UAQ2G680MHD6

The UAQ2G680MHD6 is a radial-leaded aluminum electrolytic capacitor designed for high-voltage, general-purpose power applications. It pairs a 68 µF capacitance with a 400 V rating, offering stable performance across a wide operating temperature range.

Engineered for applications that demand high ripple handling and robust thermal endurance, this component delivers tangible performance characteristics—such as low dissipation factor, specified leakage current, and long life at elevated temperature—that simplify power-filtering and energy-storage design decisions.

Key Features

• Capacitance & Voltage — 68 µF nominal capacitance rated for 400 V DC with ±20% tolerance, providing bulk energy storage and smoothing for high-voltage rails.
• High Ripple Current Capability — Rated for 350 mA at 120 Hz (low frequency) and 560 mA at 10 kHz (high frequency), enabling effective filtering under AC ripple and switching environments.
• Loss and Leakage Characteristics — Maximum tanδ 0.15 (measured at 20°C, 120 Hz) and specified leakage current of 1,188 µA, allowing predictable dissipation and stand-by current behavior.
• Wide Temperature Range & Endurance — Rated for operation from −40°C to +105°C with an endurance specification of 2,000 hours at 105°C under rated DC bias plus rated ripple current.
• Safety Design — Includes pressure relief vent and improved safety features for abnormal voltage conditions as described in the UAQ series specifications.
• Radial Can Package — φ18 × 35.5 mm can size with 7.5 mm lead spacing, radial lead mounting for through-hole designs; available in bulk or bag packing (no terminal forming).
• RoHS Compliant — Conforms to RoHS requirements stated in the product documentation.

Typical Applications

• Power supply filtering — Bulk smoothing and ripple reduction on high-voltage DC rails where 400 V rating and high ripple current capability are required.
• Industrial power electronics — Energy storage and decoupling in industrial inverters, motor drives, and high-voltage control modules that operate across −40°C to +105°C.
• Switching supplies and converters — Output filtering and intermediate bus capacitors for high-voltage switching power supplies that generate significant high-frequency ripple.

Unique Advantages

• High-voltage capability: 400 V rating supports high-voltage rail designs without series stacking, simplifying BOM and layout.
• Documented ripple performance: Separate ripple current ratings for low- and high-frequency conditions (350 mA at 120 Hz, 560 mA at 10 kHz) make it straightforward to size capacitors for both mains and switching environments.
• Thermal endurance: Specified 2,000-hour life at 105°C under rated bias and ripple current provides predictable aging for thermal-stressed applications.
• Predictable electrical loss and leakage: tanδ ≤ 0.15 (20°C, 120 Hz) and specified leakage current enable reliable thermal and standby current budgeting in designs.
• Safety-oriented design: Pressure relief vent and series-level permissible abnormal voltage features reduce hazard risk under abnormal conditions.
• Through-hole, serviceable package: Radial leaded can with 7.5 mm lead spacing supports robust mechanical mounting and ease of replacement or rework.
