UVK2E221MHD

The UVK2E221MHD is a radial-lead aluminum electrolytic capacitor offering 220 µF capacitance at a 250 V rating in a compact φ18 × 35.5 mm can. It is part of Nichicon’s UVK series, a miniature-sized family designed for general-purpose electronic applications.

Engineered for dependable DC energy storage and filtering in general-purpose designs, the UVK2E221MHD combines a broad operating temperature range with defined endurance and ripple performance for reliable duty in standard electronic assemblies.

Key Features

• Capacitance & Voltage — 220 µF capacitance with a 250 V rated voltage and ±20% tolerance, providing stable bulk capacitance for medium-voltage circuits.
• Radial-Lead, Through-Hole Mounting — Radial lead construction with 7.5 mm lead spacing (±0.5 mm) for straightforward PCB insertion and soldering in through-hole assemblies.
• Compact Miniature Size — φ18 × 35.5 mm can dimensions deliver a smaller footprint while maintaining rated capacitance, reflecting the UVK series’ one-rank-smaller case sizing.
• Temperature Capability — Rated for operation from –40 °C to +85 °C, suitable for a wide range of standard environmental conditions.
• Endurance — 2000 hours at 85 °C with performance limits defined for capacitance change, tan δ, and leakage current after the endurance test.
• Ripple Performance — Low-frequency ripple current of 680 mA at 120 Hz and high-frequency ripple current of 1.088 A at 10 kHz for filtering and decoupling across common ripple bands.
• Leakage Current — Specified leakage current up to 2300 µA, per the product’s rated conditions.
• RoHS Compliant — Conforms to RoHS directive requirements as noted for the UVK series.

Typical Applications

• General-purpose electronics — Bulk capacitance and voltage capability for a variety of standard electronic designs classified as general-purpose applications.
• Through-hole power assemblies — Radial-lead form factor and 7.5 mm lead spacing for integration into through-hole power supplies and discrete circuitry.
• Filtering and decoupling — Suitable where 220 µF at 250 V is required to smooth or decouple DC rails within the stated temperature and endurance limits.

Unique Advantages

• Miniature case size: One-rank-smaller case sizing gives designers more PCB layout options while retaining rated capacitance.
• Defined endurance data: 2000-hour life at 85 °C lets designers plan for long-term performance within the specified limits for capacitance, tan δ, and leakage.
• Clear ripple specifications: Separate low- and high-frequency ripple current ratings (680 mA @120 Hz and 1.088 A @10 kHz) support predictable thermal and electrical design margins.
• Wide temperature operation: –40 °C to +85 °C rating supports deployment across typical ambient conditions without additional qualification claims.
• Radial-lead convenience: Through-hole lead format with standardized spacing simplifies assembly and replacement in serviceable designs.
• Regulatory compliance: RoHS compliance provides environmental conformity for products sold in applicable markets.
