RNU0J471MDN1

The RNU0J471MDN1 is a radial lead conductive polymer aluminum solid electrolytic capacitor providing 470 µF capacitance at a 6.3 V rating. It combines low equivalent series resistance and high ripple-current capacity in a compact φ8 × 11.5 mm can designed for general-purpose electronic applications.

Engineered for reliability across a wide temperature span (−55 °C to 105 °C) and a rated life of 2000 hours at 105 °C, this component addresses designs that require high capacitance density, low loss, and robust high-frequency performance.

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance with ±20% tolerance and a rated voltage of 6.3 V, suitable for circuits specifying this capacitance/voltage combination.
• Low ESR & High-Frequency Performance — ESR of 7 mΩ measured at 20 °C/100 kHz, supporting high-frequency operation and minimizing power loss at switching frequencies.
• High Ripple Current Capability — Rated ripple currents of 570 mA at 120 Hz and 5.7 A at 300 kHz, delivering sustained ripple handling across low and high frequency ranges.
• Loss Tangent — tanδ of 0.08 at 20 °C/120 Hz for predictable dissipation characteristics in AC conditions.
• Leakage Current — Specified leakage current of 592 µA (measured at 20 °C after 2 minutes), useful for budgeting standby and quiescent currents.
• Reliability & Endurance — Rated for 2000 hours of operation at 105 °C under rated voltage, with defined limits for capacitance change, tanδ and ESR after endurance testing.
• Mechanical & Mounting — Radial lead can package (φ8 × 11.5 mm) with 3.5 mm lead spacing (±0.5 mm) for through-hole mounting; packaging available as bulk (no terminal forming) or bag-packed.
• Operating Range & Compliance — Specified operating temperature −55 °C to 105 °C and RoHS compliant.

Typical Applications

• General-purpose electronic circuits — Provides 470 µF capacitance with low ESR for designers specifying general-purpose capacitor performance.
• High-frequency power conditioning — The 7 mΩ ESR at 100 kHz and a 5.7 A ripple rating at 300 kHz support applications where high-frequency ripple handling is required.
• Thermally demanding environments — Rated for operation from −55 °C to 105 °C with a 2000 h endurance at 105 °C, suitable for designs with elevated ambient temperatures.

Unique Advantages

• Low-loss operation: 7 mΩ ESR at 100 kHz combined with tanδ of 0.08 reduces dissipative losses in AC and switched environments.
• High ripple capability across frequencies: Specified ripple ratings at 120 Hz and 300 kHz allow consistent performance from low to high frequency conditions.
• High capacitance in a compact package: 470 µF in a φ8 × 11.5 mm can saves board space while delivering required bulk capacitance.
• Robust thermal endurance: 2000 hours at 105 °C provides a quantifiable reliability metric for thermal stress planning.
• Through-hole convenience: Radial lead format with defined lead spacing simplifies placement and retention in through-hole assemblies.
• RoHS compliant: Meets RoHS requirements for regulated material content.
