UPW1J222MHD

The UPW1J222MHD is a miniature, high-reliability aluminum electrolytic capacitor in Nichicon’s UPW series. It is a radial lead, polarized device specified at 2.2 mF (2200 µF) and 63 V, designed for demanding power-electronic environments.

Engineered for low impedance and elevated ripple handling, this part is targeted at switching power supplies and automotive electronics where long endurance and stable performance across –55 °C to 105 °C are required.

Key Features

• Capacitance & Voltage — 2.2 mF (2200 µF) nominal capacitance with a rated voltage of 63 V and tolerance of −20% to +20% for bulk energy storage and decoupling.
• Low Impedance — Specified impedance of 56 mΩ to minimize voltage ripple and improve transient response in power rails.
• High Ripple Current Capability — Rated ripple current of 2.72 A at 120 Hz (low frequency) and 3.2 A at 10 kHz (high frequency) for robust AC stress performance.
• Loss Characteristic (tan δ) — tanδ of 0.11 measured at 20 °C, 120 Hz, providing a quantified dissipation factor for thermal and loss budgeting.
• Long Endurance — Life rating of 8000 hours at 105 °C for sustained high-temperature operation.
• Temperature Range — Rated operation from −55 °C to +105 °C to support harsh-environment applications.
• Packaging & Form Factor — Radial lead can (φ18 × 40 mm length) with 7.5 mm lead spacing (±0.5 mm) and bulk/bag packing options for straightforward through-hole assembly.
• Qualification — AEC-Q200 listed rating and explicit application for automotive use.

Typical Applications

• Switching Power Supplies — Low-impedance, high ripple-current capability supports input/output smoothing and bulk energy storage in switching regulators.
• Automotive Electronics — AEC-Q200 rating and 8000 h endurance at 105 °C make this capacitor suitable for automotive electronic modules requiring long-term thermal reliability.
• High-Reliability Power Filtering — Miniature size with quantified impedance and dissipation factor for compact power designs demanding stable filtering performance across temperature.

Unique Advantages

• Quantified Thermal Endurance: 8000-hour life at 105 °C gives designers a clear durability metric for high-temperature systems.
• High AC Stress Capability: Measured ripple currents of 2.72 A (120 Hz) and 3.2 A (10 kHz) reduce the need for overspecifying parallel capacitors in many power designs.
• Low ESR/Impedance: 56 mΩ impedance helps minimize ripple voltage and improves converter stability and transient response.
• AEC-Q200 Rated: Explicit AEC-Q200 rating supports use in automotive-qualified designs and aligns with automotive deployment requirements.
• Compact Radial Package: φ18 × 40 mm can with 7.5 mm lead spacing provides a space-efficient, through-hole solution for power boards and modules.
