UPW1C103MHD

The UPW1C103MHD is a radial-lead aluminum electrolytic capacitor in Nichicon’s UPW series designed for miniature, low-impedance, high-reliability power applications. It delivers 10,000 µF at a 16 V rating in a φ18 × 40 mm can with 7.5 mm lead spacing, and is supplied in bulk or bag packing for production use.

Engineered for demanding thermal and ripple conditions, the part targets switching power supplies and automotive electronics where high capacitance, long endurance, and robust ripple handling are required.

Key Features

• High Capacitance: 10,000 µF nominal capacitance with ±20% tolerance, providing substantial bulk energy storage and smoothing for power rails.
• Rated Voltage: 16 V DC rating suitable for low-voltage power systems and DC bus applications.
• Low Impedance: Impedance specified at 28 mΩ, supporting efficient charge/discharge and reduced ripple voltage.
• Ripple Current Capability: 3.23 A at 120 Hz (low frequency) and 3.8 A at 10 kHz (high frequency), enabling reliable operation under continuous ripple stress.
• Wide Temperature Range: Operates from −55°C to +105°C, supporting designs exposed to broad environmental extremes.
• Long Endurance: Rated for 8,000 hours at 105°C, for extended lifetime in high-temperature applications.
• Physical & Mounting: Radial lead mounting with 7.5 mm lead spacing (±0.5 mm), φ18 × 40 mm package case, and polarized construction for correct orientation in circuits.
• Quality & Ratings: AEC-Q200 listed rating and mass-production availability for consistent supply and automotive-grade suitability.

Typical Applications

• Switching Power Supplies: Bulk energy storage and output filtering to stabilize DC rails in compact power converters.
• Automotive Electronics: Power smoothing and decoupling in vehicle control modules and in-vehicle power systems where AEC-Q200 qualification is required.
• Industrial Power Modules: Energy buffering and ripple suppression in industrial converters and motor drive electronics.

Unique Advantages

• High Energy Density: 10,000 µF in a φ18 × 40 mm can provides significant capacitance in a compact radial package, helping reduce board area for bulk storage.
• Robust Ripple Handling: Specified ripple currents at both low and high frequencies deliver predictable performance under continuous AC stress.
• Proven Endurance: 8,000-hour rating at 105°C supports long-term reliability in high-temperature environments.
• Automotive-Grade Rating: AEC-Q200 listing aligns the part with automotive design requirements for qualification and reliability.
• Low Impedance Performance: 28 mΩ impedance helps minimize voltage drop and heat generation under high-current operation.
