UAS2G680MHD

The UAS2G680MHD is a radial-lead aluminum electrolytic capacitor in Nichicon’s UAS series, specified at 68 µF and 400 V with a ±20% tolerance. It is a miniature, polarized can-type capacitor engineered for general-purpose electronic applications requiring high ripple capability and wide operating temperature.

Designed for use across demanding environments, the part combines high ripple current ratings, a wide −40°C to +105°C operating range, and a 2000 hour endurance at 105°C to deliver consistent performance in assemblies that require robust DC voltage filtering and energy storage.

Key Features

• Capacitance & Voltage — 68 µF rated capacitance at 400 V provides bulk energy storage for DC circuits in a compact φ16 × 35.5 mm can.
• High Ripple Current — Rated ripple current of 385 mA at 120 Hz (low frequency) and 616 mA at 10 kHz (high frequency) supports designs with significant AC ripple components.
• Wide Temperature Range — Specified for −40°C to +105°C operation, enabling use in a variety of ambient conditions.
• Endurance — 2000 hours life at 105°C under D.C. bias plus rated ripple current ensures long-term stability in elevated-temperature applications.
• Low Loss Tangent — tan δ maximum of 0.15 at rated voltage helps minimize dissipation and heating under normal operation.
• Leakage Current — Leakage current specified at 1188 µA, with datasheet guidance for measurement (0.04CV + 100 µA formula) after 1 minute at 20°C.
• Safety Design — Series-level features include an improved safety vent for abnormal over-voltage conditions and a pressure relief vent to reduce risk of dangerous failure modes.
• Radial Lead Package — φ16 × 35.5 mm can with 7.5 mm lead spacing and radial lead mounting for through-hole assemblies; supplied in bulk/bag packaging for mass production.
• RoHS Compliant — Meets RoHS directives, supporting environmentally conscious designs.

Typical Applications

• General-purpose electronic equipment — Use in designs that require a compact 400 V polarized capacitor with reliable ripple handling and wide temperature tolerance.
• Power supply modules — Suitable for DC filtering and bulk energy storage where 400 V rating and high ripple current are required.
• Industrial power control — Applicable to control and conversion equipment demanding endurance at elevated temperatures and robust safety behavior under abnormal voltage conditions.

Unique Advantages

• High-voltage, compact form factor: 400 V rating in a φ16 × 35.5 mm can provides dense energy storage for space-constrained designs.
• Elevated ripple capability: Dual ripple ratings (385 mA at 120 Hz and 616 mA at 10 kHz) support both low- and high-frequency ripple environments.
• Wide operating temperature and proven endurance: −40°C to +105°C range and 2000 hour life at 105°C help ensure stable performance in harsh conditions.
• Safety-oriented design: Improved abnormal-voltage safety features and a pressure relief vent reduce the risk profile in over-voltage events.
• Through-hole radial mounting: 7.5 mm lead spacing and standard radial can packaging simplify integration into legacy and production PCBs.
• Regulatory compliance: RoHS compliance supports modern environmental requirements without sacrificing performance.
