UAQ2G470MRD3

The UAQ2G470MRD3 is a radial-lead aluminum electrolytic capacitor rated at 47 µF and 400 V. It is a polarized, high-ripple-current component designed for general-purpose use where a compact, high-voltage electrolytic is required.

This part offers a wide operating temperature range of -40°C to 105°C and a rated lifetime of 2000 hours at 105°C. Note: this product is listed with End of Life status—verify availability before specifying.

Key Features

• Capacitance & Voltage: 47 µF nominal capacitance with a 400 V rated voltage and ±20% tolerance, suitable for high-voltage polarized applications.
• High Ripple Current Capability: Rated ripple current of 280 mA at 120 Hz (low frequency) and 448 mA at 10 kHz (high frequency), with frequency coefficients defined in the UAQ series.
• Wide Temperature Range & Endurance: Operates from -40°C to 105°C and meets endurance requirements after 2000 hours at 105°C with specified DC bias plus rated ripple current.
• Low Loss & Leakage: Maximum tanδ 0.15 and measured leakage current consistent with product data (specified leakage current listed as 852 µA for this part).
• Safety & Construction: Improved safety feature for abnormal voltage and a pressure relief vent to reduce hazardous conditions; printed white marking on a dark brown sleeve for polarity and identification.
• Package & Mounting: Radial, can-style package with φ22 × 20L dimension, 10 mm lead spacing, and bulk/bag packaging for through-hole assembly.
• Compliance: RoHS compliant per the product information.

Typical Applications

• General-purpose power designs: Use where a polarized 47 µF, 400 V electrolytic capacitor is required for high-voltage smoothing or energy storage in through-hole assemblies.
• High-ripple environments: Applicable in designs that require elevated ripple current handling within the UAQ series rated values.
• Wide-temperature systems: Suitable for equipment operating across a -40°C to 105°C ambient range, matching the part’s rated temperature limits.

Unique Advantages

• High-voltage capability: 400 V rating enables use in higher-voltage power rails while keeping component count low.
• Designed for ripple endurance: Specified ripple current ratings at both low and high frequencies support sustained AC stress per the datasheet values.
• Wide operating temperature and proven lifetime: Rated for -40°C to 105°C with a 2000-hour endurance at 105°C, supporting thermal reliability requirements.
• Built-in safety measures: Pressure relief vent and improved abnormal-voltage tolerance minimize hazardous failure modes under specified conditions.
• RoHS compliant: Meets RoHS directive requirements as noted in the product information.
• Through-hole-friendly package: Radial can with 10 mm lead spacing and bulk/bag packaging simplifies handling and assembly for legacy and repairable designs.
