UHE1V681MHD3

The UHE1V681MHD3 is a Nichicon UHE series aluminum electrolytic capacitor in a radial-lead can, rated at 680 µF and 35 V. It is designed for general-purpose smoothing, decoupling and bulk energy storage where low impedance, long endurance and compact size are required.

As part of the UHE family, this capacitor combines low impedance and high reliability with endurance characteristics specified up to 10,000 hours at elevated temperature, and supports operation across a wide temperature range from −40°C to 105°C.

Key Features

• Rated Value — 680 µF capacitance at 35 V with a tolerance of ±20% (120 Hz, 20°C).
• Low Loss — tanδ = 0.12 (measured at 20°C, 120 Hz) for stable dissipation characteristics in filtering applications.
• Low Impedance — 120 mOhm impedance to minimize voltage drop and support high ripple currents.
• High Ripple Current Capability — 1.455 A at 120 Hz (low frequency) and 1.94 A at 10 kHz (high frequency) for effective ripple handling across common power-conversion frequencies.
• Leakage Current — 238 µA typical leakage after rated voltage application, suitable for general-purpose power circuits.
• Long Endurance — Rated for 10,000 hours at 105°C under DC bias plus rated ripple current as part of the UHE series endurance specification.
• Temperature Range — Operational from −40°C to 105°C to address a wide range of environmental conditions.
• Mechanical & Packaging — Radial lead can (φ16 × 15 mm) with 7.5 mm lead spacing (±0.5 mm); available in bulk (no terminal forming) or bag packing.
• Compliance — RoHS compliant.

Typical Applications

• Power Supply Filtering — Bulk smoothing and output filtering in DC power supplies and switching regulators where high ripple currents are present.
• Industrial Control — Energy storage and decoupling for motor drives, PLCs and control electronics operating across a broad temperature range.
• Consumer & Commercial Electronics — Decoupling and bulk capacitance in audio equipment, appliances and general electronic devices requiring compact radial-lead components.
• Communications Equipment — Filtering and reservoir capacitance for power rails in routers, base stations and other telecom infrastructure equipment.

Unique Advantages

• Low Impedance for Stable Rails — 120 mOhm impedance reduces AC voltage drop and improves transient response in power circuits.
• High Ripple Handling at Multiple Frequencies — Rated ripple currents of 1.455 A (120 Hz) and 1.94 A (10 kHz) accommodate both low- and high-frequency filtering needs.
• Long Life at Elevated Temperature — Endurance specified up to 10,000 hours at 105°C supports designs that require extended reliability under thermal stress.
• Compact Radial Package — φ16 × 15 mm can with 7.5 mm lead spacing offers a small-footprint radial option for through-hole assemblies.
• Clear Electrical Characterization — Specified tanδ, leakage current and tolerance make selection and modeling straightforward for design and simulation.
• RoHS Compliance — Meets environmental directive requirements for lead-free assembly processes.
