RL81C471MCN1

The RL81C471MCN1 is a conductive polymer aluminum solid electrolytic capacitor in Nichicon's RL8 series designed for general-purpose power applications. It delivers ultra low ESR and high ripple current capability in a compact radial-can, low-profile φ8 package.

Targeted at systems requiring robust high-frequency performance and thermal endurance, this part supports demanding ripple environments while maintaining a small footprint and RoHS compliance.

Key Features

• Core Technology — Conductive Polymer: Solid polymer electrolyte construction provides ultra low ESR for improved high-frequency performance and stable electrical characteristics.
• Electrical Performance: 470 µF capacitance at 16 V rated voltage with ±20% tolerance; ESR specified at 16 mΩ (100 kHz, 20°C).
• High Ripple Capability: Rated ripple current of 400 mA at 120 Hz and 4 A at 300 kHz, with frequency coefficients defined up to 300 kHz for accurate ripple-current planning.
• Package & Mounting: φ8 radial can with radial lead mounting and 3.5 mm lead spacing; compact size specified as L: 8 × D: 8 mm.
• Thermal and Lifetime Ratings: Operating temperature range −55°C to +105°C with a specified load life of 2000 hours at 105°C.
• Regulatory Compliance: Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Power Supplies: Bulk smoothing and output filtering where low ESR and high ripple current handling reduce voltage ripple and thermal stress.
• DC–DC Converters: Input and output decoupling in switched-mode power supplies that operate at high switching frequencies, leveraging the capacitor's 100 kHz / 300 kHz performance.
• Industrial and Embedded Systems: General-purpose energy storage and decoupling across temperature extremes (−55°C to +105°C) and extended high-temperature operation.
• Networking and Communications Equipment: High-frequency decoupling and ripple management for modules that demand low ESR in a compact radial-can package.

Unique Advantages

• Ultra Low ESR: 16 mΩ at 100 kHz reduces losses and improves transient response for high-frequency decoupling.
• High-Frequency Ripple Handling: 4 A ripple rating at 300 kHz (and defined coefficients across frequencies) supports modern switching regulator topologies.
• Compact, Low-Profile Packaging: φ8 radial-can construction with 3.5 mm lead spacing and 8 × 8 mm dimensions conserves board area while enabling through-hole assembly.
• Wide Temperature Range: −55°C to +105°C operation provides versatility across harsh and varied environmental conditions.
• Durability at Elevated Temperature: Specified load life of 2000 hours at 105°C for predictable end-of-life behavior in high-temperature applications.
• RoHS Compliance: Meets RoHS (2011/65/EU, (EU)2015/863) requirements for environmental and material conformity.
