RL81C471MDNASQ

The RL81C471MDNASQ is a conductive polymer aluminum solid electrolytic capacitor in a low-profile radial-lead package. It delivers 470 µF capacitance at a 16 V rating with a compact φ8×8 mm can and 3.5 mm lead spacing.

Designed for general-purpose electronic circuits that require low ESR and high ripple-current capability, this part combines a wide operating temperature range and long endurance for reliable performance in demanding environments.

Key Features

• Conductive polymer construction — Solid electrolytic polymer chemistry for stable electrical characteristics.
• Capacitance & tolerance — 470 µF with tolerance of -20% to +20% at 120 Hz, 20°C.
• Low ESR — ESR of 16 mΩ measured at 20°C / 100 kHz, supporting low-impedance designs.
• High ripple-current capability — Low-frequency ripple current 400 mA (120 Hz) and high-frequency ripple current 4 A (300 kHz), suitable for high-ripple environments.
• Thermal and endurance rating — Operating range −55°C to +105°C with a rated life/endurance of 5000 hours at 105°C.
• Compact radial package — φ8×8 mm case, lead spacing 3.5 mm (±0.5 mm), radial leads for through-hole assembly and bulk or bag packing options.
• RoHS compliant — Conforms to RoHS requirements.

Typical Applications

• General-purpose electronic circuits — Suitable where a compact, polarized capacitor with low ESR and reliable endurance is required.
• High-ripple power sections — Handles high ripple currents (4 A at 300 kHz / 400 mA at 120 Hz), making it appropriate for circuits experiencing elevated ripple stress.
• Space-constrained assemblies — Low-profile φ8×8 mm can and radial-lead format fit compact board layouts while preserving performance.

Unique Advantages

• Low impedance at high frequency: 16 mΩ ESR at 100 kHz reduces voltage drop and improves transient response in power circuits.
• High ripple tolerance: Rated for 4 A at 300 kHz and 400 mA at 120 Hz to manage thermal and electrical stress from high-frequency switching.
• Wide temperature range and long life: −55°C to +105°C rating with 5000 hours endurance at 105°C supports durable operation in demanding thermal conditions.
• Compact, through-hole form factor: φ8×8 mm radial-can package with 3.5 mm lead spacing provides a small footprint and straightforward assembly for through-hole designs.
• Regulatory compliance: RoHS-compliant construction aligns with environmental requirements for modern electronic products.
