RL81C471MDN1

The RL81C471MDN1 is a conductive polymer aluminum solid electrolytic capacitor in a radial-lead, low-profile φ8 package. It delivers 470 µF at 16 V with very low ESR and high ripple-current capability for general-purpose electronic designs.

Designed for applications that require compact, low-impedance energy storage, this Nichicon RL8-series part balances high-frequency performance, thermal endurance, and leaded mounting for ease of integration into through-hole assemblies.

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance with a rated voltage of 16 V and a tolerance of -20% to +20% (120 Hz, 20°C).
• Conductive Polymer Dielectric — Solid electrolyte construction for stable electrical characteristics and low loss (tanδ ≤ 0.12 at 120 Hz, 20°C).
• Low ESR — ESR of 16 mΩ measured at 20°C / 100 kHz, supporting efficient high-frequency performance.
• High Ripple Current — Rated ripple current 400 mA at 120 Hz and 4 A at 300 kHz for effective smoothing and decoupling under dynamic loads.
• Temperature & Endurance — Wide operating range from -55°C to +105°C and a rated life of 2000 hours at 105°C for reliable performance in elevated-temperature environments.
• Radial Lead Package — Compact φ8 × 8 mm can with 3.5 mm lead spacing (±0.5 mm) and radial leads for through-hole mounting and easy PCB placement; available in bulk or bag packing.
• Leakage Current — Specified leakage current of 1504 µA after 2 minutes at rated voltage and 20°C, supporting predictable bias conditions.
• RoHS Compliant — Manufactured in compliance with RoHS requirements.

Typical Applications

• General Purpose Electronics — Suited for general-purpose circuits requiring compact energy storage with low ESR and predictable lifetime.
• High-Frequency Power Circuits — Effective where high-frequency ripple handling (up to 300 kHz) and low impedance are needed.
• Through-Hole Assemblies — Radial-lead format simplifies hand or wave-soldered PCB implementations and prototyping workflows.

Unique Advantages

• Low-impedance performance: 16 mΩ ESR at 100 kHz minimizes voltage drop and heat generation in high-frequency environments.
• High ripple tolerance: 4 A ripple capability at 300 kHz allows robust decoupling for fast switching circuits and power stages.
• Compact, low-profile form: φ8 package provides a small footprint for space-constrained designs while preserving capacitance.
• Wide temperature endurance: Operates from -55°C to 105°C with a 2000-hour rated life at 105°C for predictable long-term reliability.
• Through-hole convenience: Radial-lead construction and standard 3.5 mm lead spacing ease placement in legacy and mixed-technology boards.
• Supply readiness: Mass-production status and standard bulk/bag packaging support volume procurement and assembly planning.
