RKS1E680MCNAJLGS

The RKS1E680MCNAJLGS from Nichicon is a surface-mount conductive polymer aluminum solid electrolytic capacitor in the RKS series, offering 68 µF capacitance at a 25 V rating with ±20% tolerance. Engineered for general-purpose SMD power applications, it combines low equivalent series resistance and high allowable ripple current for efficient filtering and decoupling.

Key performance highlights include an ESR of 20 mΩ (measured at 20°C, 100 kHz), high-frequency ripple capability up to 2 A (at 300 kHz), low-frequency ripple handling of 200 mA (at 120 Hz), and an endurance rating of 3000 hours at 125°C. The part ships in embossed carrier tape with moisture-proof packing and is RoHS compliant.

Key Features

• Electrical Performance — 68 µF capacitance at 25 V with tolerance of -20% to +20%; tangent of loss angle (tanδ) 0.12 at 20°C, 120 Hz.
• Low ESR and High-Frequency Behavior — ESR specified at 20 mΩ at 20°C/100 kHz, supporting high-frequency decoupling and reduced power loss.
• High Allowable Ripple Current — 200 mA at 120 Hz (low frequency) and 2 A at 300 kHz (high frequency) for robust ripple handling across frequency ranges.
• Reliability & Endurance — Rated for 3000 hours at 125°C under rated voltage, with specified limits for capacitance change, tanδ and ESR after endurance testing.
• Thermal & Environmental Range — Wide operating temperature range from -55°C to +125°C and RoHS compliance for regulatory alignment.
• Package & Mounting — Surface-mount radial can (φ10 × 12.4 mm length; seated height 1.24 cm), supplied in embossed carrier tape with moisture-proof packing suitable for SMT assembly.
• Leakage & Loss Control — Specified leakage current up to 100 µA and defined loss characteristics to support stable long-term operation.

Typical Applications

• Power Supply Decoupling — Low ESR and high ripple capability make this capacitor suitable for smoothing and decoupling on power rails.
• DC–DC Converter Input/Output Filtering — High allowable ripple current and low loss at high frequency support stable converter performance.
• High-Frequency Power Modules — ESR specified at 100 kHz and ripple performance at 300 kHz align with filtering needs in high-frequency power stages.
• General Purpose Surface-Mount Designs — Robust temperature range and long life at elevated temperature suit demanding embedded and industrial electronics requiring reliable bulk capacitance.

Unique Advantages

• Low ESR for efficient filtering: 20 mΩ ESR at 100 kHz reduces voltage drop and dissipated heat in power circuits.
• Broad ripple handling across frequencies: Rated for 200 mA at 120 Hz and 2 A at 300 kHz, enabling use in both low- and high-frequency filtering tasks.
• Long high-temperature endurance: 3000 hours at 125°C under rated voltage provides predictable lifetime in elevated-temperature environments.
• SMD-friendly packaging and solder tolerance: Surface-mount radial-can format supplied in embossed carrier tape with moisture-proof packing and soldering profile compatibility noted in the series datasheet.
• Stable leakage and loss characteristics: Leakage current specified at 100 µA and tanδ of 0.12 (20°C, 120 Hz) for controlled standby behavior and predictable AC loss.
• Regulatory compliance and production status: RoHS compliant and listed as mass production, supporting volume procurement and environmental requirements.
