RR71A471MDN1

The RR71A471MDN1 is a conductive polymer aluminum solid electrolytic capacitor from Nichicon's RR7 series. It is a radial-lead, polar capacitor rated 10 V with 470 µF nominal capacitance and ±20% tolerance, engineered for general-purpose power applications that demand low equivalent series resistance and high ripple-current capability.

Designed for compact assemblies, this φ10 × 12.5 mm can delivers low ESR and elevated ripple handling across a wide temperature range, providing stable smoothing and decoupling performance in power circuits and switching supplies.

Key Features

• Conductive polymer aluminum construction Solid polymer electrolyte for improved ESR performance and stability compared with traditional wet electrolytes.
• Low ESR ESR specified at 7 mΩ (20°C / 100 kHz), enabling reduced loss and improved transient response in high-frequency applications.
• High ripple-current capability Rated ripple current of 610 mA at 120 Hz and 6.1 A at 300 kHz, supporting both low- and high-frequency filtering demands.
• Electrical ratings 470 µF capacitance, rated voltage 10 V, capacitance tolerance −20% to +20%, and tanδ 0.08 (20°C, 120 Hz).
• Compact radial can package Case size φ10 × 12.5 mm with 5.0 mm lead spacing (±0.5 mm), optimized for through-hole, radial-lead mounting in space-constrained designs.
• Wide operating temperature and endurance Rated for −55°C to +105°C with a rated lifetime of 2000 hours at 105°C.
• Leakage and manufacturing Leakage current specified at 470 µA (after 2 minutes at 20°C), available in bulk/bag packing and currently in mass production.
• RoHS compliant Meets RoHS requirements as indicated in the product data.

Typical Applications

• General-purpose power filtering — Bulk smoothing and decoupling on board-level power rails where low ESR improves voltage stability.
• Switching power supplies — Input/output filtering for converters that require high ripple-current handling at high frequencies.
• Compact through-hole assemblies — Radial lead form factor and small φ10 × 12.5 mm can for space-constrained PCB designs.

Unique Advantages

• Reduced conduction losses: 7 mΩ ESR at 100 kHz minimizes I²R losses and heating under high ripple conditions.
• High-frequency capability: 6.1 A ripple rating at 300 kHz supports modern switching topologies and fast transient currents.
• Robust temperature range: −55°C to +105°C operation suits a wide variety of environmental conditions and thermal profiles.
• Compact radial footprint: φ10 × 12.5 mm can with 5.0 mm lead spacing simplifies layout for through-hole power sections.
• Proven endurance: 2000-hour life at 105°C provides predictable aging characteristics for design planning.
• Regulatory compliance: RoHS conformity for use in regulated assemblies.
