UAS2G680MHD6

The UAS2G680MHD6 from Nichicon is a miniature, radial-lead aluminum electrolytic capacitor in the UAS series, offering 68 µF capacitance at a 400 V rating. Designed as a special-type, high-ripple-current component, it targets general-purpose power and electronic designs that require compact energy storage and stability across a wide temperature range.

This part is supplied in bulk/bag packing and is in mass production. Key value propositions include a wide operating temperature range of -40°C to 105°C, specified endurance of 2000 hours at 105°C, and series-level safety features for abnormal overvoltage conditions.

Key Features

• Rated Capacitance & Voltage — 68 µF nominal capacitance with a 400 V rated DC voltage, specified tolerance of -20% to +20% at 120 Hz, 20°C.
• High Ripple Current Capability — Low-frequency ripple current of 360 mA (120 Hz) and high-frequency ripple current of 576 mA (10 kHz), with frequency coefficients provided by the UAS series specifications.
• Wide Temperature Range — Operates from -40°C to 105°C, suitable for designs requiring extended thermal range.
• Endurance — Life/endurance rating of 2000 hours at 105°C under rated voltage and ripple conditions; capacitance, dissipation factor, and leakage current meet the series endurance criteria after test.
• Low Dissipation Factor — tanδ max 0.15 (measured at 120 Hz, 20°C), supporting predictable AC behavior in filtering and smoothing applications.
• Safety Features — UAS series improvements include a pressure relief vent that operates under abnormal conditions to mitigate hazardous outcomes.
• Compact Radial Package — Aluminum can, radial-lead construction with dimensions φ18 × 25 mm and lead spacing 7.5 mm (±0.5 mm), enabling compact PCB layouts in through-hole designs.
• RoHS Compliant — Conforms to RoHS directive requirements for restricted substances.

Typical Applications

• General Purpose Designs — For circuits needing a 68 µF, 400 V radial electrolytic capacitor within a -40°C to 105°C operating window.
• Power Filtering — Suited where specified ripple current handling and low dissipation factor are required under rated conditions.
• High-Voltage DC Bus — Applicable in designs that require 400 V-rated electrolytic capacitance in a compact through-hole package.

Unique Advantages

• High-voltage, compact solution: 400 V rating in a φ18 × 25 mm radial can provides substantial capacitance density for space-constrained through-hole designs.
• Ripple-handling capability: Defined ripple current ratings at 120 Hz and 10 kHz (360 mA and 576 mA) allow designers to size capacitors against real operating ripple stresses.
• Wide thermal endurance: -40°C to 105°C operation and 2000-hour endurance at 105°C support reliable performance in elevated-temperature environments.
• Predictable electrical behavior: Specified tanδ (≤0.15) and clear leakage current formula ensure predictable AC and DC performance for design validation.
• Built-in safety considerations: Series-level safety venting reduces the risk of dangerous failure modes under abnormal overvoltage conditions.
• Regulatory compliance: RoHS-compliant materials simplify regulatory adherence for product assemblies.
