UVK2C221MHD

The UVK2C221MHD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UVK series, designed as a miniature-sized, general-purpose polarized capacitor. With a 220 µF capacitance at a 160 V rating, it targets designs that require compact, high-voltage capacitance in through-hole form.

Key value comes from its compact φ16 × 30.5 mm can, specified ripple current performance at both low and high frequencies, a rated endurance of 2000 hours at 85°C, and RoHS compliance—attributes useful for reliable general-purpose power circuits.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance with a 160 V rated voltage and ±20% tolerance, providing a stable energy storage element for moderate-voltage designs.
• Radial Lead Package — Polarized radial-lead can (φ16 × 30.5 mm) with 7.5 mm lead spacing (±0.5 mm), suited for through-hole assembly and mechanical robustness in board-level power circuits.
• Ripple Current Performance — Low-frequency ripple current 580 mA at 120 Hz and high-frequency ripple current 928 mA at 10 kHz, enabling defined AC stress handling across a range of operating frequencies.
• Leakage Current — Specified leakage current of 1508 µA after rated voltage application, defined per the UVK series leakage criteria for higher-voltage parts.
• Endurance & Temperature — Rated for 2000 hours at 85°C and usable across a −40°C to +85°C operating range, supporting sustained operation in elevated-temperature environments.
• Miniature Series Characteristics — Part of the UVK “Miniature Sized” lineup, offering one rank smaller case sizes compared to the UVR series for tighter space constraints.
• Packaging & Status — Available in bulk (no terminal forming) or bag packing; product is in mass production and RoHS compliant.

Typical Applications

• General-Purpose Power Filtering — Use the 220 µF/160 V rating for bulk smoothing and energy storage in general-purpose power supply circuits where compact radial components are preferred.
• Power Conversion — Suitable where defined ripple current handling at both low (120 Hz) and high (10 kHz) frequencies is required to manage AC stress on the capacitor.
• Board-Level Through-Hole Designs — Radial-lead form and compact φ16 × 30.5 mm can are useful for through-hole assemblies that require a polarized electrolytic capacitor with a small footprint.

Unique Advantages

• Compact high-voltage option: 160 V rating in a miniature φ16 can provides elevated voltage capability without a larger package footprint.
• Dual-frequency ripple specs: Defined ripple current values at 120 Hz and 10 kHz give clear guidance for thermal and AC stress planning in both line-frequency and switching applications.
• Long endurance at elevated temperature: 2000 hours at 85°C supports designs requiring predictable life performance under sustained thermal load.
• Precise mechanical footprint: 7.5 mm lead spacing with ±0.5 mm tolerance simplifies PCB layout and mechanical placement for through-hole manufacturing.
• Regulatory hygiene: RoHS compliance and mass-production availability ensure easier sourcing and environmental alignment for volume designs.
