RKS1E680MCNAFEGS

The RKS1E680MCNAFEGS is a surface-mount conductive-polymer aluminum electrolytic capacitor engineered for compact board-level power applications. With a rated capacitance of 68 µF at 25 V and a small φ6.3 × 5.8 mm can, it delivers low ESR and high allowable ripple current in a reflow-compatible SMD package.

Designed for robust operation from −55 °C to 125 °C and a rated life of 3000 hours at 125 °C, this part is targeted at designs that require stable capacitance, low loss, and extended high-temperature endurance.

Key Features

• Capacitance & Voltage — 68 µF nominal capacitance at a rated voltage of 25 V, with capacitance tolerance of −20% to +20% (measured at 20 °C, 120 Hz).
• Conductive-Polymer Construction — Solid conductive-polymer aluminum electrolytic architecture for low loss and stable performance under load.
• Low Loss / Low ESR — Tangent of loss angle (tan δ) of 0.12 (20 °C, 120 Hz) and ESR of 50 mΩ measured at 20 °C/100 kHz, supporting efficient high-frequency performance.
• High Ripple Capability — Rated ripple currents of 90 mA at 120 Hz (low frequency) and 900 mA at 300 kHz (high frequency) for demanding ripple environments.
• Leakage Current — Specified leakage current of 100 µA, measured after 2 minutes at rated voltage.
• Extended High-Temperature Life — Load life specified at 3000 hours at 125 °C, with defined limits for capacitance change, tan δ, ESR and leakage after endurance testing.
• SMD Package & Reflow Compatible — Surface-mount radial can (φ6.3 × 5.8 mm) supplied in embossed carrier taping with moisture-proof packing; compatible with lead-free reflow peak temperatures up to 260 °C per the series soldering specification.
• Wide Operating Temperature — Rated for −55 °C to +125 °C operation.
• RoHS Compliant — Meets RoHS directive requirements as specified in the product datasheet.

Typical Applications

• Board-level power decoupling — Use where compact SMD capacitance and low ESR are required to stabilize local power rails at up to 25 V.
• High-frequency power circuits — Suitable for circuits that demand high allowable ripple current and low loss at high switching frequencies.
• High-temperature electronics — Appropriate for assemblies that require sustained operation and proven endurance at elevated temperatures up to 125 °C.

Unique Advantages

• High ripple tolerance: 900 mA at 300 kHz high-frequency ripple rating supports aggressive switching and power conversion topologies.
• Low ESR and low loss: 50 mΩ ESR and tan δ of 0.12 reduce dissipation and improve efficiency in high-frequency applications.
• Compact SMD can: φ6.3 × 5.8 mm body with recommended land size 6.6 × 6.6 mm enables dense PCB layouts while retaining sizable capacitance.
• Extended 125 °C life: 3000-hour rated life at 125 °C provides predictable endurance for long-term, high-temperature operation.
• Manufacturing-friendly packaging: Embossed carrier tape and moisture-proof packing simplify automated placement and handling for volume production.
• Reflow compatibility: Specified resistance to soldering heat up to 260 °C peak for lead-free assembly processes.
