UAQ2G470MHD6

The UAQ2G470MHD6 is a radial-lead aluminum electrolytic capacitor specified at 47 µF and 400 V. It is part of Nichicon’s UAQ series, designed as a high-ripple-current, wide-temperature-range electrolytic solution for general-purpose applications.

Key attributes include a wide operating temperature range of -40°C to +105°C, a rated lifetime of 2000 hours at 105°C, an improved safety vent feature for abnormal overvoltage conditions, and RoHS compliance. Note: this series is scheduled for discontinuation and is not recommended for new designs.

Key Features

• Capacitance & Voltage: 47 µF nominal capacitance at a 400 V rated voltage, with ±20% tolerance.
• High Ripple Current Capability: Rated ripple current of 280 mA at 120 Hz and 448 mA at 10 kHz to address demanding AC ripple conditions.
• Low Loss Tangent: Maximum tan δ of 0.15 (measured at 120 Hz, 20°C), supporting stable performance under AC stress.
• Leakage Current: Leakage performance characterized at 852 µA (product specification per part data).
• Thermal Endurance: Rated for 2000 hours at 105°C under D.C. bias plus rated ripple current, with specified limits on capacitance change, tan δ, and leakage after endurance testing.
• Wide Operating Temperature: Specified operation from -40°C to +105°C for broad environmental compatibility.
• Radial Leaded Can Package: φ18 × 25 mm can with 7.5 mm lead spacing in a through-hole radial-lead format for straightforward PCB mounting and replacement.
• Safety Vent: Pressure relief vent design intended to operate without dangerous outcomes such as flames or case fragmentation under abnormal conditions.
• Regulatory Compliance: RoHS-compliant construction.

Typical Applications

• General Purpose: Specified for general-purpose uses requiring a 47 µF, 400 V electrolytic capacitor with wide temperature range and high ripple capability.
• General Purpose: Suitable where long-duration high-temperature endurance (2000 h at 105°C) is required in maintenance or replacement scenarios.
• General Purpose: Fits through-hole radial-lead designs that require a φ18 × 25 mm can with 7.5 mm lead spacing and polarized capacitor characteristics.

Unique Advantages

• High ripple-current rating: Supports substantial ripple current at both low and high frequencies, reducing stress on power systems within its rated limits.
• Wide temperature range and endurance: -40°C to +105°C operation and 2000-hour endurance at 105°C provide predictable performance in elevated-temperature environments.
• Safety-focused design: Built-in pressure relief vent reduces the risk of hazardous failure modes under abnormal voltage conditions.
• Through-hole radial format: Standard φ18×25 mm can and 7.5 mm lead spacing simplify replacement and repair in existing assemblies.
• RoHS compliant: Meets RoHS directive requirements noted in the product information.
