UPA1A222MHD3

The UPA1A222MHD3 is a radial‑lead aluminum electrolytic capacitor from Nichicon's UPA series. It is a polarized, miniature can‑style capacitor designed for general‑purpose use and switching power supply applications where low impedance, high ripple handling and compact size are required.

Key electrical characteristics include 2.2 mF capacitance at 10 V, a measured impedance of 58 mΩ, and rated ripple current specifications at both low and high frequencies. The part is RoHS compliant and built for continuous operation across a wide temperature range.

Key Features

• Capacitance & Voltage — 2.2 mF (2200 μF) rated at 10 V for bulk energy storage and smoothing in low‑voltage power rails.
• Low Impedance — Specified impedance of 58 mΩ to reduce AC voltage drop and improve ripple suppression in switching supplies.
• High Ripple Current — Rated ripple current of 1.607 A at 120 Hz and 1.89 A at 10 kHz to support high AC stress environments.
• Temperature & Lifetime — Operating range from −55 °C to +105 °C with a life rating of 5000 hours at 105 °C for extended reliability under elevated temperatures.
• Package & Mounting — Radial lead, can package with 5 mm lead spacing; compact footprint with dimensions L: 2 cm × D: 1.25 cm and maximum seated height of 2 cm.
• Tolerance & Polarity — Capacitance tolerance −20% to 20%; polarized construction for DC filter and smoothing applications.
• Environmental Compliance — Compliant to RoHS directives (2011/65/EU, (EU)2015/863).

Typical Applications

• Switching Power Supplies — Bulk smoothing and ripple suppression where low impedance and high ripple current are required.
• General Purpose Power Filtering — DC rail decoupling and energy storage in compact assemblies that demand a small case size.
• Power Regulation Modules — Input/output filtering for regulators and converters operating up to 10 V and across a wide temperature range.

Unique Advantages

• Reduced AC Losses: Low impedance (58 mΩ) directly lowers ripple voltage and improves regulator stability under dynamic loads.
• Compact Footprint: Small radial can (L: 2 cm × D: 1.25 cm) saves PCB space compared with larger electrolytic options.
• High Ripple Capability: Specified ripple currents of 1.607 A (120 Hz) and 1.89 A (10 kHz) support high‑stress switching environments.
• Wide Temperature Range and Proven Lifetime: −55 °C to +105 °C rating and 5000 h life at 105 °C provide predictable durability in demanding thermal conditions.
• Regulatory Compliance: RoHS compliance simplifies integration into products targeting markets with restricted substances requirements.
