UHE1C681MPD

The UHE1C681MPD is a miniature, high-reliability aluminum electrolytic capacitor in a radial-lead can package from Nichicon's UHE series. It delivers 680 µF capacitance at a 16 V rating with a compact φ8 × 20 mm footprint and 3.5 mm lead spacing for through-hole mounting.

Designed for general-purpose applications that require a compact electrolytic with long endurance and low impedance, the part offers specified ripple-handling, low loss (tanδ), wide operating temperature range, and a 7000-hour life rating at 105°C.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance with a rated voltage of 16 V and tolerance of -20% to +20%.
• Miniature, Radial Package — φ8 × 20 mm can size with radial lead configuration and 3.5 mm lead spacing (±0.5 mm tolerance) for compact through-hole layouts.
• Low Impedance — Rated impedance of 270 mΩ supports lower ripple voltage in compact form factors.
• Loss Characteristics — Tangent of loss angle (tanδ) of 0.16 measured at 20°C, 120 Hz (16 V rating).
• Ripple Current Ratings — Low-frequency ripple current 787.5 mA at 120 Hz and high-frequency ripple current 1.05 A at 10 kHz, enabling handling of both low- and high-frequency ripple components.
• Leakage Current — Specified leakage current of 108.8 µA after rated voltage application.
• High Endurance — Life/endurance rating of 7000 hours at 105°C under DC bias plus rated ripple current, consistent with the UHE series' high-reliability focus.
• Wide Temperature Range — Operating range from -40°C to +105°C for use across varied thermal environments.
• Compliance & Packaging — RoHS-compliant; available in bulk (no terminal forming) or bag packing for volume assembly and prototyping.

Typical Applications

• General-Purpose Electronics — Compact radial format and 16 V/680 µF rating suit a wide range of board-level functions where a reliable electrolytic capacitor is needed.
• Power Module Subcircuits — 270 mΩ impedance and specified ripple currents (787.5 mA @120 Hz, 1.05 A @10 kHz) support power-related roles in small power supplies and local energy storage.
• Extended-Temperature Designs — Rated for -40°C to +105°C and 7000 hours at 105°C, making it appropriate for designs requiring sustained operation at elevated temperatures.

Unique Advantages

• Compact High-Capacitance Footprint: 680 µF in a φ8 × 20 mm can provides sizable capacitance where board space is limited.
• Long Endurance at Elevated Temperature: 7000-hour life at 105°C supports designs requiring prolonged reliability under thermal stress.
• Balanced Ripple Performance: Separate low-frequency and high-frequency ripple current specifications enable predictable behavior across common ripple spectra.
• Low Loss for Stable Performance: tanδ of 0.16 (20°C, 120 Hz) contributes to predictable AC loss and thermal behavior in circuit designs.
• Through-Hole Compatibility: Radial leads with 3.5 mm spacing simplify mounting in conventional through-hole PCBs and prototyping fixtures.
• Regulatory Compliance: RoHS-compliant construction supports use in assemblies requiring restricted-substance conformity.
