UVK2W220MHD

The UVK2W220MHD is a Nichicon UVK-series miniature aluminum electrolytic capacitor in a radial-lead, standard type construction. It delivers 22 µF capacitance at a 450 V rating in a compact φ12.5 × 25 mm can with 5 mm lead spacing.

Designed for general-purpose electronic designs, this component combines high-voltage capability with a small footprint, measurable ripple handling and defined endurance for reliable performance in equipment operating up to 85°C.

Key Features

• Electrical Performance — Rated capacitance 22 µF at 450 V with ±20% tolerance, tanδ (DF) 0.25 measured at 20°C, 120 Hz, and specified leakage current of 496 µA.
• Ripple Current Handling — Low-frequency ripple current 140 mA (120 Hz) and high-frequency ripple current 224 mA (10 kHz) for applications with AC ripple or switching noise.
• Reliability & Endurance — Endurance specified to 2000 hours at 85°C with capacitance change within ±20% and leakage current within initial specified limits after test.
• Compact Mechanical Package — Miniature radial can with dimensions φ12.5 × 25 mm, lead spacing 5.0 mm (tolerance ±0.5 mm), and radial lead mounting for through-hole boards.
• Series Attributes — Part of the UVK miniature series noted for one-rank-smaller case sizes relative to the UVR series, helping designers reduce board area.
• Compliance & Packing — RoHS compliant; available in bulk (no terminal forming) and bag packing options.

Typical Applications

• General Purpose Electronics — Intended for general-purpose use where a 22 µF, 450 V radial aluminum electrolytic capacitor is required.
• Compact High‑Voltage Designs — Suitable for designs that need a high-voltage capacitor in a miniature φ12.5 × 25 mm can with 5 mm lead spacing.
• Endurance‑Sensitive Assemblies — Appropriate for equipment requiring documented 2000 h endurance at 85°C and predictable post-test characteristics.

Unique Advantages

• High‑Voltage Capability: 450 V rating provides voltage margin for high-voltage circuits requiring compact capacitance.
• Small Footprint: Miniature φ12.5 × 25 mm can and one-rank-smaller case sizing from the UVK series reduce PCB area compared with larger series.
• Defined Endurance: 2000 hours at 85°C gives a clear specification for lifecycle planning and thermal stress considerations.
• Measured Loss and Leakage: Specified tanδ (0.25 at 20°C, 120 Hz) and leakage current (496 µA) enable predictable AC loss and standby current budgeting.
• Practical Ripple Handling: Explicit low- and high-frequency ripple current ratings (140 mA @ 120 Hz, 224 mA @ 10 kHz) support selection for ripple-sensitive circuits.
• RoHS Compliance and Packaging Options: RoHS compliant material set with bulk and bag packing choices for flexible handling and assembly workflows.
