RKS1C181MCNAJJGS

The RKS1C181MCNAJJGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor in Nichicon’s RKS series. It delivers 180 µF at 16 V with low equivalent series resistance (ESR) and high ripple-current capability for general-purpose electronic designs.

Designed for robust thermal and electrical performance, this capacitor supports an operating temperature range of –55°C to 125°C and a rated endurance of 3000 hours at 125°C, making it suitable for demanding board-level power and decoupling applications.

Key Features

• Capacitance & Voltage — 180 µF nominal capacitance with a rated voltage of 16 V and capacitance tolerance of −20% to +20%.
• Conductive Polymer Construction — Solid polymer electrolyte for stable electrical characteristics and reduced loss compared with traditional liquid electrolytes.
• Low ESR — ESR of 20 mΩ measured at 20°C/100 kHz, supporting efficient charge/discharge cycles and minimizing dissipation.
• High Ripple Current — Low-frequency ripple current of 210 mA at 120 Hz and high-frequency ripple current of 2.1 A at 300 kHz to support switching and high-frequency circuits.
• Loss Tangent — tan δ of 0.12 (measured at 20°C, 120 Hz) for predictable AC performance.
• Leakage Current — Typical leakage current listed as 144 µA, enabling reliable hold and low standby loss under rated conditions.
• Thermal Endurance — Rated life of 3000 hours at 125°C, with specified endurance performance for capacitance, tan δ and ESR after testing.
• Surface-Mount Package — Compact radial can SMD: φ10 × 10L (10 mm diameter × 10 mm length) with embossed carrier taping and moisture-proof packing for automated assembly.
• Manufacturing Compatibility — Lead-free reflow soldering condition compatibility (peak temperature noted in series data), supporting standard SMD assembly processes.
• Regulatory — RoHS compliant.

Typical Applications

• General Purpose Electronics — Intended for a wide range of board-level applications where 180 µF/16 V SMD capacitance and robust thermal endurance are required.
• Power Conditioning — Used where stable capacitance, low ESR (20 mΩ), and high ripple-current handling (up to 2.1 A at high frequency) help maintain voltage stability on power rails.
• High-Temperature Environments — Suitable for assemblies that require component reliability across −55°C to 125°C and long-life performance (3000 h at 125°C).

Unique Advantages

• Low-loss polymer electrolyte: Conductive polymer construction yields low tan δ (0.12) for efficient AC performance and predictable behavior in filtering and decoupling roles.
• High ripple-current capability: 2.1 A at high frequency and 210 mA at low frequency minimize heating and extend usable life in switching applications.
• Compact SMD form factor: φ10 × 10L package with embossed carrier taping and moisture-proof packing streamlines automated placement and storage handling.
• High-temperature endurance: 3000-hour rated life at 125°C supports long-term reliability in thermally demanding assemblies.
• Low ESR for improved efficiency: 20 mΩ ESR at 100 kHz reduces power loss and supports tight voltage regulation on high-current rails.
• Compliance and assembly readiness: RoHS compliant and compatible with lead-free reflow profiles stated for the RKS series, aiding regulatory and manufacturing workflows.
