UPJ1A222MHD6

The UPJ1A222MHD6 is a miniature radial-lead aluminum electrolytic capacitor from Nichicon’s UPJ series, providing 2200 µF capacitance at a 10 V rating in a compact φ18 × 15 mm can. It is a polarized, low-impedance capacitor designed for high-reliability power filtering in switching power supply and general-purpose power applications.

Key attributes include high ripple-current capability (1.296 A at 120 Hz and 1.44 A at high frequency), long endurance under load (5,000 hours at 105°C), and a wide operating temperature range of -55°C to +105°C—making it suitable for demanding power-rail smoothing and decoupling roles.

Key Features

• Capacitance & Voltage: 2200 µF (2.2 mF) rated at 10 V for bulk energy storage and power-rail smoothing.
• Low Impedance, Switching Supply Optimized: Designed for low impedance behavior that complements switching power supply topologies.
• High Ripple Current Handling: Rated ripple current of 1.296 A at 120 Hz (low frequency) and 1.44 A at high frequency supports substantial AC stress on power rails.
• Extended Endurance: 5,000 hours rated life at 105°C under DC bias plus rated ripple current for long-term reliability in hot environments.
• Loss Characteristics: Measured tanδ (DF) of 0.21 at 20°C, 120 Hz, 10 V, providing a quantified dissipation factor for thermal and ESR considerations.
• Compact Radial Package: φ18 × 15 mm can with 7.5 mm lead spacing (±0.5 mm) and radial lead mounting for through-hole PCB designs.
• Leakage Current: Specified leakage current of 660 µA for predictable standby and fault current budgeting.
• Compliance: RoHS compliant.
• Packaging & Availability: Available in bulk (no terminal forming) or bag packing; product is in mass production.

Typical Applications

• Switching Power Supplies: Bulk smoothing and output filtering where low impedance and high ripple handling improve transient response and stability.
• DC–DC Converters: Input/output decoupling for point-of-load converters requiring compact high-capacitance components.
• Industrial Power Modules: Power-rail filtering in compact control and power assemblies operating across -55°C to +105°C.
• General-Purpose Electronics: Energy storage and noise suppression in consumer and professional equipment where through-hole mounting is required.

Unique Advantages

• High Capacitance in a Small Can: 2200 µF in a φ18 × 15 mm package enables designers to save board area while maintaining bulk storage.
• Designed for High-Ripple Environments: Specified ripple currents at both low and high frequency reduce thermal stress and extend service life in switching circuits.
• Proven High-Temperature Endurance: 5,000 hours at 105°C under rated conditions provides predictable longevity for hot-case applications.
• Measurable Dissipation Factor: tanδ of 0.21 at defined conditions helps with ESR-related thermal design and stability calculations.
• Through-Hole Radial Format: Radial leads and 7.5 mm lead spacing simplify insertion and soldering for hand-assembly and wave-solder processes.
• Regulatory Compliance: RoHS compliance supports use in environments requiring restricted-substance conformity.
