RS81C271MDNASQ

The RS81C271MDNASQ is a conductive polymer aluminum solid electrolytic capacitor in a low-profile radial lead can. It provides 270 µF capacitance at a 16 V rating with low ESR/ESL construction and is intended for general-purpose power applications.

Designed for compact assemblies, the device combines low ESR (15 mΩ at 20°C/100 kHz), high ripple capability (380 mA at 120 Hz and 3.8 A at 300 kHz), and a wide operating temperature range of -55°C to 105°C with a 5000-hour endurance at 105°C.

Key Features

• Capacitance and Voltage — 270 µF rated capacitance at 16 V for energy storage and smoothing in power circuits.
• Low ESR / High Ripple Capacity — 15 mΩ ESR (20°C/100 kHz) and up to 3.8 A ripple current at 300 kHz support high-frequency decoupling and switching regulator outputs.
• Wide Temperature & Endurance — Operating range −55°C to 105°C and 5000 hours life at 105°C for long-term thermal performance.
• Radial Lead Package — φ6.3 × 8 mm can with 2.5 mm lead spacing (±0.5 mm) for through-hole PCB mounting; supplied bulk/no terminal forming.
• Leakage Current Specified — Designed leakage current of 1296 µA after standard conditioning, measurable after rated voltage application per test conditions.
• RoHS Compliant — Meets RoHS environmental restrictions.

Typical Applications

• General-purpose power circuits — Bulk decoupling and smoothing where low ESR and compact radial package are required.
• Switching regulator outputs — High ripple current capability at high frequency supports filtering on DC–DC converters and power modules.
• Compact industrial electronics — Low-profile φ6.3×8 mm can fits space-constrained designs while providing long endurance at elevated temperature.

Unique Advantages

• Low-profile radial form factor: φ6.3×8 mm size and 2.5 mm lead spacing enable tight PCB layouts without sacrificing capacitance.
• High-frequency performance: 15 mΩ ESR at 100 kHz and 3.8 A ripple at 300 kHz allow effective suppression of switching noise and ripple at higher frequencies.
• Thermal endurance: 5000 hours rated life at 105°C supports reliable operation in elevated-temperature environments.
• Conductive polymer chemistry: Solid electrolyte construction provides inherently low ESR/ESL characteristics for improved transient response.
• Production-ready packaging: Supplied in bulk with no terminal forming, suitable for volume through-hole assembly processes.
