UPW0J123MHD

The UPW0J123MHD is a radial-lead aluminum electrolytic capacitor offering 12,000 µF capacitance at a 6.3 V rating in a compact φ18 × 30.5 mm can. It is engineered for low impedance and high reliability in power-electronics environments, including switching power supplies and demanding automotive electronics.

Key electrical characteristics include a low impedance of 32 mOhm, high ripple-current capability (3.09 A at 120 Hz / 3.635 A at 10 kHz), and long endurance (8,000 hours at 105°C). The part is in mass production and available in bulk/bag packaging.

Key Features

• High Capacitance, Low Voltage — 12,000 µF at 6.3 V provides bulk energy storage and smoothing in compact board space (φ18 × 30.5 mm).
• Low Impedance — Rated impedance of 32 mOhm supports reduced voltage ripple and improved transient response in power rails.
• High Ripple Current Handling — Low-frequency ripple current of 3.08975 A at 120 Hz and high-frequency ripple current of 3.635 A at 10 kHz for demanding switching environments.
• Long Endurance — Designed for 8,000 hours of operation at 105°C, enabling extended service life under elevated-temperature stress.
• Wide Temperature Range — Operating range from −55°C to 105°C to accommodate harsh ambient conditions.
• Automotive-Grade Screening — AEC-Q200 rating for designs requiring automotive-level component qualification.
• Radial Lead Package — φ18 can with 7.5 mm lead spacing (±0.5 mm) and bulk/bag packing for straightforward through-hole assembly.
• Measured Dissipation Factor — tan δ = 0.44 measured at 20°C, 120 Hz (6.3 V), shown for design verification and loss budgeting.

Typical Applications

• Switching Power Supplies — Bulk smoothing and output filtering where low impedance and high ripple current capability reduce output ripple and improve regulator stability.
• Automotive Electronics — Suited for automotive systems that require AEC-Q200 screening and operation across −55°C to 105°C with long-endurance performance.
• DC‑DC Converters and Power Modules — Energy storage and decoupling in power conversion stages that face high ripple and transient loads.

Unique Advantages

• High Capacitance in a Small Footprint: 12,000 µF in a φ18 × 30.5 mm can minimizes board area while supplying substantial bulk energy.
• Engineered for Ripple Performance: Specified ripple currents at 120 Hz and 10 kHz support both low- and high-frequency filtering needs in switching applications.
• Long Life at Elevated Temperature: 8,000 hours at 105°C provides predictable end-of-life planning for thermal-stressed designs.
• Automotive Screening: AEC-Q200 rating enables use where automotive-grade qualification is required.
• Through-Hole Simplicity: Radial lead form factor and 7.5 mm lead spacing facilitate reliable, serviceable through-hole assembly and replacement.
• Measured Loss Data: Specified tan δ at measurement conditions (20°C, 120 Hz, 6.3 V) supports thermal and loss analysis during design.
