RKS1C680MCNAFEGS

The RKS1C680MCNAFEGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor from Nichicon's RKS series. It provides 68 µF capacitance at a 16 V rating with a polarized SMD can package sized φ6.3 × 5.8 mm.

Designed for general-purpose power electronics, this capacitor delivers low ESR and substantial high-frequency ripple handling across a wide operating temperature range (–55 °C to 125 °C), with an endurance rating of 3000 hours at 125 °C for demanding thermal environments.

Key Features

• Capacitance and Tolerance — 68 µF nominal with a tolerance of −20% to +20% at 120 Hz, 20 °C.
• Rated Voltage — 16 V DC working voltage suitable for many low-voltage power rail applications.
• Low ESR and Loss — ESR of 50 mΩ measured at 20 °C/100 kHz and tanδ of 0.12 (20 °C, 120 Hz), enabling effective high-frequency filtering and decoupling.
• Ripple Current Capability — Low-frequency ripple current of 100 mA (120 Hz) and high-frequency ripple current of 1.0 A (300 kHz) for robust ripple tolerance.
• Reliability & Life — Endurance rated 3000 hours at 125 °C under rated voltage, supporting long-term operation in high-temperature applications.
• Leakage Current — Specified leakage current of 100 µA, aiding predictable bias behavior after voltage application.
• SMD Can Package — Compact radial can SMD package (φ6.3 × 5.8 mm) supplied in embossed carrier taping with moisture-proof packing for automated assembly.
• Manufacturing and Environmental — SMD type compatible with lead-free reflow soldering (peak 260 °C per series guidance) and RoHS compliant.

Typical Applications

• General-purpose power filtering — Bulk decoupling and smoothing on 16 V rails where 68 µF and low ESR improve voltage stability.
• High-frequency power stages — Filtering and decoupling in circuits that require 1.0 A high-frequency ripple capability and low ESR at 100 kHz.
• Industrial and embedded electronics — Power rail filtering in designs that must operate across –55 °C to 125 °C and withstand extended high-temperature operation.

Unique Advantages

• Low ESR for tighter regulation: 50 mΩ ESR at 100 kHz reduces voltage ripple and aids converter stability.
• High-frequency ripple handling: 1.0 A HF ripple rating supports switching regulator and power-stage demands.
• Wide temperature endurance: Rated −55 °C to 125 °C with 3000-hour life at 125 °C for robust performance in hot environments.
• Compact SMD footprint: φ6.3 × 5.8 mm can package minimizes board area while providing 68 µF capacitance.
• predictable leakage behavior: Specified leakage current of 100 µA enables consistent bias design and margining.
• Assembly-ready packaging: Supplied on embossed carrier tape with moisture-proof packing and compatible with lead-free reflow processes.
