UPW1H182MHD

The UPW1H182MHD is a miniature, low-impedance aluminum electrolytic capacitor in a radial-can package designed for power filtering and energy storage. With a rated capacitance of 1800 µF at 50 V and a wide operating temperature range, it targets switching power supplies and other power electronics where high ripple handling, long life, and reliable performance are required.

Key Features

• Capacitance & Voltage — 1800 µF nominal capacitance with a 50 V rated voltage and ±20% tolerance, providing bulk energy storage for DC link and smoothing applications.
• Low Impedance — 50 mΩ impedance, enabling effective filtering and stable voltage under load for switching power systems.
• High Ripple Current Capability — Rated ripple current of 2.55 A at 120 Hz and 3.00 A at 10 kHz to support high-frequency switching applications.
• Long Endurance — 8000 hours rated lifetime at 105°C when operated under specified conditions, supporting sustained operation in elevated temperatures.
• Wide Temperature Range — Specified for −55°C to +105°C operation to accommodate a broad set of environmental conditions.
• Package & Mounting — Radial lead, can-style package with 7.5 mm lead spacing and compact dimensions (φ18 × 30.5 mm), suited for through-hole assemblies and bulk packing.
• Loss Characteristics — Tangent of loss angle (tan δ) of 0.10 (measured at 120 Hz, 20°C), aligning with the series’ low-loss design for larger capacitances.
• AEC Qualification — AEC-Q200 rated, indicating suitability for designs requiring that qualification level.

Typical Applications

• Switching Power Supplies — Bulk smoothing and output filtering to reduce ripple and stabilize voltages in power converters.
• Industrial Power Electronics — Energy buffering and decoupling in motor drives, inverters, and control power rails where high ripple current and temperature endurance are needed.
• Automotive Electronics — Power filtering and decoupling in automotive electronic modules, leveraging AEC-Q200 qualification and wide temperature range.

Unique Advantages

• High Ripple Endurance: Rated ripple currents of 2.55 A (120 Hz) and 3.00 A (10 kHz) let you handle both low- and high-frequency switching stress without frequent replacements.
• Low Impedance Performance: 50 mΩ impedance improves transient response and reduces conduction losses in power pathways.
• Extended High‑Temperature Life: 8000 hours at 105°C supports long-term reliability in thermally demanding installations.
• Compact Radial Can: φ18 × 30.5 mm package with 7.5 mm lead spacing delivers high capacitance in a space-efficient, through-hole form factor.
• Broad Operating Range: −55°C to +105°C rating enables use across a wide set of environmental conditions.
• Industry Qualification: AEC-Q200 rating provides an added level of assurance for applications where that qualification is required.
