RKS1H180MCNAFEGS

The RKS1H180MCNAFEGS from Nichicon is a surface-mount conductive-polymer aluminum solid electrolytic capacitor specified at 18 µF and 50 V. It delivers low equivalent series resistance and defined ripple-handling capability in a compact SMD can (φ6.3 × 5.8 mm).

Engineered for demanding power-electronics environments, this part is suited to applications that require stable capacitance, low loss (tan δ 0.12 at 20°C/120 Hz), and extended high-temperature endurance (3000 hours at 125°C).

Key Features

• Electrical Performance — 18 µF nominal capacitance with tolerance ±20% (measured at 20°C, 120 Hz) and rated voltage 50 V.
• Low Loss & Leakage — tan δ = 0.12 (20°C, 120 Hz) and leakage current specified at 100 µA, supporting reliable circuit behavior under rated conditions.
• Low ESR & High Ripple Capability — ESR 80 mΩ measured at 20°C/100 kHz, with ripple current ratings of 75 mA at 120 Hz (low frequency) and 750 mA at 300 kHz (high frequency) for effective filtering and decoupling.
• High Temperature Endurance — Rated operating range −55°C to 125°C with a load life of 3000 hours at 125°C, suitable for sustained elevated-temperature operation.
• SMD Package & Reflow Tolerance — Surface-mount radial can (φ6.3 × 5.8 mm); supplied in embossed carrier taping with moisture-proof packing and compatible with lead‑free reflow profiles up to 260°C peak per manufacturer guidance.
• Manufacturing & Assembly — Designed for automated placement on PCB land size 6.6 × 6.6 mm, simplifying integration into production workflows.
• Compliance — Part of a series with RoHS directive compliance noted in the manufacturer documentation.

Typical Applications

• Power rail decoupling — Low ESR and high ripple handling make this capacitor suitable for smoothing and stabilizing DC-DC converter outputs and local power rails.
• Input/output filtering for power modules — Compact SMD can and high-temperature endurance support filtering at module inputs/outputs in industrial and telecom equipment.
• Bulk and hold-up capacitance — Defined leakage and endurance characteristics enable reliable use as bulk or hold‑up capacitors in constrained board space.
• High-frequency bypassing — ESR specified at 100 kHz and ripple rating at 300 kHz support high-frequency bypass and noise suppression tasks.

Unique Advantages

• Measurable low-loss behavior: tan δ = 0.12 at 20°C/120 Hz provides predictable dissipation for thermal and stability calculations.
• Quantified ripple capability: Separate low‑ and high‑frequency ripple current ratings (75 mA @ 120 Hz; 750 mA @ 300 kHz) enable selection based on the application’s spectral ripple profile.
• Extended high-temperature life: 3000 hours at 125°C gives a clear reliability metric for high-temperature deployments.
• Compact SMD footprint: φ6.3 × 5.8 mm can size and defined PCB land dimensions (6.6 × 6.6 mm) reduce board area while remaining compatible with automated assembly.
• Reflow-capable assembly: Specified for lead‑free reflow up to 260°C peak, facilitating modern Pb-free manufacturing processes.
• Documented leakage behavior: Leakage current specification (100 µA) and conditioning notes support predictable bias‑dependent performance.
