RNS1C470MDS1

The RNS1C470MDS1 from Nichicon is a conductive polymer aluminum solid electrolytic capacitor in a radial-lead can designed for general-purpose electronic applications. It combines low ESR and high-frequency ripple capability in a compact φ6.3×10 mm package for power filtering and decoupling on tightly spaced PCBs.

Built for durability in demanding environments, the RNS1C470MDS1 supports a wide operating temperature range and a validated endurance rating that helps maintain capacitance and electrical characteristics over long-term operation.

Key Features

• Capacitance and Tolerance — 47 µF nominal capacitance with tolerance of −20% to +20% (measured at 120 Hz, 20°C), suitable for general-purpose smoothing and decoupling.
• Rated Voltage — 16 V rated working voltage for low-voltage power rail applications.
• Low Loss (tan δ) — tanδ = 0.06 measured at 20°C, 120 Hz, enabling predictable AC loss behavior in filter and decoupling circuits.
• Low ESR — ESR of 42 mΩ at 20°C/100 kHz, supporting efficient high-frequency performance and reduced heat generation.
• High Ripple Current Capability — 240 mA at 120 Hz (low frequency) and 2.4 A at 300 kHz (high frequency), enabling effective handling of both low- and high-frequency ripple on power rails.
• Leakage Current — Specified leakage current of 112 µA after 2 minutes at rated voltage and 25°C, useful for power-budget calculations in standby and low-current systems.
• Endurance — Life rating of 2000 hours at 105°C and rated voltage, with limits on capacitance change, tanδ, ESR, and leakage current per datasheet endurance test.
• Wide Temperature Range — Operates from −55°C to +105°C, suitable for a broad set of ambient conditions.
• Compact Radial Package — φ6.3×10 mm can with 2.5 mm lead spacing (±0.5 mm), delivered in bulk or bag packing and mass-production status for volume designs.

Typical Applications

• Power Supply Filtering — Smoothing and ripple suppression on low-voltage DC rails where compact, low-ESR capacitors are required.
• Decoupling for High-Frequency Circuits — Local decoupling for switching regulators and converters that produce high-frequency ripple up to 300 kHz.
• Embedded and General-Purpose Electronics — Bulk and board-level energy storage in consumer and industrial electronics where general-purpose reliability and long endurance are needed.

Unique Advantages

• Low ESR for Efficient Filtering: 42 mΩ ESR at 100 kHz reduces power loss and improves filtering effectiveness at high frequencies.
• High-Frequency Ripple Handling: Rated for 2.4 A ripple at 300 kHz, enabling use directly on fast switching power stages.
• Thermal and Operational Robustness: −55°C to +105°C operating range and 2000 h endurance at 105°C provide predictable performance in elevated-temperature environments.
• Predictable AC Loss: tanδ = 0.06 at 120 Hz, 20°C helps designers estimate dissipation and stability in AC conditions.
• Compact Radial Form Factor: φ6.3×10 mm can and 2.5 mm lead spacing deliver a small footprint for dense PCB layouts while retaining through-hole mounting simplicity.
• Production-Ready Packaging: Available in bulk or bag packing and listed as mass production, supporting prototyping through volume builds.
