UPW1A222MHD

The UPW1A222MHD is a miniature, radial-lead aluminum electrolytic capacitor in Nichicon’s UPW series designed for high-reliability applications. It is a polarized, low-impedance component specified for demanding environments with a rated voltage of 10 V and a nominal capacitance of 2200 µF (2.2 mF).

Targeted use cases include power-supply filtering and decoupling in compact systems where high ripple handling, long life, and wide temperature range matter. Key value propositions are low impedance (76 mΩ), robust ripple-current capability, and a 7000-hour endurance at 105°C backed by AEC-Q200 qualification.

Key Features

• Capacitance & Voltage — 2200 µF nominal capacitance at a rated voltage of 10 V, with a tolerance of −20% to +20%.
• Low Impedance — Specified impedance of 76 mΩ supports effective smoothing and decoupling in high‑current circuits.
• High Ripple Current Handling — Low-frequency ripple current of 1.407 A (120 Hz) and high-frequency ripple current of 1.655 A (10 kHz) for improved thermal and electrical performance under AC loading.
• Leakage & Dissipation — Leakage current specified at 660 µA; tangent of loss angle (tanδ) measured at 0.21 (20°C, 120 Hz) for this capacitance value.
• Wide Temperature Range & Long Life — Operating range from −55°C to +105°C and rated endurance of 7000 hours at 105°C.
• Compact Radial Package — φ12.5 × 20L can (diameter 12.5 mm, length 20 mm) with 5.0 mm lead spacing (±0.5 mm); radial lead mounting for through-hole assemblies.
• AEC-Q200 Qualified — Designed and specified for applications requiring automotive-grade reliability (AEC-Q200 listed in product specifications).
• Packaging Options — Available in bulk (no terminal forming) or bag packing for flexible procurement and assembly handling.

Typical Applications

• Switching Power Supplies — Bulk and output filtering where low impedance and high ripple-current capability reduce voltage ripple and improve transient response.
• Automotive Electronics — Power smoothing and decoupling in vehicle electronic modules where AEC-Q200 qualification and extended temperature range are required.
• Industrial Power Modules — DC bus support and energy buffering in compact converters and motor-drive controllers operating up to 105°C.

Unique Advantages

• Compact, High-Capacity Footprint — 2200 µF in a φ12.5 × 20 mm can saves PCB area while delivering substantial energy storage for miniaturized power assemblies.
• High Ripple Tolerance — Specified ripple currents at both low and high frequencies support stable performance across switching and audio-frequency environments.
• Long Endurance at Elevated Temperature — 7000 hours at 105°C provides predictable lifetime for designs intended for prolonged thermal stress.
• Automotive-Grade Reliability — AEC-Q200 listing enables confident use in automotive and similarly demanding markets that require documented component qualification.
• Through-Hole Robustness — Radial-lead construction and defined lead spacing offer strong mechanical retention and straightforward replacement or manual assembly.
