UVK2A221MHD

The UVK2A221MHD is a miniature aluminum electrolytic capacitor from Nichicon's UVK series, provided in a radial lead can package. It delivers 220 µF capacitance at a 100 V rating with a compact φ12.5 × 20 mm case and is designed for general-purpose electronic applications that require polarized bulk capacitance in a radial-leaded form.

This part combines high-voltage capability, defined endurance at elevated temperature, and measurable ripple handling to support designs where stable capacitance, controlled leakage, and long-term reliability are required.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance rated at 100 V, with a tolerance of -20% to +20%.
• Loss Angle (tan δ) — Specified tan δ of 0.08 (measured at 20°C, 120 Hz) for control over dissipation at the rated voltage.
• Ripple Current Handling — Low-frequency ripple current of 550 mA (120 Hz) and high-frequency ripple current of 825 mA (10 kHz) to support AC ripple demands within specified limits.
• Leakage Current — Specified leakage current of 660 µA for predictable standby and leakage behavior after voltage application.
• Endurance — Rated life of 2000 hours at 85°C with capacitance change within ±20% and leakage returning to initial specified limits after the endurance test.
• Operating Temperature Range — Specified to operate from -40°C to +85°C, accommodating a wide range of ambient conditions.
• Mechanical & Mounting — Radial lead configuration with 5 mm lead spacing (±0.5 mm tolerance) and a φ12.5 × 20 mm can size for through-hole assemblies.
• Compliance & Packaging — RoHS compliant; available in bulk (no terminal forming) or bag packing for production and prototyping workflows.

Typical Applications

• General Purpose — Intended for general-purpose electronic circuits requiring polarized bulk capacitance at 100 V and 220 µF in a radial-lead package.
• Through-Hole Assemblies — Radial lead form factor and 5 mm lead spacing for use where through-hole mounting is required.
• Elevated Temperature Environments — Applications that need defined endurance performance up to 85°C over extended periods (2000 hours rated life).

Unique Advantages

• High Voltage Capability: 100 V rating provides headroom for higher-voltage circuits compared with lower-voltage electrolytics.
• Compact Miniature Size: φ12.5 × 20 mm can size offers a smaller footprint relative to larger radial electrolytics while maintaining 220 µF capacitance.
• Defined Endurance: 2000 hours at 85°C gives a clear specification for lifetime planning and reliability assessment.
• Measured Ripple Performance: Specified ripple currents at 120 Hz and 10 kHz allow designers to account for both low- and high-frequency ripple loading.
• Predictable Leakage: Stated leakage current specification supports power budgeting and standby current calculations.
• RoHS Compliant & Packaged for Production: Environmentally compliant and available in bulk or bag packing to suit production or prototyping needs.
