UPA1V222MHD

The UPA1V222MHD is a radial-lead aluminum electrolytic capacitor in Nichicon’s UPA series, designed for compact power applications. It delivers 2200 µF at 35 V in a miniature φ16 × 25 mm can with low impedance and high ripple-current capability.

Engineered for general-purpose power filtering and switching power supply use, this RoHS-compliant unit combines high ripple handling, long endurance (5000 hours at 105°C), and a wide operating temperature range of −55°C to 105°C for reliable performance in demanding environments.

Key Features

• Capacitance & Rating: 2.2 mF (2200 µF) nominal capacitance with a rated voltage of 35 V and tolerance of −20% to +20%.
• Low Impedance: Rated impedance of 38 mΩ helps reduce voltage ripple and improves transient response in power rails.
• High Ripple Current: Supports 2.346 A at 120 Hz (low frequency) and 2.76 A at 10 kHz (high frequency), suitable for smoothing and decoupling in switching supplies.
• Thermal & Endurance: Operating temperature −55°C to 105°C and endurance of 5000 hours at 105°C under rated conditions for long-term reliability.
• Electrical Losses: Dissipation factor (tan δ) of 0.14 measured at 20°C, 120 Hz; leakage current noted at 2310 µA as provided.
• Radial Lead Package: Compact φ16 × 25 mm can with radial leads, lead spacing 7.5 mm (±0.5 mm) for through-hole board mounting and straightforward assembly.
• Polarized Construction: Polarized aluminum electrolytic type intended for DC power filtering and smoothing applications.
• Packaging & Availability: Supplied in bulk or bag packing (no terminal forming); status: mass production. RoHS-compliant.

Typical Applications

• Switching Power Supplies — Low impedance and high ripple-current capacity make this capacitor suitable for output smoothing and bulk decoupling in DC–DC converters and SMPS designs.
• Power Filtering & Smoothing — Use for bulk energy storage and ripple reduction on power rails where compact size and reliable performance are required.
• General-Purpose Electronics — Applicable to consumer and industrial devices that require robust electrolytic capacitance with a wide temperature range and extended lifetime.

Unique Advantages

• Compact, High-Capacity Form Factor: 2200 µF in a φ16 × 25 mm can provides significant bulk capacitance in a small footprint for space-constrained PCBs.
• Improved Power Handling: High rated ripple currents (2.346 A at 120 Hz, 2.76 A at 10 kHz) reduce heating and extend service life in pulse-loaded power circuits.
• Low-Impedance Performance: 38 mΩ impedance reduces voltage ripple and improves regulation and transient response on supply lines.
• Long Endurance at Elevated Temperature: 5000 hours at 105°C under rated conditions supports durability in sustained high-temperature applications.
• Wide Operating Range: −55°C to 105°C allows deployment across diverse environments without sacrificing capacitance or reliability.
• Production-Ready Supply: Mass-production status and standard bulk/bag packaging simplify procurement and assembly planning.
