UVK2W2R2MPD

The UVK2W2R2MPD is a radial-lead aluminum electrolytic capacitor in Nichicon’s UVK series, offering 2.2 µF capacitance at a 450 V rating in a compact φ8 × 11.5 mm can. It is a polarized, miniature-sized component designed for general-purpose electronic circuits that require high-voltage energy storage in a small footprint.

Key electrical characteristics include a capacitance tolerance of −20% to +20%, a measured tanδ of 0.25 at 20°C and 120 Hz, defined low- and high-frequency ripple currents, and a rated endurance of 2000 hours at 85°C. Packaging options include bulk (no terminal forming) and bag packing.

Key Features

• High voltage rating — Rated voltage of 450 V for applications that require elevated DC voltage handling.
• Compact radial package — φ8 × 11.5 mm can with 3.5 mm lead spacing (±0.5 mm) provides a small footprint for space-constrained designs.
• Capacitance and tolerance — 2.2 µF capacitance with −20% to +20% tolerance, suitable for general-purpose polarized capacitor requirements.
• Loss and measurement condition — tanδ (DF) of 0.25 measured at 20°C, 120 Hz, enabling predictable dissipation characteristics under the stated test conditions.
• Ripple current ratings — Low-frequency ripple current of 28 mA at 120 Hz and high-frequency ripple current of 44.8 mA at 10 kHz for decoupling and filtering duties within these limits.
• Leakage and endurance — Specified leakage current of 139 µA and endurance of 2000 hours at 85°C when the rated voltage is applied, supporting reliable lifetime performance under the defined conditions.
• Mounting and packaging — Radial lead mounting type with bulk (no terminal forming) or bag packing options to match assembly and procurement preferences.

Typical Applications

• High-voltage power filtering — Use in circuits that require 450 V-rated polarized capacitance for bulk filtering or energy storage in a compact radial package.
• General-purpose electronic modules — Suited for general-purpose designs needing a small, high-voltage electrolytic capacitor with defined ripple and leakage characteristics.
• Compact power supplies — Fits space-constrained power supply stages where a miniature high-voltage electrolytic capacitor is required.

Unique Advantages
