UAS2G470MHD6

The UAS2G470MHD6 is a radial-lead aluminum electrolytic capacitor in Nichicon’s UAS series, offering 47 µF capacitance at a 400 V rating. It combines a compact radial can package (φ18 × 20 mm) with a wide operating temperature range and rated endurance for general-purpose electronics.

Designed for applications that require high ripple tolerance and long-term stability, this capacitor delivers measurable performance: 280 mA ripple at 120 Hz, 448 mA at 10 kHz, tan δ ≤ 0.15, and a 2000-hour lifetime at 105 °C. The product is RoHS compliant and includes safety features for abnormal voltage conditions.

Key Features

• Rated Performance — 47 µF capacitance at a 400 V DC rating with ±20% tolerance, suitable for high-voltage polarized applications.
• High Ripple Current Handling — Rated ripple current of 280 mA at 120 Hz and 448 mA at 10 kHz, supporting applications with significant AC ripple components.
• Wide Temperature Range — Operates from –40 °C to +105 °C, enabling use across varied environmental conditions.
• Endurance and Reliability — Specified for 2000 hours at 105 °C under DC bias plus rated ripple current, with defined limits for capacitance change, tan δ, and leakage current after endurance testing.
• Safety Features — Designed with an improved safety feature for abnormally excessive voltage and a pressure relief vent to minimize hazardous failure modes.
• Compact Radial Can Package — φ18 × 20 mm can with 7.5 mm lead spacing and radial lead mounting for through-hole assemblies and bulk/bag packaging for volume production.
• Leakage and Loss Characteristics — Specified leakage current of 852 µA and tan δ up to 0.15, supporting predictable performance in system designs.
• Regulatory — RoHS compliant for restricted substances control.

Typical Applications

• General Purpose Electronics — Suitable where a polarized 47 µF, 400 V capacitor with wide temperature tolerance and measurable ripple capability is required.
• Power Supply Filtering — Used for smoothing and decoupling in high-voltage circuits where rated ripple current and low loss (tan δ ≤ 0.15) are important design considerations.
• Industrial and Commercial Equipment — Applicable in systems that demand endurance at elevated temperatures (2000 h at 105 °C) and safety features for abnormal voltage events.

Unique Advantages

• High-voltage capability: 400 V rating enables use in higher-voltage power rails without series stacking.
• Measured ripple performance: Explicit ripple ratings at 120 Hz and 10 kHz let designers size capacitors against AC stress with confidence.
• Long-term thermal endurance: 2000-hour qualification at 105 °C supports longevity in thermally demanding designs.
• Safety-minded construction: Pressure relief vent and improved abnormal-voltage protections reduce the risk of hazardous failures.
• Compact, serviceable package: φ18 × 20 mm radial can with 7.5 mm lead spacing simplifies through-hole assembly and replacement in production assemblies.
• Compliance: RoHS status supports regulatory and environmental requirements for commercial products.
