UPW1A332MHD

The UPW1A332MHD is a miniature aluminum electrolytic capacitor in a radial‑lead can, designed for low impedance and high reliability in power applications. It delivers 3.3 mF capacitance at a 10 V rating with characteristics tuned for switching power supplies and similar power‑conditioning roles.

With an extended temperature range (−55°C to 105°C), AEC‑Q200 qualification, and a 7000‑hour endurance at 105°C, this part targets applications that require compact bulk capacitance, robust ripple handling, and stable performance over life in demanding environments.

Key Features

• Capacitance & Voltage — 3.3 mF (3300 µF) rated at 10 V, with a tolerance of −20% to +20% for bulk energy storage and smoothing.
• Low Impedance — 60 mΩ impedance supports efficient current flow and reduced voltage drop in high‑duty power circuits.
• High Ripple Capability — Rated ripple current of 1.657 A at 120 Hz and 1.95 A at 10 kHz, enabling effective filtering in switching supplies and high‑frequency power stages.
• Loss Characteristics — Tangent of loss angle (tan δ) 0.23 measured at 20°C, 120 Hz, for predictable dissipation behavior.
• Long Endurance — 7000 hours rated life at 105°C, providing sustained performance in high‑temperature operating conditions.
• Temperature Range — Operates from −55°C to 105°C to accommodate wide environmental extremes.
• Form Factor & Mounting — Radial lead can with diameter φ12.5 mm and length 25 mm; lead spacing 5.0 mm (±0.5 mm) for through‑hole PCB assembly.
• Leakage Current — Specified leakage current of 990 µA for predictable hold and discharge behavior in power circuits.
• Production Status — Mass production availability with packaging options including bulk (no terminal forming) and bag packing.
• Qualification — AEC‑Q200 rated for reliability expectations in applications requiring passive component qualification.

Typical Applications

• Switching Power Supplies — Bulk smoothing and output decoupling where low impedance and high ripple capability reduce voltage ripple and improve regulator stability.
• Automotive Electronics — Suitable for automotive power modules and subsystems that require AEC‑Q200 qualified passive components and wide operating temperature performance.
• Power Conversion Modules — Energy storage and filtering in DC‑DC converters and power management assemblies that demand compact, high‑capacitance solutions.

Unique Advantages

• High Capacitance in a Compact Can — 3300 µF in a φ12.5 × 25 mm package reduces board area for bulk energy storage.
• Improved Power Handling — Low 60 mΩ impedance combined with high ripple currents (1.657 A @120 Hz, 1.95 A @10 kHz) supports robust power conditioning under high load.
• Designed for Harsh Environments — −55°C to 105°C operating range and 7000 hours at 105°C endurance for sustained performance at elevated temperatures.
• Automotive‑Grade Qualification — AEC‑Q200 rating addresses reliability needs for automotive and other demanding applications.
• Through‑Hole Mounting Convenience — Radial lead format with defined 5.0 mm spacing (±0.5 mm) simplifies assembly in traditional PCB layouts and power subassemblies.
• Production Ready — Mass production status and common packaging options (bulk / bag) streamline procurement and prototyping.
