UVK2E220MPD

The UVK2E220MPD is a radial-lead aluminum electrolytic capacitor in Nichicon’s UVK series, offering 22 µF capacitance at a 250 V rated voltage. The part is designed for general-purpose electronic applications that require a compact, polarized electrolytic solution with defined ripple and leakage performance.

This miniature-sized capacitor (φ10 × 20 mm can) combines a -40 °C to +85 °C operating range with a 2000-hour endurance at 85 °C, making it suitable for compact high-voltage circuits where board-space efficiency and predictable long-term behavior are important.

Key Features

• Electrical Rating — 22 µF capacitance with ±20% tolerance and a 250 V rated voltage for higher-voltage general-purpose circuits.
• Ripple and Leakage Performance — Low-frequency ripple current 150 mA (120 Hz), high-frequency ripple current 240 mA (10 kHz), and specified leakage current of 320 µA for controlled loss and self-discharge behavior.
• Reliability & Endurance — Rated for 2000 hours at 85 °C with defined post-test limits (capacitance within ±20%, tan δ within 200% of initial, leakage ≤ initial spec), supporting predictable lifetime performance.
• Temperature Range — Operates from -40 °C to +85 °C to cover a wide range of ambient conditions.
• Compact Radial Package — φ10 × 20 mm can with 5 mm lead spacing (±0.5 mm) and radial lead mounting for through-hole assemblies and retrofit/repair applications.
• Packaging & Supply — Available in bulk (no terminal forming) or bag packing; product is in mass production and RoHS compliant.
• Series Characteristics — Part of the UVK series, noted for miniature-sized cans and one-rank-smaller case sizes compared to UVR (as described in the series datasheet).

Typical Applications

• General Purpose Electronics — Suited to circuits that require a 22 µF, 250 V polarized capacitor in a compact radial-lead package.
• Compact High-Voltage Designs — The φ10 × 20 mm can and 5 mm lead spacing enable use where board space is limited but a 250 V rating is needed.
• Higher-Temperature Environments — Use in assemblies that operate up to +85 °C and require a component with a specified 2000-hour endurance at that temperature.

Unique Advantages

• Voltage headroom in a small footprint: 250 V rating in a φ10 × 20 mm radial can supports higher-voltage designs without a larger package.
• Balanced ripple handling: Defined ripple current specs at both 120 Hz (150 mA) and 10 kHz (240 mA) help designers assess AC load capability across frequencies.
• Predictable leakage: Specified leakage current (320 µA) provides a clear baseline for self-discharge and bias considerations in circuit design.
• Durability at elevated temperature: 2000-hour endurance at 85 °C with post-test limits ensures known long-term behavior for thermal stress conditions.
• RoHS-compliant supply: Environmentally compliant manufacturing and availability in bulk or bag packing support production and prototyping workflows.

Why Choose UVK2E220MPD?

UVK2E220MPD is positioned for designers who need a compact, polarized aluminum electrolytic capacitor with a 250 V rating and defined endurance at elevated temperature. Its combination of miniature can size, clear ripple and leakage specifications, and 2000-hour life at 85 °C provides predictable electrical and thermal behavior for general-purpose circuits.

This part is suitable for engineers and procurement teams seeking a RoHS-compliant, mass-production component for through-hole assemblies where board-space efficiency and verified long-term performance matter. The UVK series’ miniature sizing offers an option when a smaller can is required compared to larger series alternatives.
