UHE1V272MHD

The UHE1V272MHD from Nichicon is a miniature, radial-lead aluminum electrolytic capacitor in the UHE series designed for high reliability and long life. It combines a 2.7 mF capacitance with a 35 V rating in a compact φ16 × 35.5 mm can, intended for general-purpose power applications where low impedance and extended endurance are required.

With a rated temperature range of −40 °C to 105 °C and an endurance of 10,000 hours at 105 °C, this component is optimized for designs that demand stable capacitance, controlled dissipation factor, and strong ripple-current handling in a radial-lead package.

Key Features

• Capacitance & Voltage — 2.7 mF (2700 µF) nominal capacitance with a 35 V rated voltage and capacitance tolerance of ±20% (120 Hz, 20 °C).
• Low Impedance — Rated impedance of 44 mΩ, supporting lower AC voltage drop and improved power-delivery performance.
• High Ripple Current Handling — Low-frequency ripple current 2.888 A (120 Hz) and high-frequency ripple current 3.61 A (10 kHz), enabling robust operation in power-supply and switching environments.
• Dissipation Factor — tan δ = 0.14 measured at 20 °C, 120 Hz, providing a quantified loss characteristic for thermal and stability considerations.
• Long Life & High Reliability — Endurance rated to 10,000 hours at 105 °C, delivering extended operational lifetime in elevated-temperature applications.
• Operating Temperature Range — −40 °C to 105 °C for broad environmental coverage.
• Radial Lead Package — φ16 × 35.5 mm can with 7.5 mm lead spacing (±0.5 mm), provided in bulk/no terminal forming or bag packing.
• Polarized Type & RoHS Compliant — Polarized aluminum electrolytic construction and RoHS-compliant materials.
• Leakage Current — Specified leakage current of 945 µA for leakage budgeting and design validation.

Typical Applications

• Power Supply Filtering — Bulk smoothing and ripple reduction on DC rails where 2.7 mF capacitance and high ripple current ratings are required.
• High-Ripple Power Stages — Use in converter and switching regulator output stages that demand low impedance and strong ripple-current capability up to 3.61 A at 10 kHz.
• Elevated-Temperature Systems — Designs that require continuous operation up to 105 °C and long endurance, benefiting from the 10,000-hour life rating.
• Compact Radial Modules — Applications needing a small radial-lead can (φ16 × 35.5 mm) and 7.5 mm lead spacing for compact power assemblies.

Unique Advantages

• High ripple-current capacity: 3.61 A at 10 kHz and 2.888 A at 120 Hz provide tolerance to significant AC stress on power rails.
• Low ESR/impedance: 44 mΩ impedance helps lower voltage ripple and improve transient response in power systems.
• Long endurance at elevated temperature: 10,000 hours at 105 °C supports extended mean time between maintenance in demanding environments.
• Compact radial form factor: φ16 × 35.5 mm can and 7.5 mm lead spacing enable integration into space-constrained designs without sacrificing capacitance.
• Predictable loss characteristics: Specified tan δ (0.14 at 20 °C, 120 Hz) and leakage current (945 µA) simplify thermal and leakage budgeting during design.
• RoHS compliant: Material compliance for environmental and regulatory alignment.
