UHE1E681MPD

The UHE1E681MPD is a Nichicon UHE series aluminum electrolytic capacitor in a compact radial‑lead can. It provides 680 µF capacitance at a 25 V rating with low impedance and long life characteristics targeted for general‑purpose electronic designs.

Engineered for applications requiring bulk energy storage and smoothing in a small footprint, the part combines a radial can package, a narrow 5 mm lead spacing and a temperature range of −40°C to +105°C to support reliable operation in a variety of assemblies.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance at a 25 V rated voltage, with a tolerance of −20%/+20%.
• Low Impedance — Specified impedance of 180 mΩ, supporting effective ripple handling and transient response.
• Long Life — Rated lifetime of 7000 hours at 105°C; series literature indicates endurance characteristics across 6000–10000 hours depending on conditions.
• Ripple Current Capability — Rated ripple current of 1.05 A at 120 Hz and 1.4 A at 10 kHz to accommodate AC ripple and switching environments.
• Compact Radial Package — Radial lead, can package with 5 mm lead spacing and a seated height up to 2 cm, physical size L: 2 × D: 1 cm for tight PCB layouts.
• Operating Temperature — Wide operating range from −40°C to +105°C for use across varied ambient conditions.
• Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑Purpose Power Supply Smoothing — Bulk capacitance for smoothing and energy storage in low‑voltage power rails where a compact radial electrolytic is required.
• Decoupling and Local Energy Buffering — Low impedance and defined ripple current ratings make it suitable for decoupling near regulators and converters in compact assemblies.
• Consumer and Industrial Electronics — Small footprint and long life at 105°C support use in space‑constrained boards and general‑purpose electronic equipment.

Unique Advantages

• Space‑Efficient Energy Storage: 680 µF in a 2 × 1 cm footprint and radial can package minimizes board area for bulk capacitance requirements.
• Improved Ripple Handling: Low impedance (180 mΩ) combined with specified ripple currents at 120 Hz and 10 kHz helps maintain voltage stability under AC ripple and switching loads.
• Design for Reliability: Rated 7000 hours at 105°C with series endurance data supporting extended operation, reducing the need for early field replacement.
• Easy Through‑Hole Integration: Radial lead configuration with 5 mm lead spacing simplifies PCB layout and manual or wave solder assembly processes.
• Wide Temperature Range: −40°C to +105°C operation enables deployment across varied thermal environments without additional thermal derating details.
• Regulatory Compliance: RoHS compliance supports use in designs targeting restricted‑substance requirements in many markets.
