• Low Impedance: Rated impedance of 70 mΩ, supporting effective high-frequency filtering and fast transient response in power circuits.
• High Ripple Capability: Low-frequency ripple current of 1.543 A (120 Hz) and high-frequency ripple current of 1.815 A (10 kHz), enabling reliable smoothing under varying switching conditions.
• Long Endurance: Life rating of 5000 hours at 105°C, providing extended operational reliability for high-temperature applications.
• Wide Temperature Range: Rated for operation from -55°C to +105°C to accommodate harsh thermal environments.
• Radial Lead Package: Radial-lead, can-style package (φ10 × 30.5 mm) with 5.0 mm lead spacing (±0.5 mm), available in bulk or bag packing for flexible assembly handling.
• Electrical Leakage & Dissipation: Specified leakage current of 660 µA and a tangent of loss angle (tan δ) of 0.21 under measurement conditions (20°C, 120 Hz, 10 V), useful for predicting loss and standby drain in designs.
• Polarized Design: Polarized construction for DC power applications where correct polarity is maintained.
• AEC-Q200 Rating: AEC-Q200 listed in specifications for customers requiring AEC qualification.

Typical Applications

• Switching Power Supplies: Bulk and output smoothing where the UPW1A222MPD6’s low impedance and high ripple current capability improve voltage stability across DC–DC converters.
• Automotive Electronic Modules: Power filtering and decoupling in automotive control units and modules, leveraging the part’s AEC-Q200 rating and extended temperature range.
• Embedded and Industrial Power Systems: Local energy storage and transient suppression in embedded controllers and industrial power electronics that require long endurance at elevated temperatures.

Unique Advantages

• Compact, High-Capacity Packaging: 2200 µF in a φ10 × 30.5 mm can reduces board area for bulk capacitance without sacrificing capacitance value.
• Predictable Thermal Endurance: 5000-hour rating at 105°C gives designers a clear metric for lifetime planning in thermally demanding systems.
• Effective Ripple Handling: Specified ripple current ratings at both low and high frequencies support reliable operation with switching converters across a wide frequency range.
• Low Loss Behavior: Measured tan δ and defined leakage current allow accurate estimation of dissipation and standby power loss for power-budget sensitive designs.
• Automotive-Grade Qualification: Inclusion of AEC-Q200 in the specifications supports selection for automotive electronics where that qualification is required.
• Through-Hole Robustness: Radial lead mounting and can package simplify handling and provide mechanical durability for modules subject to vibration or thermal cycling.
