RKS1E820MCNAFGGS

The RKS1E820MCNAFGGS is a surface-mount conductive polymer aluminum electrolytic capacitor featuring 82 µF capacitance at 25 V. Engineered for compact power applications, it delivers low ESR and high allowable ripple current in a space-efficient radial can SMD package (φ6.3 × 7.7 mm).

Designed for demanding thermal and frequency environments, this component supports operation from −55°C to 125°C and offers a rated load life of 3000 hours at 125°C, making it suitable where high ripple performance, stability, and long endurance are required.

Key Features

• Core Type — Conductive Polymer Aluminum Solid Electrolyte Provides stable, solid electrolyte performance for improved high-frequency behavior and reduced loss compared with liquid electrolytes.
• Electrical Performance 82 µF nominal capacitance at 25 V with tolerance −20% to +20%, tangent of loss angle (tanδ) 0.12 (measured at 20°C, 120 Hz), and leakage current specified at 102 µA.
• Low ESR and High Ripple Handling ESR of 30 mΩ measured at 20°C/100 kHz, low-frequency ripple current 140 mA (120 Hz), and high-frequency ripple current 1.4 A (300 kHz) to support switching and high-frequency decoupling needs.
• High-Temperature Endurance Rated for −55°C to +125°C with a load life of 3000 hours at 125°C, providing long-term stability under elevated temperature stress.
• SMD Radial Can Package Compact φ6.3 × 7.7 mm package (seated land size 6.6 × 6.6 mm) optimized for board-level density and automated assembly.
• Assembly and Handling Compatible with lead-free reflow soldering (peak 260°C per series soldering profile) and supplied in embossed carrier taping with moisture-proof packing for production SMT lines.
• Regulatory Compliance RoHS compliant.

Typical Applications

• Switching regulator output smoothing — Low ESR (30 mΩ @100 kHz) and 1.4 A high-frequency ripple capability make this capacitor suitable for smoothing outputs of DC–DC converters and switching regulators.
• Power rail decoupling — 82 µF capacitance combined with low loss (tanδ 0.12) supports stable decoupling on intermediate and local power rails in compact designs.
• High-frequency power modules — Compact radial SMD package and high ripple current rating help manage thermal and electrical stress in dense power modules and power management assemblies.

Unique Advantages

• High ripple tolerance: 1.4 A at 300 kHz and 140 mA at 120 Hz reduce voltage ripple and improve regulator stability in high-frequency circuits.
• Low ESR for improved efficiency: 30 mΩ ESR at 100 kHz minimizes I2R losses and enables tighter voltage regulation in compact power systems.
• Extended high-temperature life: 3000 hours at 125°C provides predictable long-term performance in elevated-temperature operating environments.
• SMT-compatible packaging: φ6.3 × 7.7 mm radial can in embossed carrier taping with moisture-proof packing supports automated assembly and handling.
• Solid electrolyte reliability: Conductive polymer chemistry delivers stable electrical characteristics and low loss across frequency and temperature ranges.
• Regulatory readiness: RoHS compliance supports use in products requiring restricted-substance conformity.
