URS2G470MRD6

The URS2G470MRD6 is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon's URS series. It delivers 47 µF capacitance at a 400 V rated voltage in a compact radial can package designed for general-purpose electronic applications.

Engineered for space-constrained assemblies, this polarized capacitor combines a high-voltage rating with defined ripple performance and a proven endurance specification to support dependable power filtering and energy storage in a variety of equipment.

Key Features

• Electrical: 47 µF, 400 V — Provides bulk capacitance and high-voltage capability suitable for mid- to high-voltage circuits where a compact electrolytic capacitor is required.
• Radial can package — Radial lead mounting with a 1 cm lead spacing and a can-style package simplifies through-hole assembly and mechanical retention on PCB layouts.
• Compact dimensions — Size L × D: 2 cm × 2 cm with a seated height maximum of 2 cm, enabling integration into low-profile board designs.
• Polarized device, ±20% tolerance — Standard polarization and ±20% capacitance tolerance for predictable behavior in DC filtering and energy storage applications.
• Operating temperature and endurance — Rated for −40 °C to +85 °C with an endurance of 2000 hours at 85 °C, supporting consistent performance in environments within that range.
• Ripple current performance — Specified ripple current of 420 mA at 120 Hz and 672 mA at 10 kHz; frequency coefficients for 47 µF support increased ripple capability at higher frequencies.
• Leakage current specification — Series leakage current defined by the datasheet test method (e.g., not more than 0.03CV µA after 1 minute), providing predictable leakage characteristics for design calculations.

Typical Applications

• Power supply filtering — Bulk smoothing and DC link support where 400 V rating and 47 µF capacitance are required to stabilize bus voltages.
• Power conversion circuitry — Energy storage and decoupling in power converters and high-voltage supply stages within the stated temperature and endurance limits.
• Industrial and general-purpose electronics — General-purpose use in equipment requiring a compact, high-voltage electrolytic capacitor for filtering and transient suppression.

Unique Advantages

• High-voltage capability: 400 V rating allows use in higher-voltage circuits without increasing capacitor volume.
• Compact, low-profile footprint: 2 cm × 2 cm can size and radial leads make it suitable for constrained PCB layouts while retaining through-hole mechanical stability.
• Frequency-aware ripple performance: Specified ripple currents at 120 Hz and 10 kHz, plus series frequency coefficients for 47 µF, help predict performance across switching and line frequencies.
• Defined endurance: 2000 hours at 85 °C provides a measurable reliability target for thermal endurance planning and lifecycle estimates.
• Predictable leakage behavior: Datasheet leakage current limits expressed as 0.03CV and 0.01CV at test intervals assist in system-level leakage budgeting.
