RL81C271MCN1

The RL81C271MCN1 from Nichicon is a conductive polymer aluminum solid electrolytic capacitor in the RL8 series designed for general-purpose power applications that require ultra low ESR and high ripple-current capability. Its compact radial-can φ8 package and conductive-polymer construction deliver high-frequency performance and reliability across a wide temperature range.

Engineered for demanding board-level power decoupling and smoothing tasks, this component combines 270 µF capacitance at 16 V with low ESR, substantial ripple handling, and RoHS compliance to support robust, lead-free manufacturing flows.

Key Features

• Capacitance & Voltage — 270 µF rated capacitance at 16 V with ±20% tolerance, suitable for bulk decoupling and energy storage in low-voltage systems.
• Ultra Low ESR — 10 mΩ equivalent series resistance measured at 100 kHz (20°C), reducing I·R losses and improving high-frequency response.
• High Ripple Current — Rated ripple current up to 5 A at 300 kHz and 500 mA at 120 Hz, enabling effective handling of switching-current transients and high-frequency noise.
• Thermal & Endurance Performance — Operating temperature range from −55°C to +105°C with load-life options of 2000 hours (series options up to 5000 hours at 105°C), providing sustained performance under elevated-temperature stress.
• Package & Mounting — Radial lead, can-style package (φD×L = 8×8 mm) with 3.5 mm lead spacing, compatible with leaded assembly and lead-free flow soldering conditions.
• Environmental Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Power Supply Decoupling — Low ESR and high ripple-current rating make this capacitor suitable for smoothing and decoupling in DC–DC converters and regulator outputs.
• Switching Power Modules — Compact φ8 can and high-frequency performance support use near switching stages to absorb switching transients and reduce voltage ripple.
• Embedded Systems — General-purpose energy storage and decoupling in compact, low-voltage embedded designs requiring robust thermal endurance.

Unique Advantages

• Low-loss polymer electrolyte — Ultra low ESR (10 mΩ at 100 kHz) directly improves efficiency by minimizing conduction losses in high-frequency circuits.
• High ripple resilience — 5 A ripple capability at 300 kHz supports high-current switching environments and reduces capacitor count for the same ripple-handling requirement.
• Compact radial package — φ8×8 mm can with 3.5 mm lead spacing offers a small footprint for space-constrained boards while retaining substantial capacitance.
• Thermal endurance options — Specified load-life of 2000 hours at 105°C (series options up to 5000 hours) enables predictable long-term behavior under elevated operating temperatures.
• Lead-free assembly ready — Designed to meet lead-free flow soldering condition correspondence for modern manufacturing processes.
• Regulatory compliance — RoHS-compliant materials support environmentally conscious designs and meet common regulatory requirements.
