RNU1J470MDN1

The RNU1J470MDN1 from Nichicon is a conductive polymer aluminum solid electrolytic capacitor in a radial lead can package. It delivers 47 µF capacitance at a 63 V rating with low ESR and high ripple current capability, designed for general-purpose electronic applications.

Its core value proposition is delivering compact, low-impedance bulk capacitance with 25 mΩ ESR (20°C/100 kHz) and robust thermal endurance, enabling reliable power filtering and decoupling in a variety of equipment across a −55°C to 105°C operating range.

Key Features

• Capacitance & Voltage — 47 µF nominal capacitance with a 63 V rated voltage and ±20% tolerance for stable bulk energy storage.
• Conductive Polymer Solid Electrolyte — Solid polymer construction for lower ESR and improved high-frequency performance compared to many liquid electrolytes.
• Low ESR & High Ripple Current — 25 mΩ ESR at 20°C/100 kHz with rated ripple currents of 260 mA at 120 Hz and 2.6 A at 300 kHz, supporting both low- and high-frequency decoupling.
• Thermal Endurance — Rated for 2000 hours at 105°C, providing predictable lifetime behavior under elevated temperature stress.
• Wide Operating Temperature — Specified operation from −55°C to 105°C for use across broad environmental conditions.
• Radial Lead, Compact Can — φ10 × 12.5 mm can with 5.0 mm lead spacing (±0.5 mm) for through-hole mounting and straightforward PCB placement.
• Leakage Current — Specified leakage current of 592 µA after rated voltage application at 20°C.
• RoHS Compliant & Production Ready — RoHS compliant, supplied in bulk, and in mass production.

Typical Applications

• General-purpose power filtering — Low ESR and high ripple capability make this capacitor suitable for smoothing and decoupling in a wide range of electronic assemblies.
• Power supply bulk capacitance — 47 µF at 63 V provides compact energy storage for mid-voltage rails requiring robust transient handling.
• High-frequency decoupling — Low ESR measured at 100 kHz and rated ripple current up to 2.6 A at 300 kHz supports high-frequency noise suppression and local bypassing.

Unique Advantages

• Low-impedance performance: 25 mΩ ESR at 20°C/100 kHz directly reduces voltage ripple and improves regulation when used near power converters.
• High ripple tolerance: Rated ripple currents of 260 mA (120 Hz) and 2.6 A (300 kHz) enable reliable operation under both low- and high-frequency loading conditions.
• Thermally qualified: 2000 hours endurance at 105°C provides predictable lifetime characteristics for designs exposed to elevated temperatures.
• Compact through-hole form: φ10×12.5 mm radial can with 5 mm lead spacing simplifies replacement of legacy electrolytic designs while delivering polymer performance.
• Production-ready supply: Mass production status and bulk packaging support BOM planning and volume procurement.
