RL81C271MDNASQ

The RL81C271MDNASQ is a conductive polymer aluminum solid electrolytic capacitor designed for low ESR and high ripple-current applications in compact, radial-leaded packages. It delivers 270 µF at 16 V in a low-profile φ8×8 mm can with a radial lead footprint.

Engineered for general-purpose electronic designs, this part combines ultra-low ESR performance with a wide operating temperature range and long high-temperature load life, providing a reliable choice where high AC current handling and compact size are required.

Key Features

• Capacitance & Voltage — 270 µF rated capacitance at 16 V with tolerance of −20% to +20%.
• Conductive Polymer Electrolyte — Solid electrolyte construction offering ultra-low ESR and high ripple capability for improved dynamic performance.
• Ultra-Low ESR — ESR of 10 mΩ measured at 100 kHz (20°C), reducing impedance in high-frequency circuits.
• High Ripple Current — Rated ripple current up to 5 A at 300 kHz and 500 mA at 120 Hz, with frequency coefficients defined across 120 Hz–300 kHz (0.10 at 120 Hz; 0.45 at 1 kHz; 0.50 at 10 kHz; 1.00 at 100 kHz and 300 kHz).
• Compact, Low-Profile Package — φ8×8 mm can with 3.5 mm lead spacing and radial lead mounting for through-hole assembly.
• Wide Temperature & Long Life — Operating range −55°C to +105°C and a load life of 5000 hours at 105°C.
• Assembly and Compliance — Radial lead type compatible with lead-free flow soldering conditions and RoHS compliant.

Typical Applications

• Power Conversion — Use on DC–DC converter outputs and regulator stages where the 5 A ripple capability at 300 kHz and 10 mΩ ESR help control output ripple and thermal rise.
• Point-of-Load Filtering — Compact φ8×8 size and low ESR make it suitable for decoupling and bulk storage in space-constrained point-of-load circuits.
• High-Frequency Power Stages — Frequency coefficient information and 100 kHz/300 kHz ratings support use in high-frequency switching environments.

Unique Advantages

• Lower circuit impedance: 10 mΩ ESR at 100 kHz minimizes voltage drop under high-frequency load transients.
• Improved thermal headroom: High ripple-current ratings (up to 5 A at 300 kHz) reduce heating in high-AC-current designs.
• Space-efficient form factor: φ8×8 mm can with 3.5 mm lead spacing and low profile supports compact through-hole layouts.
• Durable at elevated temperature: Rated for −55°C to +105°C with a 5000-hour load life at 105°C for extended high-temperature operation.
• Assembly-ready and compliant: Radial lead, lead-free flow soldering correspondence and RoHS compliance simplify production and regulatory alignment.
