RKS1K180MCNAHGGS

The RKS1K180MCNAHGGS from Nichicon is a surface-mount conductive polymer aluminum solid electrolytic capacitor with 18 µF capacitance and an 80 V rated voltage. It combines low equivalent series resistance and high allowable ripple current with a compact φ8 × 7.7 mm SMD can package for general-purpose power applications.

Engineered for durability across a wide temperature range (−55°C to 125°C) and a long rated lifetime (3000 hours at 125°C), this component is suited to designs that demand stable filtering and decoupling performance under elevated temperature and high-frequency ripple conditions.

Key Features

• Capacitance & Voltage — 18 µF nominal capacitance with an 80 V rated voltage and ±20% tolerance at 20°C, 120 Hz.
• Low Loss / Frequency Performance — Tangent of loss angle (tan δ) specified at 0.12 (measured at 20°C, 120 Hz), supporting effective AC performance.
• Low ESR — ESR of 40 mΩ measured at 20°C / 100 kHz, enabling lower dissipation and improved high-frequency behavior.
• High Ripple Capability — Low-frequency ripple current of 110 mA (120 Hz) and high-frequency ripple current of 1.1 A (300 kHz) for demanding ripple environments.
• Leakage and Reliability — Leakage current rated at 100 µA and an endurance specification of 3000 hours at 125°C under rated voltage.
• Robust Temperature Range — Operates from −55°C to +125°C for stability across automotive and industrial ambient variations (note: no AEC rating is claimed).
• SMD Can Package & Taping — Radial can SMD package (φ8 × 7.7 mm) supplied in embossed carrier taping with moisture-proof packing for automated assembly.
• RoHS Compliant — Conforms to RoHS directive requirements.

Typical Applications

• General-purpose power filtering — Use where an 80 V rated SMD capacitor with low ESR (40 mΩ) is required to stabilize rail voltages and reduce ripple.
• High-frequency decoupling — Suited for circuits needing high-frequency ripple handling thanks to 1.1 A ripple current capability at 300 kHz.
• Elevated-temperature assemblies — Applicable in systems operating up to 125°C where long-term endurance (3000 hours at 125°C) is necessary.

Unique Advantages

• Compact high-voltage SMD option: Delivers 18 µF at 80 V in a φ8 × 7.7 mm SMD can to save board space while meeting higher-voltage requirements.
• Improved thermal endurance: Rated for 3000 hours at 125°C, providing predictable lifetimes in high-temperature environments.
• Low ESR for reduced losses: 40 mΩ ESR at 100 kHz minimizes thermal dissipation and improves efficiency in switching applications.
• High-frequency ripple handling: 1.1 A ripple current at 300 kHz supports demanding switching and decoupling scenarios.
• Manufacturing-ready packaging: Embossed carrier taping with moisture-proof packing facilitates automated pick-and-place and protects parts during handling.
• Measured electrical stability: Specified tan δ (0.12 at 20°C, 120 Hz) and defined leakage current behavior enable predictable AC and DC performance.
