UPM2A331MHD

The UPM2A331MHD is a radial lead aluminum electrolytic capacitor from Nichicon’s UPM series, offering 330 µF capacitance at a 100 V rating with ±20% tolerance. It is a high-reliability, low-impedance can-type capacitor designed for mass production with bulk (no terminal forming) bag packing.

Engineered for demanding environments, this AEC-Q200 qualified part supports automotive applications with a wide operating range from −55 °C to 105 °C and long-term endurance—5,000 hours at 105 °C for applicable case sizes—making it suitable for power supply smoothing, decoupling and energy reservoir roles in vehicle electronics and similar systems.

Key Features

• Electrical Performance — 330 µF nominal capacitance at 100 V DC with ±20% tolerance, providing bulk energy storage and decoupling capability.
• Low Impedance — Specified impedance of 62 mΩ, supporting lower ripple and better filtering performance in power circuits.
• Ripple Current Ratings — Rated ripple current of 794.6 mA at 120 Hz and 1.37 A at 200 kHz, enabling use under AC ripple conditions typical of power conversion stages.
• High Reliability & Endurance — Designed for 5,000 hours load life at 105 °C (as applicable by case size) to support long-term operation in elevated-temperature environments.
• Automotive Qualification — AEC-Q200 qualified for use in automotive electronic systems.
• Wide Temperature Range — Specified operating range from −55 °C to 105 °C for reliable operation across typical automotive temperature extremes.
• Form Factor & Mounting — Radial lead can with lead spacing of 7.5 mm and overall dimensions L: 30.5 mm × D: 16 mm (height/seated max 30.5 mm), suitable for through‑hole PCB mounting.
• Polarized Design — Polarized aluminum electrolytic construction for DC energy storage and smoothing applications.
• Regulatory Compliance & Packing — RoHS compliant and supplied in bulk bag packing for mass production assembly workflows.

Typical Applications

• Automotive Power Electronics — Smoothing and filtering in vehicle power supplies, converters and inverters where 100 V rating and low impedance are required.
• Engine Control Units (ECUs) and Control Modules — Energy reservoir and decoupling for MCU power rails and control electronics operating across −55 °C to 105 °C.
• In‑vehicle Power Conversion & Motor Drive Filtering — Bulk capacitance and ripple handling for DC link and intermediate circuits in motor control and power conversion systems.

Unique Advantages

• High-voltage capability: 100 V rating supports higher-voltage subsystems without requiring series stacking.
• Long life at elevated temperature: 5,000 hours endurance at 105 °C (where applicable) reduces maintenance and replacement frequency in demanding environments.
• Low-impedance performance: 62 mΩ impedance helps minimize voltage ripple and heat generation in high-current ripple conditions.
• Automotive-grade qualification: AEC-Q200 status provides qualification confidence for automotive electronic designs.
• Compact radial package: 30.5 mm × 16 mm can size with 7.5 mm lead spacing fits common through-hole layouts while delivering substantial capacitance.
• Production-friendly packing: Bulk bag packing (no terminal forming) supports high-volume assembly processes.
