UVK2G220MHD

The UVK2G220MHD is a Nichicon UVK series aluminum electrolytic capacitor in a radial-lead can, designed for general-purpose high-voltage applications. It delivers 22 µF capacitance at a 400 V rated voltage in a compact, miniature-sized package suitable for through-hole mounting.

Engineered for reliability in elevated-temperature environments, the UVK2G220MHD offers defined endurance and ripple-handling characteristics for power-filtering and energy-storage roles in industrial and electronic designs.

Key Features

• Electrical Characteristics — 22 µF nominal capacitance with ±20% tolerance, polarized design and a 400 V rated voltage for high-voltage DC applications.
• Ripple Current Performance — Low-frequency ripple current of 200 mA (120 Hz) and high-frequency ripple current of 320 mA (10 kHz), enabling effective AC ripple suppression across common switching and mains frequencies.
• Leakage Current — Specified leakage current of 452 µA, measured at rated conditions and relevant to power-loss and standby-current budgets.
• Endurance and Temperature Range — Life rating of 2000 hours at 85°C with operating temperature range from –40°C to +85°C; endurance recovery criteria include capacitance within ±20% and leakage current meeting initial specified values after the test.
• Compact Radial Can Package — Miniature-sized φ12.5×25L radial can with 5 mm lead spacing (±0.5 mm), suited for through-hole PCB layouts where a small footprint is required.
• Compliance and Packaging — RoHS-compliant construction; available in bulk (no terminal forming) or bag packing for flexible procurement and assembly handling.

Typical Applications

• Power supply filtering — 400 V rating and defined ripple-current specs make this capacitor suitable for smoothing and filtering in high-voltage DC power supplies.
• DC-link and energy storage — Compact 22 µF capacitance and HF/LF ripple capability support energy buffering and decoupling in converters and inverters.
• Industrial control electronics — Polarized radial-lead format and robust temperature/endurance characteristics fit general-purpose control and instrumentation circuits.

Unique Advantages

• High-voltage capability: 400 V rated voltage enables use directly on high-voltage rails without series arrangements.
• Dual-frequency ripple handling: Specified LF and HF ripple currents (200 mA at 120 Hz, 320 mA at 10 kHz) accommodate both mains-frequency smoothing and switching-frequency noise suppression.
• Miniature footprint: φ12.5×25L radial can design provides a smaller case size within the UVK series for tight PCB layouts.
• Defined endurance at elevated temperature: 2000 hours at 85°C with specified recovery limits offers predictable aging behavior for project planning and reliability assessment.
• RoHS-compliant supply options: Environmentally compliant construction and flexible bulk or bag packing simplify procurement and assembly flow.
