UPM1A331MPD

The UPM1A331MPD is a miniature, high-reliability aluminum electrolytic capacitor in a radial lead can (UPM series) designed for board-level through-hole applications. It delivers 330 µF capacitance at a 10 V rating with low impedance and defined ripple current capability for compact electronic modules.

Targeted at applications requiring extended operating temperature and proven endurance, the UPM1A331MPD combines a small φ8 × 11.5 mm can size with AEC-Q200 qualification and a rated operating range of −55°C to +105°C.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a rated voltage of 10 V and tolerance of −20% to +20%.
• Low Impedance — Specified impedance of 160 mΩ for improved ripple handling in compact packages.
• Ripple Current Performance — Low-frequency ripple current 203 mA (120 Hz) and high-frequency ripple current 350 mA (200 kHz) to support dynamic load conditions.
• Reliability & Endurance — Life rating of 3000 hours at 105°C for the smaller case sizes in the UPM series, with AEC-Q200 qualification noted for the series.
• Temperature Range — Wide operating temperature range from −55°C to +105°C for demanding thermal environments.
• Loss Characteristics — Dissipation factor (tan δ) 0.19 measured at 20°C, 120 Hz for the 10 V variant.
• Packaging & Mounting — Radial lead configuration with 3.5 mm lead spacing (±0.5 mm tolerance); supplied bulk (no terminal forming) or bag packing.
• Leakage Current — Specified leakage current of 99 µA.

Typical Applications

• Automotive electronic modules — AEC-Q200-qualified series and a rated temperature up to +105°C make this part suitable for automotive electronics where reliability and thermal endurance are required.
• Through-hole PCB assemblies — Radial lead package and compact φ8 × 11.5 mm dimensions enable use in space-constrained board-level designs that require a polarized electrolytic capacitor.
• Power management circuits — 330 µF capacitance combined with specified ripple current and low impedance supports bulk capacitance needs in power supply sections and DC filtering.

Unique Advantages

• Compact, high-capacitance form factor: 330 µF in a φ8 × 11.5 mm can reduces board area while providing substantial capacitance for smoothing and energy storage.
• Defined ripple handling: Rated for 203 mA (120 Hz) and 350 mA (200 kHz), enabling predictable performance under both low- and high-frequency ripple conditions.
• High-temperature endurance: 3000-hour life at 105°C for the smaller case sizes provides predictable aging and long-term stability in elevated-temperature environments.
• Automotive-grade qualification: Series-level AEC-Q200 rating supports use in applications that require industry-recognized reliability standards.
• Through-hole ease of assembly: Radial leads with 3.5 mm spacing and standard lead diameter allow straightforward placement and soldering on traditional PCB processes.
• Controlled electrical characteristics: Low impedance (160 mΩ), measured tan δ (0.19 at 120 Hz), and specified leakage current (99 µA) help designers predict circuit behavior.
