RNU1D471MDN1

The RNU1D471MDN1 is a conductive polymer aluminum solid electrolytic capacitor in a radial lead can package, rated 470 µF at 20 V. It combines high capacitance with low equivalent series resistance and high ripple-current capability for general-purpose electronic designs.

Designed for applications that require compact energy storage and effective high-frequency performance, this component offers a wide operating temperature range of −55 °C to 105 °C and a rated endurance of 2000 hours at 105 °C.

Key Features

• Capacitance & Voltage: 470 µF nominal capacitance with a rated voltage of 20 V and tolerance of −20% to +20% (120 Hz, 20 °C).
• Low ESR & High-Frequency Performance: ESR of 12 mΩ measured at 20 °C / 100 kHz and tan δ of 0.12 at 20 °C / 120 Hz enables efficient high-frequency filtering.
• High Ripple Current Capability: Rated ripple current up to 5.4 A at 300 kHz (frequency coefficient data available) and 540 mA at 120 Hz for robust AC performance.
• Thermal Endurance: Load life specified as 2000 hours at 105 °C under rated voltage, supporting sustained operation in elevated-temperature environments.
• Leakage Current: Specified leakage current of 1880 µA (measured at 20 °C after 2 minutes), suitable for general-purpose circuits with known leakage constraints.
• Compact Radial Package: Metal can case φ10 × 12.5 mm with 5 mm lead spacing and radial lead mounting for through-hole board designs; available in bulk (no terminal forming) or bag packing.
• Environmental Compliance: RoHS compliant per provided product information.

Typical Applications

• General-purpose electronics: Use where 470 µF / 20 V capacitance and low ESR (12 mΩ at 100 kHz) are needed for energy storage and decoupling in board-level designs.
• High-frequency power circuits: Suitable for circuits requiring elevated ripple handling—rated up to 5.4 A at 300 kHz—while maintaining low loss (tan δ 0.12 at 120 Hz).
• Temperature-challenged environments: Applicable in designs that operate across −55 °C to 105 °C with a specified 2000-hour endurance at the upper temperature limit.

Unique Advantages

• Low ESR for efficient filtering: 12 mΩ ESR at 100 kHz reduces AC losses and improves high-frequency filtering performance.
• High ripple-current handling: Rated ripple current up to 5.4 A at 300 kHz supports demanding AC conditions and reduces the need for parallel components.
• Wide operating temperature: −55 °C to 105 °C range enables use across a broad set of environmental conditions.
• Compact radial can format: φ10 × 12.5 mm package with 5 mm lead spacing provides a small footprint for through-hole layouts while keeping substantial capacitance.
• Documented endurance: 2000-hour rated life at 105 °C gives a measurable reliability baseline for thermal stress planning.
• RoHS compliant: Meets environmental compliance requirements noted in the product information.
