RKS1D680MCNAJJGS

The RKS1D680MCNAJJGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor from Nichicon's RKS series. It provides 68 µF capacitance at a 20 V rating in a compact φ10 × 10 mm SMD can.

Designed for general-purpose electronic designs, this part combines low ESR and high allowable ripple current with a wide operating temperature range and a 3000‑hour life rating at 125 °C to support reliable power decoupling and filtering in surface-mount assemblies.

Key Features

• Capacitance & Voltage — 68 µF nominal capacitance with a 20 V rated voltage and ±20% tolerance.
• Conductive Polymer Electrolyte — Solid conductive polymer aluminum construction for stable performance and reduced loss.
• Low Loss (tan δ) — tanδ of 0.12 measured at 20 °C, 120 Hz for predictable AC performance.
• Low ESR — ESR of 20 mΩ at 20 °C, 100 kHz, enabling efficient high-frequency operation.
• High Ripple Capability — Low-frequency ripple current 200 mA at 120 Hz and high-frequency ripple current 2.0 A at 300 kHz to support noisy power rails.
• Leakage Current — Specified leakage current up to 100 µA.
• Long Life — Rated endurance of 3000 hours at 125 °C under rated voltage conditions.
• Wide Temperature Range — Operates from −55 °C to +125 °C.
• SMD Can Package & Assembly Friendly — φ10 × 10L can-style SMD with embossed carrier taping and moisture‑proof packing for automated placement; compatible with lead‑free reflow up to a 260 °C peak per datasheet reflow conditions.
• Compliance — RoHS‑compliant.

Typical Applications

• General-purpose SMD designs — Surface‑mount assemblies that require 68 µF bulk capacitance in a compact can-style package.
• Power filtering on PCBs — Use where low ESR and specified ripple currents support stable supply rails in general-purpose circuits.
• Surface-mount module integration — Suitable for modules and board-level designs that need automated placement and moisture‑proof packaging.

Unique Advantages

• Low ESR performance: 20 mΩ at 100 kHz reduces loss and supports higher-frequency ripple currents for cleaner rails.
• High ripple tolerance: 2.0 A high-frequency ripple rating enables use on demanding switching supplies and high-frequency circuits.
• Extended high-temperature life: 3000 hours at 125 °C provides predictable endurance for designs exposed to elevated operating temperatures.
• Compact SMD can: φ10 × 10 mm package delivers high capacitance in a small footprint suitable for space-constrained board layouts.
• Assembly-ready packaging: Embossed carrier taping with moisture‑proof packing facilitates automated pick-and-place and reflow processes.
• Regulatory readiness: RoHS compliance supports use in environments requiring restricted substance conformity.
