UCA2G220MHD6

The UCA2G220MHD6 is a 22 µF, 400 V aluminum electrolytic capacitor from Nichicon's UCA series. It is a miniature, radial-leaded can designed for applications that require compact high-voltage decoupling with elevated ripple handling and extended operational life.

Targeted use cases include power supply filters and ballast circuits as well as other general-purpose high-voltage applications where long life and reliable ripple performance are important design criteria.

Key Features

• Capacitance & Rated Voltage — 22 µF at 400 V, suitable for high-voltage smoothing and energy storage in compact assemblies.
• High Ripple Current — Rated ripple current of 300 mA at 120 Hz and 600 mA at 100 kHz, enabling effective AC ripple handling across common supply frequencies.
• Long Operational Life — Designed for 12,000 hours at +105°C under rated conditions, supporting extended deployment in demanding thermal environments.
• Compact Radial Can Package — Radial lead mounting with a lead spacing of 7.5 mm and physical size L: 2 × D: 1.6 cm for space-constrained PCB layouts.
• Operating Temperature Range — Specified for –25°C to +105°C to cover a broad set of industrial and commercial temperature environments.
• Leakage Current Specification — Leakage current after 1 minute at 20°C is specified as not more than 0.04CV + 100 (µA), providing a measurable baseline for design verification.
• Capacitance Tolerance & Polarization — ±20% tolerance (at 120 Hz, 20°C) and polarized construction; suitable for designs accommodating electrolytic polarity.
• RoHS Compliant — Meets RoHS requirements as stated in the product documentation.

Typical Applications

• Power Supplies — Bulk filtering and ripple reduction on high-voltage rails where elevated ripple current capability and long life are required.
• Ballast Circuits — AC ripple management and smoothing in lighting ballast designs.
• General-Purpose High-Voltage Electronics — Energy storage and decoupling in compact assemblies that need a 400 V rated electrolytic solution.

Unique Advantages

• High ripple tolerance: Enables reliable operation under continuous AC ripple exposure thanks to specified ripple currents at multiple frequencies.
• Extended life at elevated temperature: 12,000-hour rating at +105°C provides predictable longevity for designs with sustained thermal stress.
• Compact footprint: Small radial-can dimensions (L: 2 × D: 1.6 cm) and 7.5 mm lead spacing help conserve PCB area in power-dense layouts.
• Measurable leakage baseline: The defined leakage current formula (0.04CV + 100 µA) supports margin calculations and quality checks during design and incoming inspection.
• Broad operating range: –25°C to +105°C rating supports a variety of industrial and commercial environments.
• Series pedigree: Part of Nichicon’s UCA family, which emphasizes high ripple capability and long life for power applications.
