URS2G470MHD

The URS2G470MHD is a miniature, radial-lead aluminum electrolytic capacitor in Nichicon’s URS series, designed for general-purpose power electronics. Its polarized radial-can construction and compact φ18×25 mm footprint provide a space-efficient solution for high-voltage filtering and energy-storage roles where through-hole mounting is preferred.

With a 47 µF capacitance at a 400 V rating, defined ripple-current capability and an operating range from −40°C to 85°C, this part targets applications that require stable capacitance, measurable loss characteristics, and predictable endurance under elevated temperature stress.

Key Features

• Capacitance and Tolerance — 47 µF nominal capacitance with tolerance −20% to +20% for predictable filtering and decoupling performance.
• High Rated Voltage — 400 V rated voltage suitable for higher-voltage DC bus and power supply circuits that require elevated voltage margin.
• Radial, Through‑Hole Package — Radial lead configuration with 7.5 mm lead spacing (±0.5 mm) for straightforward PCB placement and secure soldered connections.
• Compact Can Size — Case diameter φ18 mm and length 25 mm provide a low-profile option for space-constrained designs.
• Loss and Leakage Characteristics — Tangent of loss angle (tan δ) of 0.25 measured at 20°C, 120 Hz, and a specified leakage current of 852 µA for design verification and quality control.
• Ripple Current Capability — Low-frequency ripple current of 420 mA at 120 Hz and high-frequency ripple current of 672 mA at 10 kHz, enabling handling of both mains-frequency and higher-frequency ripple components.
• Endurance and Temperature Range — Rated for 2000 hours at 85°C and an operating temperature range from −40°C to +85°C for reliable performance in elevated-temperature environments.
• Packaging Options — Supplied in bulk (no terminal forming) or bag packing to support different assembly workflows.

Typical Applications

• High‑voltage power supplies — Bulk smoothing and DC bus support where a 400 V rating and 47 µF capacitance provide energy storage and ripple attenuation.
• Industrial power conversion — Filtering and decoupling in converters and inverters that require robust ripple-current handling and elevated voltage capability.
• General-purpose electronic equipment — Through-hole radial mounting for retrofit, repair, and designs favoring discrete component replacement and mechanical robustness.

Unique Advantages

• Elevated voltage capability: 400 V rating enables use in higher-voltage DC circuits without needing series stacking of lower-voltage parts.
• Compact footprint: φ18×25 mm can reduces board space compared with larger radial cans while maintaining required capacitance.
• Defined ripple performance: Specified low- and high-frequency ripple currents (420 mA @120 Hz, 672 mA @10 kHz) help designers size capacitors for expected AC stress.
• Measurable electrical characteristics: Specified tan δ (0.25 at 20°C, 120 Hz) and leakage current (852 µA) aid in component selection and end-of-line testing.
• Through‑hole reliability: Radial lead can construction and 7.5 mm lead spacing simplify mechanical retention and solder joint reliability in assembled products.
• Thermal endurance: 2000 hours at 85°C rating provides a defined life expectation for designs subject to sustained elevated temperatures.
