RL81C271MCNASQ

The RL81C271MCNASQ is a conductive polymer aluminum solid electrolytic capacitor from Nichicon's RL8 series. It delivers ultra-low ESR and high ripple-current capability in a compact, low-profile radial can (φ8×8 mm) package.

Designed for general-purpose electronic applications, this polarized radial-lead capacitor combines low impedance, a wide operating temperature range (−55°C to 105°C), and a 5000-hour endurance at 105°C to support demanding power-filtering and high-frequency ripple environments.

Key Features

• Capacitance and Voltage: 270 µF capacitance with a rated voltage of 16 V and a tolerance of ±20% (120 Hz, 20°C).
• Ultra-Low ESR: ESR of 10 mΩ measured at 20°C/100 kHz for reduced impedance and improved transient performance.
• High Ripple-Current Capability: Low-frequency ripple current of 500 mA (120 Hz) and high-frequency ripple current of 5 A (300 kHz) to handle both bulk and high-speed switching ripple.
• Low Profile, Radial Can Package: Compact φ8×8 mm case with radial leads and 3.5 mm lead spacing (±0.5 mm) for through-hole layouts where board height and space are constrained.
• Extended Temperature and Endurance: Operating temperature range −55°C to 105°C with a rated life of 5000 hours at 105°C.
• Electrical Loss and Leakage: Tangent of loss angle (tan δ) of 0.12 and specified leakage current (description) of 864 µA after standard conditioning.
• Assembly Compatibility: Radial lead type noted as corresponding to lead-free flow soldering conditions.
• Environmental Compliance: Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Power Supply Filtering: Low ESR and high ripple-current capability make this part suitable for bulk and decoupling roles in compact power supplies.
• High-Frequency DC–DC Converters: Supports high-frequency ripple currents (5 A at 300 kHz) to stabilize switching regulator outputs.
• General-Purpose Electronic Circuits: Polarized radial-lead form and compact footprint fit a broad range of general-purpose PCB applications requiring robust capacitance in limited height.

Unique Advantages

• Low impedance at high frequency: 10 mΩ ESR at 100 kHz reduces voltage ripple and improves dynamic response in high-speed circuits.
• High ripple handling in a small package: 5 A high-frequency ripple current capability in a φ8×8 mm can enables compact designs without sacrificing ripple performance.
• Durable thermal performance: Rated for −55°C to 105°C and 5000 hours at 105°C, providing stability for extended operation under elevated temperatures.
• Space-efficient, through-hole form factor: Radial, can-style package with 3.5 mm lead spacing simplifies placement in constrained board layouts while supporting conventional assembly.
• RoHS compliant: Meets current RoHS requirements for material and environmental conformity.
