UAQ2G330MHD3

The UAQ2G330MHD3 is a radial-lead miniature aluminum electrolytic capacitor from Nichicon's UAQ series. It delivers 33 µF capacitance at a 400 V rating in a compact φ18×20 mm can with 7.5 mm lead spacing, offering a balance of energy storage and high-voltage capability for through-hole power applications.

Designed for extended operation across a wide temperature range and for applications that require elevated ripple handling, the UAQ series includes improved safety features for abnormally excessive voltage and is RoHS compliant. Status: End Of Life — not recommended for new designs.

Key Features

• Capacitance & Voltage — 33 µF rated capacitance at 400 V with a tolerance of −20% to +20%.
• High ripple current capability — Rated low-frequency ripple current 195 mA (120 Hz) and high-frequency ripple current 312 mA (10 kHz).
• Wide operating temperature — Specified for −40°C to +105°C operation with endurance testing of 2000 hours at 105°C under DC bias plus rated ripple current.
• Low dissipation factor — tan δ max 0.15 (measured at 20°C, 120 Hz), supporting stable performance under AC stress.
• Leakage current specification — Product-level leakage current listed as 628 µA; the UAQ series datasheet also provides the leakage current reference formula for verification.
• Safety design — Improved safety features for abnormally excessive voltage and a pressure relief vent that operates under specified conditions.
• Radial can package — φ18 mm diameter, 20 mm length, 7.5 mm lead spacing; available in bulk or bag packing for through-hole assembly.
• RoHS compliant — Conforms to the RoHS directive as documented for the UAQ series.

Typical Applications

• General-purpose power filtering — Energy storage and smoothing in power circuits where a 400 V, 33 µF polarized capacitor is required.
• Power electronics with elevated ripple — Circuits that demand higher ripple-current capability at both low and high frequencies.
• Maintenance and replacement — Supply for repair, sustaining engineering, or legacy designs originally specified with UAQ-series components.

Unique Advantages

• High ripple-current handling: Explicit ripple ratings at 120 Hz and 10 kHz allow designers to size for AC stress across frequency ranges.
• Elevated-temperature endurance: 2000 hours at 105°C under rated conditions provides predictable lifetime behavior for applications exposed to heat.
• Safety-focused construction: UAQ series improvements for abnormal voltage conditions and a pressure relief vent enhance operational safety.
• Compact through-hole form factor: φ18×20 mm can with 7.5 mm lead spacing fits common radial PCB layouts for easy replacement or retrofitting.
• Regulatory compliance: RoHS conformity supports use in regions requiring restricted-substance compliance.
