RKS1K120MCNAHFGS

The RKS1K120MCNAHFGS from Nichicon is a surface-mount conductive polymer aluminum solid electrolytic capacitor specified at 12 µF and 80 V. Designed for general-purpose power filtering and decoupling, it delivers low ESR and substantial high-frequency ripple current capability in a compact radial can SMD package (φ8 × 6.7 mm).

This part targets applications that require robust high-voltage SMD capacitance with extended endurance up to 3000 hours at 125°C, RoHS compliance, and packaging suitable for automated assembly (embossed carrier taping / moisture proof packing).

Key Features

• Capacitance & Voltage — 12 µF rated capacitance with an 80 V rated voltage and capacitance tolerance of ±20% (–20% ~ 20%).
• Conductive Polymer Electrolyte — Solid conductive polymer construction suited for surface-mount implementations and stable performance across the specified temperature range.
• Low ESR & High-Frequency Performance — ESR of 40 mΩ measured at 100 kHz (20°C) and high-frequency ripple current rating of 1.1 A at 300 kHz, enabling effective decoupling in switching circuits.
• Ripple Current Capability — Low-frequency ripple current of 110 mA at 120 Hz and high-frequency ripple handling of 1.1 A at 300 kHz for mixed-frequency power environments.
• Leakage & Reliability — Leakage current specified at 100 µA (measured per datasheet conditions) and load life endurance of 3000 hours at 125°C.
• Temperature Range & Durability — Rated for operation from –55°C to +125°C with endurance and shelf-life characteristics defined in the datasheet.
• SMD Package & Assembly — Radial can SMD package (φ8 × 6.7 mm) supplied in embossed carrier taping with moisture-proof packing; compatible with lead-free reflow soldering profiles per the product documentation.
• Environmental Compliance — RoHS compliant.

Typical Applications

• Switching Power Supplies — High-frequency ripple current rating and low ESR make this capacitor suitable for output filtering and decoupling in DC–DC converters and regulators.
• Power Management Modules — Compact SMD form factor and 80 V rating allow use in power modules where space and voltage margin are critical.
• Industrial Electronics — Extended 3000-hour endurance at 125°C supports long-term operation in industrial power and control equipment subject to elevated temperatures.
• Telecom and Infrastructure — Low ESR and measurable high-frequency performance benefit filtering stages in communications power systems and infrastructure electronics.

Unique Advantages

• High ripple tolerance: 1.1 A at 300 kHz and 110 mA at 120 Hz enable reliable handling of both switching- and line-frequency ripple.
• Low ESR for HF decoupling: 40 mΩ (100 kHz) reduces voltage drop and heat generation in high-frequency circuits.
• Extended high-temperature endurance: Rated life of 3000 hours at 125°C supports long-term deployments in thermally stressed environments.
• Compact SMD radial can: φ8 × 6.7 mm package provides a space-efficient option for boards requiring axial can-like capacitance in an SMD footprint.
• Manufacturing-ready packaging: Supplied in embossed carrier taping with moisture-proof packing to support automated pick-and-place and reflow processes.
• Regulatory compliance: RoHS conformity simplifies integration into designs targeting restricted-substance requirements.
