling predictable dissipation characteristics at the rated condition.
• Ripple Current Performance — Low-frequency ripple current of 30 mA at 120 Hz and high-frequency ripple current of 48 mA at 10 kHz for defined AC stress handling in filtering and decoupling roles.
• Leakage Current — Leakage current specified at 117 µA, suitable for applications requiring low standby leakage.
• Endurance and Temperature Range — Rated for 2000 hours at 85°C with an operating temperature range of −40°C to +85°C, supporting long-term use in elevated-temperature environments.
• Mechanical and Packaging — Miniature radial can package (φ6.3 × 11 mm) with 2.5 mm lead spacing; available in bulk (no terminal forming) and bag packing for flexible assembly handling.
• Environmental Compliance — RoHS-compliant construction, aligning with common environmental requirements.

Typical Applications

• General-purpose power filtering — Provides DC smoothing and bulk capacitance in compact power supplies and voltage rails where a 350 V rating is required.
• High-voltage decoupling — Used for decoupling and noise suppression in circuits that operate at elevated DC voltages and need a small footprint.
• Compact electronic modules — Miniature φ6.3 × 11 mm can and radial-lead format suit space-constrained assemblies and through-hole layouts.

Unique Advantages

• 350 V rating in a miniature package — Enables high-voltage designs to use a compact electrolytic capacitor without increasing board area.
• Defined AC performance — Specified ripple current values at 120 Hz and 10 kHz provide clear parameters for thermal and lifetime calculations under AC stress.
• Low leakage for predictable bias behavior — 117 µA leakage current helps maintain predictable voltage hold and minimizes idle power draw.
• Proven endurance at elevated temperature — 2000 hours at 85°C gives designers a measurable baseline for long-term reliability planning.
• Small can and standard radial leads — φ6.3 × 11 mm size with 2.5 mm lead spacing simplifies integration into existing through-hole assemblies and tight layouts.
• RoHS compliant — Meets common environmental restrictions for electronic assemblies.
