RNL1E271MDS1

The Nichicon RNL1E271MDS1 is a conductive polymer aluminum solid electrolytic capacitor in a radial-lead can, delivering 270 µF at 25 V. It is part of the RNL series, designed for general-purpose electronic circuits that require high capacitance in a compact, low-ESR package.

Key value comes from its low equivalent series resistance (10 mΩ at 20°C/100 kHz), high ripple-current capability (580 mA at 120 Hz, 5.8 A at 300 kHz), and rated endurance of 2000 hours at 105°C—making it suitable for designs demanding stable filtering and energy storage across a wide temperature range.

Key Features

• Capacitance & Voltage 270 µF nominal capacitance with tolerance ±20% at a rated voltage of 25 V.
• Conductive Polymer Aluminum Solid Electrolyte Solid electrolyte construction from the RNL series for stable performance and reduced leakage compared with liquid electrolytes.
• Low ESR ESR of 10 mΩ measured at 20°C/100 kHz, enabling lower ripple voltage and reduced dissipation in high-frequency circuits.
• High Ripple Current Rated ripple handling of 580 mA at 120 Hz and 5.8 A at 300 kHz, with frequency coefficients specified in the series datasheet for accurate ripple derating.
• Temperature & Endurance Operates from –55°C to +105°C with a load life rated at 2000 hours at 105°C under rated voltage.
• Radial Can Package φ8×16 mm can with 3.5 mm lead spacing (±0.5 mm), supplied in bulk/bag packing for through-hole assembly.
• RoHS Compliant Meets RoHS directive requirements as specified for the series.

Typical Applications

• Power conversion Bulk decoupling and output filtering in power supplies and DC–DC converters where 270 µF and low ESR reduce ripple and improve stability.
• High-frequency switching circuits Designs that require significant high-frequency ripple handling benefit from the 5.8 A rating at 300 kHz tied to the capacitor’s low ESR.
• Embedded and industrial electronics General-purpose energy storage and smoothing across a wide operating temperature range (–55°C to +105°C) and a 2000-hour endurance at elevated temperature.
• Consumer and audio electronics Power-rail stabilization and decoupling where low ESR and solid electrolyte behavior help maintain clean supply rails.

Unique Advantages

• Low-loss operation: 10 mΩ ESR at 100 kHz minimizes heat and voltage drop under AC conditions, improving overall efficiency.
• High ripple capability: Rated ripple currents (580 mA at 120 Hz; 5.8 A at 300 kHz) allow reliable performance in both low- and high-frequency environments.
• Wide temperature endurance: –55°C to +105°C operating range and a 2000-hour life rating at 105°C support designs exposed to elevated ambient temperatures.
• Compact radial can: φ8×16 mm package with 3.5 mm lead spacing saves board area while remaining easy to handle for through-hole assembly.
• Series-level compliance: Part of the Nichicon RNL series with conductive polymer construction and RoHS compliance for regulated product stacks.
