RR71C271MDN1

The Nichicon RR71C271MDN1 is a 270 µF, 16 V conductive-polymer aluminum solid electrolytic capacitor in a radial-lead can. Engineered for general-purpose power applications, it combines ultra-low ESR and high ripple-current capability to support aggressive filtering and decoupling requirements in compact board-level designs.

Packaged in a φ10 × 12.5 mm can with 5 mm lead spacing and RoHS compliance, this mass-production part is optimized for reliability with a 2000-hour endurance rating at 105°C and a wide operating temperature range from −55°C to 105°C.

Key Features

• Ultra-low ESR — ESR of 7 mΩ measured at 20°C / 100 kHz, reducing conduction losses and enabling better AC performance in high-frequency environments.
• High ripple-current capability — Rated ripple currents of 610 mA at 120 Hz and 6.1 A at 300 kHz support both low- and high-frequency ripple handling.
• Conductive polymer chemistry — Solid polymer construction yields stable electrical characteristics and reduced impedance compared with traditional electrolytic chemistries.
• Wide temperature range and endurance — Specified for −55°C to 105°C operation with a rated life of 2000 hours at 105°C.
• Compact radial package — φ10 × 12.5 mm can with 5 mm lead spacing (±0.5 mm) and radial leads for through-hole mounting and straightforward PCB layout.
• Electrical tolerances and leakage — 270 µF capacitance with −20% to +20% tolerance, tanδ 0.08 (20°C, 120 Hz), and leakage current of 648 µA (measured per datasheet conditions).
• Regulatory and handling — RoHS compliant; available in bulk (no terminal forming) or bag packing for flexible assembly workflows.

Typical Applications

• Power supply filtering — Low ESR and high ripple-current rating make this capacitor suitable for bulk and output filtering in low-voltage power rails.
• DC–DC converter support — The 16 V rating and high-frequency ripple capability address decoupling and smoothing needs near switching stages.
• General-purpose electronics — Designed for a wide range of board-level designs that require compact, reliable aluminum-polymer bulk capacitance across −55°C to 105°C.

Unique Advantages

• Reduced power loss: 7 mΩ ESR at 100 kHz minimizes I²R losses, improving efficiency in high-current AC conditions.
• High ripple endurance: 6.1 A ripple capability at high frequency supports demanding switching and transient environments without excessive heating.
• Thermal robustness: Rated for 2000 hours at 105°C and a −55°C start, enabling reliable operation across harsh temperature profiles.
• Compact footprint: φ10 × 12.5 mm can and 5 mm lead spacing deliver substantial capacitance in a small through-hole package for space-constrained designs.
• Practical packaging options: Available in bulk or bag packing to suit prototype runs and production volumes.
• RoHS compliance: Meets RoHS directive requirements for regulatory-driven assemblies.
