PLS1A271MDO1

The PLS1A271MDO1 is a conductive polymer aluminum solid electrolytic capacitor in a radial lead can, optimized for long-life, high-ripple applications in general-purpose electronics. It combines ultra-low ESR and high ripple-current capability with a robust temperature range and lead-free flow soldering compatibility.

Key value propositions include low impedance at high frequency, extended load life at elevated temperature, and a radial-lead package suited for through-hole mounting in power and filtering circuits.

Key Features

• Capacitance and Voltage: 270 µF rated at 10 V for bulk energy storage and decoupling in low-voltage designs.
• Ultra-low ESR: 8 mΩ ESR measured at 100 kHz, minimizing losses and improving power-conversion efficiency.
• High Ripple Current: Supports 4.9 A at 100 kHz and 2.45 A at 120 Hz, enabling reliable performance under high AC stress.
• Long Life at Elevated Temperature: Specified for 5000 hours at 105°C to support prolonged operation in thermally demanding environments.
• Wide Operating Temperature: −55°C to +105°C rating for stable behavior across common industrial and commercial temperature ranges.
• Radial Lead, Through-hole Package: Radial can with 3.5 mm lead spacing for straightforward through-hole assembly and mechanical robustness.
• Polarized, General-Purpose Design: Polar capacitor with ±20% tolerance, intended for general-purpose power and filtering applications.
• Lead-free Soldering Compatibility & RoHS Compliance: Compatible with lead-free flow soldering conditions and compliant with RoHS (2011/65/EU, (EU)2015/863).

Typical Applications

• Power Supply Filtering: Ultra-low ESR and high ripple-current capability make it suitable for smoothing and decoupling in switching and linear power supplies.
• Buck/Boost Converters: Designed to handle high ripple currents and reduce voltage ripple in DC–DC converter output stages.
• General-Purpose Electronics: Through-hole radial package and robust temperature/life specifications suit a wide range of consumer and industrial control boards.

Unique Advantages

• Reduced Heat and Losses: Low ESR (8 mΩ at 100 kHz) lowers I²R losses, improving efficiency in power-dense circuits.
• Reliable High-AC Performance: High ripple-current ratings (4.9 A at 100 kHz) help maintain capacitor stability under continuous AC loading.
• Extended High-Temperature Endurance: 5000-hour load life at 105°C supports longer maintenance intervals and predictable long-term behavior.
• Through-Hole Robustness: Radial lead can and 3.5 mm lead spacing provide mechanical durability for wave/flow soldered assemblies.
• Regulatory Compliance: RoHS-compliant construction and lead-free flow soldering compatibility support modern assembly and environmental requirements.
