UPM1H122MHD6

The UPM1H122MHD6 is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon’s UPM series designed for high-reliability power applications. It delivers 1.2 mF capacitance at 50 V in a compact φ18 × 30.5 mm can with 7.5 mm lead spacing.

Targeted for demanding environments, this component combines low impedance and high ripple-handling capability with long endurance at elevated temperature, making it suitable for robust power-smoothing and energy-buffering tasks in automotive and industrial designs.

Key Features

• Capacitance & Voltage: 1.2 mF (1200 µF) rated at 50 V with ±20% tolerance for bulk energy storage and decoupling in power rails.
• Low Impedance & Ripple Performance: Rated impedance 31 mΩ and ripple current up to 1.542 A at 120 Hz (low frequency) and 1.88 A at 200 kHz (high frequency), enabling effective smoothing under dynamic loads.
• High Reliability Endurance: 5000 hours load life at +105°C, supporting long-term operation in elevated-temperature environments.
• Wide Operating Temperature: −55°C to +105°C operating range for use across a broad set of environmental conditions.
• Automotive-Grade Qualification: AEC-Q200 rating for designs that require automotive reliability standards.
• Compact Radial Package: φ18 × 30.5 mm can, radial lead mounting with 7.5 mm lead spacing (±0.5 mm), available bulk or bag packed for flexible assembly workflows.
• Leakage & Loss Characteristics: Specified leakage current 1800 µA and tanδ 0.1 (measured at 20°C, 120 Hz), suitable for predictable power-system behavior.
• Compliance: RoHS compliant to support regulatory requirements for electronic assemblies.

Typical Applications

• Automotive Power Systems: Energy buffering and smoothing in power rails where AEC-Q200 qualification and high-temperature endurance are required.
• DC–DC Converters and Power Supplies: Bulk capacitance and high ripple-current capability help reduce voltage ripple and stabilize converters under transient loads.
• Industrial Control Electronics: Robust operation across −55°C to +105°C and long life at elevated temperature make it suitable for industrial power modules and controllers.
• Embedded Systems and Backup Power: Compact radial can provides reliable energy storage for hold-up and filtering in compact assemblies.

Unique Advantages

• Proven High-Temperature Endurance: 5000-hour rating at +105°C reduces maintenance and replacement frequency in hot environments.
• Strong Ripple Handling: Specified ripple currents at both low and high frequency allow designers to address a range of switching and line-frequency conditions without overstressing the capacitor.
• Low Series Impedance: 31 mΩ impedance supports lower ESR-related losses and improved transient response in power stages.
• Automotive-Grade Confidence: AEC-Q200 qualification provides a documented reliability baseline for automotive and similarly demanding applications.
• Compact, Through-Hole Form Factor: Radial lead, can-style package with standard lead spacing simplifies mechanical retention and replacement in through-hole assemblies.
• Regulatory Compliance: RoHS compliance supports use in assemblies requiring restricted-substance conformance.
