The RKS1H330MCNAHHGS is a surface-mount conductive-polymer aluminum electrolytic capacitor in the Nichicon RKS series, offering 33 µF capacitance at a 50 V rating. It pairs low equivalent series resistance with high allowable ripple current and extended endurance, making it suitable for demanding power and high-frequency smoothing applications.

Designed for automated assembly, the part ships in embossed carrier taping with moisture-proof packing and supports lead-free reflow soldering profiles specified in the datasheet.

Key Features

• Capacitance & Voltage — 33 µF nominal capacitance with a rated voltage of 50 V and tolerance of −20% to +20% (measured at 20°C, 120 Hz).
• Low Loss and Low ESR — tanδ of 0.12 (20°C, 120 Hz) and ESR of 30 mΩ measured at 20°C/100 kHz, allowing efficient high-frequency performance.
• High Ripple Handling — Low-frequency ripple current 160 mA (120 Hz) and high-frequency ripple current 1.6 A (300 kHz) for power rail smoothing and decoupling.
• Leakage and Endurance — Leakage current specified at 100 µA and rated life of 3000 hours at 125°C, enabling reliable operation in elevated temperature environments.
• Temperature Range — Operates from −55°C to +125°C to cover wide thermal conditions in industrial and telecommunications equipment.
• SMD Package & Assembly — Radial, can-style SMD package (φ8 × 8.7 mm) with recommended land size L: 8.3 × W: 8.3 mm; compatible with lead‑free reflow soldering up to the datasheet profile (peak 260°C) per specified pre-heat and peak conditions.
• Compliance & Packaging — RoHS compliant; supplied in embossed carrier taping with moisture-proof packing for SMT production lines.

Typical Applications

• DC–DC converter output filtering — Low ESR and high-frequency ripple capability support tight voltage regulation and transient suppression on power rails.
• Power supply bulk and smoothing — 33 µF at 50 V with 1.6 A HF ripple current is suitable for bulk decoupling where high ripple handling is required.
• Industrial and telecommunications equipment — Wide operating temperature (−55°C to +125°C) and 3000 h endurance at 125°C support long-term operation in thermally challenging environments.
• Compact SMD designs — Small φ8 × 8.7 mm can-style SMD package fits space-constrained boards while supporting automated reflow assembly.

Unique Advantages

• Low ESR for high-frequency performance: 30 mΩ (100 kHz) ESR enables efficient high-frequency decoupling and reduced losses in power circuits.
• High ripple tolerance: 1.6 A ripple at 300 kHz and 160 mA at 120 Hz allow robust handling of both switching and line-frequency ripple components.
• Extended thermal endurance: 3000 hours at 125°C provides predictable lifetime behavior for designs exposed to elevated temperatures.
• Reflow-ready SMD format: Embossed carrier taping, moisture-proof packing, and compatibility with lead-free reflow profiles simplify assembly and supply-chain handling.
• Compact footprint: φ8 × 8.7 mm package with specified land pattern supports high-density board layouts without sacrificing performance.
• Verified leakage performance: Leakage current spec of 100 µA supports predictable bias conditions after voltage application.
