UHE1V681MPD

The UHE1V681MPD is a Nichicon UHE-series miniature aluminum electrolytic capacitor in a radial-lead package designed for general-purpose electronic applications. It combines a compact φ10 × 30.5 mm can with a 680 µF capacitance and a 35 V rated voltage to address common power filtering, decoupling and energy-storage needs in through-hole designs.

As part of Nichicon’s UHE family, this part emphasizes low impedance and high reliability, with a rated endurance of 7000 hours at 105°C and RoHS compliance for environmental conformity.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance with a 35 V rated voltage and a tolerance of −20% to +20%.
• Low impedance — Rated impedance of 120 mΩ to support stable bulk capacitance performance in power circuits.
• High ripple current capability — Low-frequency ripple current 1.433 A (120 Hz) and high-frequency ripple current 1.91 A (10 kHz), enabling robust handling of AC stress on power rails.
• Loss and leakage — Tangent of loss angle (tan δ) 0.12 (20°C, 120 Hz) and leakage current specified at 238 µA.
• Long-life, high-reliability design — Rated for 7000 hours at 105°C; the UHE series is specified for low impedance and high reliability with endurance ranges from 6000 to 10000 hours depending on rating and case size.
• Compact radial-lead package — φ10 × 30.5 mm can, radial lead mounting with 5 mm lead spacing (±0.5 mm), available in bulk or bag packing for flexible assembly handling.
• Operating range — Specified for −40°C to +105°C to cover a wide range of operating environments.
• Regulatory — RoHS compliant.

Typical Applications

• General-purpose electronics — Suitable for general-purpose capacitor roles in through‑hole designs where bulk capacitance and reliable ripple handling are required.
• Power supply filtering — Used for smoothing and decoupling on DC power rails requiring 680 µF at up to 35 V.
• Energy storage and buffering — Provides short-term energy buffering for circuits that need compact, high-capacitance components.

Unique Advantages

• High ripple tolerance: Rated ripple currents of 1.433 A (120 Hz) and 1.91 A (10 kHz) reduce thermal stress under AC loading.
• Compact footprint: φ10 × 30.5 mm radial can delivers 680 µF in a small through-hole package for space-constrained PCBs.
• Long operational life: 7000 hours at 105°C provides predictable end-of-life behavior for long-term designs.
• Low impedance: 120 mΩ nominal impedance supports stable voltage smoothing and improved transient response.
• Through-hole mechanical robustness: Radial lead package with 5 mm lead spacing simplifies mounting and mechanical retention in assembled boards.
• RoHS compliant: Conforms to environmental requirements for lead‑free designs.
