UAQ2G680MHD

The UAQ2G680MHD is a Nichicon aluminum electrolytic capacitor in a radial-lead can, rated 68 µF at 400 V with polarized terminals. It delivers high ripple-current capability, a wide operating temperature range (−40°C to +105°C) and an improved safety feature for abnormally excessive voltage, making it suitable for general-purpose high-voltage circuitry that requires dependable bulk capacitance and smoothing.

Key physical attributes include a φ16×40 mm can (L: 4 × D: 1.6 cm), 7.5 mm lead spacing, and bulk/bag packing. Note: this part is listed with End of Life status.

Key Features

• Capacitance & Voltage — 68 µF nominal capacitance at a rated voltage of 400 V with ±20% tolerance for predictable energy storage in high-voltage applications.
• High Ripple Current — Rated ripple current of 350 mA at 120 Hz (low frequency) and 560 mA at 10 kHz (high frequency) to handle significant AC ripple and improve lifetime under ripple stress.
• Low Loss — Maximum tan δ of 0.15 (measured at rated voltage, 120 Hz, 20°C) to help minimize dissipation in AC conditions.
• Leakage Current — Specified leakage current of 1188 µA at 20°C after 1 minute’s application of rated voltage for predictable quiescent behavior.
• Wide Temperature & Endurance — Operating range from −40°C to +105°C and rated endurance of 2000 hours at 105°C under D.C. bias plus rated ripple current.
• Safety & Reliability — Improved safety feature for abnormally excessive voltage and a pressure relief vent designed to operate without dangerous external effects.
• Form Factor & Mounting — Radial-lead, polarized can (φ16×40 mm), 7.5 mm lead spacing for through-hole PCB mounting and easy handling in bulk/bag packaging.
• RoHS Compliance — Compliant with RoHS directive requirements as stated by the manufacturer.

Typical Applications

• General-purpose power filtering — Bulk energy storage and smoothing in higher-voltage circuits where the 400 V rating and high ripple-current capability are required.
• Industrial power electronics — Use in equipment operating across a wide temperature range (−40°C to +105°C) and subject to significant ripple currents.
• High-voltage smoothing — DC link and filtering stages that need polarized aluminum electrolytic capacity with endurance at elevated temperatures.

Unique Advantages

• High-voltage capability: 400 V rating supports higher-voltage designs without series stacking.
• Designed for ripple stress: Dual ripple-current ratings (350 mA at 120 Hz, 560 mA at 10 kHz) give predictable performance across frequency ranges.
• Wide temperature endurance: −40°C to +105°C operation with 2000 h at 105°C specified lifetime for robust performance in demanding thermal environments.
• Safety features: Improved abnormal-voltage protection and a pressure relief vent help reduce hazardous failure modes.
• Compact radial can: φ16×40 mm footprint with 7.5 mm lead spacing for straightforward through-hole mounting and assembly.
• Regulatory compliance: RoHS-compliant construction for environmental conformity.

Why Choose UAQ2G680MHD?
