UHE1E272MHD6

The Nichicon UHE1E272MHD6 is a miniature, high-reliability aluminum electrolytic capacitor from the UHE series. It is a radial-lead, polar capacitor specified at 2700 µF and 25 V for general-purpose electronic applications.

Designed for demanding operational conditions, the part combines low impedance (60 mΩ) with high ripple handling and long endurance — supporting continuous operation up to 105°C and a rated life of 10,000 hours for its case size and voltage class.

Key Features

• Capacitance & Voltage: 2700 µF nominal capacitance at a rated voltage of 25 V, with a tolerance of -20% to +20% for general-purpose energy storage and decoupling.
• Low Impedance: Specified impedance of 60 mΩ, helping reduce voltage ripple under load and improve power-supply stability.
• High Ripple Current Capability: Low-frequency ripple current 2.344 A (120 Hz) and high-frequency ripple current 2.93 A (10 kHz), supporting both mains-frequency and higher-frequency power environments.
• Thermal Endurance: Rated operating temperature range −40°C to +105°C with a specified life of 10,000 hours at 105°C for this voltage and case size class.
• Electrical Loss and Leakage: Loss tangent (tan δ) of 0.16 (120 Hz, 20°C) and a measured leakage current of 675 µA, allowing predictable behavior in long-term designs.
• Compact Radial Can: Mechanical size φ16 × 25L with 7.5 mm lead spacing (±0.5 mm) and radial lead mounting for through-hole assemblies. Available in bulk or bag packing for production and prototyping.
• Standards & Availability: RoHS compliant and listed as mass production, making it suitable for volume builds with regulatory compliance.

Typical Applications

• Power Supply Filtering: The 2700 µF capacitance, low impedance and high ripple current ratings make this capacitor suitable for smoothing and bulk energy storage in general-purpose power supplies.
• DC Link and Bulk Storage: High ripple capability at both low and high frequencies supports bulk storage and DC link duties in general-purpose electronic systems.
• General-Purpose Electronic Equipment: Robust temperature range (−40°C to +105°C) and 10,000-hour life at 105°C align with requirements for a wide range of industrial and consumer electronics designs.

Unique Advantages

• Long Operational Life: 10,000 hours endurance at 105°C for this voltage/case category supports sustained high-temperature operation and predictable maintenance schedules.
• High Ripple Handling Across Frequencies: Specified ripple currents at 120 Hz and 10 kHz enable reliable performance in both mains-frequency and switching environments.
• Low ESR/Impedance: 60 mΩ impedance helps minimize internal heating and voltage drop under load, improving converter stability and transient response.
• Compact Through-Hole Form Factor: φ16 × 25L radial can with 7.5 mm lead spacing provides a space-efficient solution for through-hole assemblies and retrofit designs.
• Predictable Electrical Characteristics: Measured tan δ (0.16) and specified leakage current (675 µA) give engineers verifiable parameters for margin and reliability calculations.
• Production Ready & RoHS Compliant: Mass-production status and RoHS compliance simplify procurement and regulatory planning for volume designs.
