RKS1E680MCNAHHGS

The RKS1E680MCNAHHGS is a surface-mount conductive polymer aluminum electrolytic capacitor from Nichicon's RKS series. It provides 68 µF at 25 V in a compact radial can SMD package and is designed for high-frequency performance and elevated-temperature endurance.

With low ESR, high ripple-current capability and a rated operating range of −55°C to 125°C (3000 hours at 125°C endurance), this part targets compact power designs that require reliable decoupling and energy buffering under thermal stress and repetitive ripple loads.

Key Features

• Capacitance & Voltage — 68 µF nominal capacitance, rated at 25 V with tolerance -20%~20%.
• Low Loss & Frequency Performance — tanδ 0.12 measured at 20°C, 120 Hz, indicating low dissipation; ESR 30 mΩ measured at 20°C, 100 kHz for strong high-frequency behavior.
• High Ripple-Current Capability — Rated ripple current of 160 mA at 120 Hz and 1.6 A at 300 kHz to handle both low- and high-frequency ripple stresses.
• Thermal Endurance — Operating temperature range −55°C to 125°C with a specified load life of 3000 hours at 125°C.
• Surface-Mount, Reflow-Compatible Package — Radial can SMD package with dimensions φ8 × 8.7 mm and designed for lead-free reflow soldering per the datasheet profile.
• Leakage & Reliability — Leakage current specified at 100 µA with datasheet-defined endurance and damp-heat test conditions to ensure stable long-term behavior.
• Manufacturing-Friendly Packaging — Supplied in embossed carrier tape with moisture-proof packing for automated SMT assembly and storage.

Typical Applications

• Power supply decoupling — Low ESR and high ripple-current capability make this part suitable for bulk and rail decoupling in compact SMD power supplies.
• Point-of-load energy storage — 68 µF capacitance and strong high-frequency performance provide local energy buffering for DC–DC converters and regulators.
• High-temperature electronics — Rated to 125°C with 3000-hour load life for assemblies and modules that operate in elevated temperature environments.

Unique Advantages

• High ripple tolerance: 1.6 A high-frequency ripple rating reduces thermal accumulation and extends service life under switching conditions.
• Improved power integrity: 30 mΩ ESR at 100 kHz minimizes high-frequency voltage drop and loss, supporting stable regulator and converter performance.
• Validated endurance at elevated temperature: 3000 hours at 125°C demonstrates sustained performance where thermal reliability is required.
• Simplified assembly: Embossed carrier tape and moisture-proof packing streamline automated pick-and-place and reflow processes.
• Solid conductive-polymer construction: Provides low-loss behavior (tanδ 0.12 at 20°C/120 Hz) and stable electrical characteristics under load.
