RDS1C680MCNAHFGS

The RDS1C680MCNAHFGS is a conductive polymer aluminum solid electrolytic surface-mount capacitor from Nichicon's RDS series. It delivers 68 µF at 16 V with low ESR and high ripple capability in a compact SMD can package.

Designed for applications that require high-capacitance filtering and sustained performance at elevated temperatures, this part offers a 3000-hour load life at 125 °C and compatibility with lead-free reflow (260 °C peak), making it suitable for demanding power electronics assemblies.

Key Features

• Capacitance & Voltage — 68 µF rated capacitance at 16 V, with capacitance tolerance of ±20% (–20%~20%).
• Low ESR & High Ripple Handling — ESR of 23 mΩ measured at 100 kHz, and rated ripple current of 180 mA at 120 Hz and 1.8 A at 300 kHz, supporting high-frequency and high-current filtering.
• High-Temperature Endurance — Rated operating temperature range from –55 °C to 125 °C with a specified load life of 3000 hours at 125 °C.
• Surface-Mount Package — Radial can SMD package (size code HF): φ8 × L6.7 mm (L: 6.7 × D: 8 mm) with recommended land size 8.3 × 8.3 mm, optimized for PCB assembly.
• Assembly Compatibility — Lead-free reflow soldering compatible up to 260 °C peak.
• Polarized Electrolyte — Polar component with standard polarized mounting requirements.
• Environmental Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Power-supply filtering — Bulk and output filtering where low ESR and high ripple current are required to stabilize DC rails and reduce voltage ripple.
• DC–DC converter outputs — Local decoupling for converters requiring compact, high-capacitance SMD capacitors capable of handling high-frequency ripple up to 300 kHz.
• Industrial and embedded electronics — Power conditioning in boards that operate at elevated ambient temperatures, leveraging the 3000-hour life at 125 °C.

Unique Advantages

• High ripple capability: Rated for 1.8 A at 300 kHz and 180 mA at 120 Hz, enabling effective smoothing of high-frequency and high-current power signals.
• Low ESR for efficiency: 23 mΩ ESR at 100 kHz reduces power loss and heat generation in high-current paths.
• Thermal endurance: 3000-hour lifetime at 125 °C supports long-term reliability in high-temperature assemblies.
• SMD can in compact footprint: φ8 × L6.7 mm package and an 8.3 × 8.3 mm recommended land pattern simplify board layout while providing high capacitance density.
• Lead-free reflow compatible: Peak compatibility to 260 °C allows integration into modern Pb-free assembly processes.
• Regulatory compliance: RoHS conformity supports use in regulated product lines.
