UPM1K331MHD

The UPM1K331MHD is an aluminum electrolytic capacitor from Nichicon’s UPM series, configured as a radial-lead, can-style capacitor for high-reliability applications. It delivers 330 µF at an 80 V rating with low impedance and long-life endurance characteristics.

Designed for demanding environments, this AEC-Q200 qualified unit and RoHS-compliant part is targeted at automotive and other high-reliability power electronics where sustained performance up to 105°C and robust ripple handling are required.

Key Features

• Capacitance & Voltage — 330 µF capacitance with an 80 V rated voltage, suitable for high-voltage smoothing and energy storage in applicable designs.
• Low Impedance — Specified impedance of 88 mΩ, supporting improved transient response and reduced power loss in filter networks.
• Long Life at Elevated Temperature — Rated for 5000 hours at 105°C, enabling extended field life in high-temperature operating conditions.
• Wide Operating Temperature Range — Operates from −55°C to +105°C, matching typical requirements for harsh environments.
• Ripple Current Capability — Handles 638 mA at 120 Hz and 1.1 A at 200 kHz, allowing effective handling of both low- and high-frequency ripple currents.
• AEC-Q200 Qualified — Automotive-grade qualification for designs that require validated reliability.
• Radial Lead Package — Radial, can package with 5 mm lead spacing for through-hole mounting and straightforward assembly; supplied in bulk bag packing for mass production.
• Polarized with Standard Tolerance — Polarized capacitor with ±20% capacitance tolerance at 120 Hz, 20°C.

Typical Applications

• Automotive power electronics — Energy storage and smoothing in 80 V systems where AEC-Q200 qualification and 5000 h endurance at 105°C support reliable operation.
• In-vehicle DC–DC converters — Input/output filtering and decoupling benefiting from low impedance (88 mΩ) and specified ripple current capabilities.
• Motor drive and inverter support — Bulk smoothing for power stages that require high-voltage capacitance and elevated-temperature endurance.

Unique Advantages

• Durability in high-temperature environments — 5000-hour life at 105°C provides predictable long-term performance for heat-exposed systems.
• Improved electrical performance — Low impedance specification helps reduce voltage ripple and improve transient behavior in power circuits.
• High ripple handling — Explicit ripple current ratings at both 120 Hz and 200 kHz accommodate mixed-frequency power designs.
• Automotive-grade qualification — AEC-Q200 rating supports use in vehicle electronics and other high-reliability applications.
• Production-ready packaging — Supplied in bulk (bag) packing for mass production assembly workflows.
• Regulatory compliance — RoHS-compliant construction for global regulatory requirements.
