UPW1A103MHD

The UPW1A103MHD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UPW series, engineered for miniature, low-impedance power applications. It offers 10,000 µF capacitance at a 10 V rating in a compact φ18 × 35.5 mm can with 7.5 mm lead spacing.

Designed for switching power supplies and demanding electronic modules, this part combines high ripple-current capability, long endurance at elevated temperature, and AEC-Q200 qualification for use in automotive and industrial environments.

Key Features

• High Capacitance — 10,000 µF (10 mF) bulk energy storage for smoothing, hold-up and decoupling in compact power stages.
• 10 V Rated Voltage — Suited for low-voltage power rails and DC bus applications requiring substantial capacitance at 10 V.
• Low Impedance — 30 mΩ impedance for reduced ripple voltage and improved transient performance in switching circuits.
• High Ripple Current — Handles 3.128 A at 120 Hz (low frequency) and 3.68 A at 10 kHz (high frequency), enabling reliable operation under AC ripple stress.
• Loss Characteristics — Measured tangent of loss angle (tan δ) of 0.37 at 20°C, 120 Hz and 10 V for planning AC loss and thermal considerations.
• Wide Temperature Range — Operates from −55°C to 105°C, supporting designs exposed to broad thermal environments.
• Long Endurance — 8,000 hours rated life at 105°C for extended reliability in continuous high-temperature operation.
• Compact Radial Can — φ18 × 35.5 mm package with 7.5 mm lead spacing and bulk/bag packing; radial-lead format for through-hole assemblies.
• Leakage Current — Specified leakage of 3,000 µA for margining in power-budget and standby calculations.
• AEC-Q200 Rated — Qualified to AEC-Q200, supporting use in automotive electronic modules where that qualification is required.

Typical Applications

• Switching Power Supplies — Bulk smoothing and output decoupling to reduce ripple and improve regulation in compact converters.
• Automotive Electronic Modules — Energy storage and ripple handling in vehicle control units and power electronics that require AEC-Q200-qualified passives.
• Compact Power Assemblies — High-capacitance, low-impedance solution for DC bus support and power-rail stabilization in space-constrained designs.

Unique Advantages

• High Energy Density in a Small Footprint: 10,000 µF in a φ18 × 35.5 mm can provides significant capacitance where board area is limited.
• Designed for High Ripple Environments: Specified ripple currents at both 120 Hz and 10 kHz enable reliable performance across switching and mains-frequency stress.
• Thermal Endurance: 8,000 hours at 105°C supports long service life in elevated-temperature installations.
• Low ESR/Impedance: 30 mΩ impedance minimizes power loss and voltage ripple, improving converter efficiency and transient response.
• Automotive-Grade Qualification: AEC-Q200 rating aligns the part with automotive module requirements for passive components.
• Through-Hole Robustness: Radial-lead can package with 7.5 mm lead spacing simplifies mechanical mounting and board-level reliability.
