UPA1A222MPD

The UPA1A222MPD is a miniature, high-reliability aluminum electrolytic capacitor in a radial-lead can designed for demanding power applications. It delivers 2200 µF capacitance at a 10 V rating with a compact φ10 × 25 mm case and 5 mm lead spacing.

Optimized for switching power supplies and general-purpose power filtering, this part combines low impedance, high ripple-current capability and long endurance (4000 hours at 105°C) to support stable power delivery in compact electronic systems.

Key Features

• Capacitance & Voltage — 2200 µF nominal capacitance with ±20% tolerance at 120 Hz, rated for 10 V operation.
• Low Impedance — Specified impedance of 66 mΩ, supporting effective smoothing and decoupling in power rails.
• Controlled Dissipation Factor — tanδ measured at 0.21 (20°C, 120 Hz, 10 V) for predictable AC loss characteristics.
• High Ripple Current Capability — Low-frequency ripple current 1.428 A at 120 Hz and high-frequency ripple current 1.68 A at 10 kHz to handle switching-waveform stress.
• Leakage Current — Specified leakage current of 660 µA for predictable standby and bias conditions.
• High Endurance — Rated life of 4000 hours at 105°C, suitable for long-term operation in elevated-temperature environments.
• Temperature Range — Operates from −55°C to +105°C to accommodate a wide range of ambient conditions.
• Radial Lead Package — φ10 × 25 mm can, 5 mm lead spacing, available in bulk (no terminal forming) or bag packing; polarized radial-lead mounting for through-hole assemblies.
• RoHS Compliance — Manufactured to meet RoHS directive requirements.

Typical Applications

• Switching Power Supplies — Bulk smoothing and output filtering where low impedance and high ripple capability reduce output ripple and improve regulation.
• Power Filtering & Decoupling — Local energy storage and transient suppression on DC rails in compact power modules and point-of-load circuits.
• Industrial Power Electronics — Energy buffering and ripple management in control and drive systems that require elevated temperature endurance.
• General-Purpose Electronics — Bulk capacitance for consumer and professional devices needing stable DC supply filtering with compact footprint.

Unique Advantages

• Compact, high-capacitance package: 2200 µF in a φ10 × 25 mm can conserves PCB area while providing significant bulk energy storage.
• Designed for switching environments: Low impedance (66 mΩ) and specified ripple currents at both 120 Hz and 10 kHz support switching-waveform robustness.
• Long-term thermal endurance: 4000 hours at 105°C enables reliable operation in elevated-temperature installations.
• Predictable electrical behavior: Specified tanδ (0.21) and measured leakage current (660 µA) simplify design margining and thermal budgeting.
• Through-hole ease-of-use: Radial lead form with 5 mm lead spacing facilitates secure mechanical mounting and straightforward assembly in legacy and industrial PCBs.
• Regulatory compliance: RoHS-compliant construction supports modern environmental requirements.
