RNU0E272MDN1

The RNU0E272MDN1 is a conductive polymer aluminum solid electrolytic capacitor in a radial-lead can, part of Nichicon’s RNU series. It delivers 2700 µF capacitance at a low rated voltage of 2.5 V with a compact φ10×12.5 mm case and a radial mounting footprint.

Designed for general-purpose low‑voltage, high‑capacitance applications, this device combines low ESR and high ripple capability with a wide operating temperature range and a 2000‑hour endurance rating at 105 °C to support reliable power‑rail decoupling and energy storage in compact through‑hole designs.

Key Features

• Capacitance & Voltage  2700 µF (2.7 mF) nominal capacitance with a 2.5 V rated voltage and ±20% tolerance for high bulk energy storage in low‑voltage circuits.
• Conductive Polymer Construction  Solid polymer electrolyte technology for stable performance and reduced ESR compared to traditional electrolytics.
• Low ESR  7 mΩ ESR measured at 20 °C / 100 kHz, enabling improved transient response and lower power loss.
• High Ripple Current Capability  Rated ripple current of 610 mA at 120 Hz and 6.1 A at 300 kHz supports high AC stress in power‑supply applications.
• Leakage Current  1350 µA maximum leakage after 2 minutes at 20 °C, consistent with solid polymer capacitor behavior.
• Temperature & Endurance  Wide operating range from −55 °C to +105 °C and a rated life of 2000 hours at 105 °C.
• Radial Through‑Hole Package  φ10×12.5 mm can with 5.0 mm lead spacing (±0.5 mm) and radial leads for straightforward through‑hole assembly.
• Packing & Production  Available in bulk/no terminal forming and bag packing; product is in mass production and RoHS compliant.

Typical Applications

• General‑purpose electronics  Provides bulk energy storage and decoupling for low‑voltage circuit blocks where high capacitance and low ESR are required.
• Power‑rail stabilization  Used on low‑voltage rails to smooth transients and support fast load changes thanks to low ESR and high ripple current capability.
• Embedded and industrial modules  Compact radial can package and wide temperature range support rugged through‑hole module designs operating up to 105 °C.

Unique Advantages

• High capacitance in a compact can: 2700 µF in a φ10×12.5 mm case provides large charge storage while minimizing board footprint.
• Low ESR for efficient power handling: 7 mΩ at 100 kHz reduces resistive losses and improves converter/transient performance.
• Broad ripple capability: Rated ripple current from 610 mA (120 Hz) up to 6.1 A (300 kHz) supports a range of low‑frequency and high‑frequency power conditions.
• Thermal and lifecycle robustness: −55 °C to +105 °C operating range with 2000 hours endurance at 105 °C for sustained performance in heated environments.
• Through‑hole convenience: Radial lead configuration with 5.0 mm lead spacing (±0.5 mm) simplifies placement and soldering in traditional assembly flows.
• Production‑ready packaging: Bulk and bag packing options support high‑volume manufacturing and handling needs; RoHS compliant for regulatory alignment.
