RKS1K330MCNAJJGS

The RKS1K330MCNAJJGS is a surface-mount conductive polymer aluminum electrolytic capacitor offering 33 µF capacitance at an 80 V rating. It combines low ESR and high allowable ripple current in a compact radial can SMD package for general-purpose electronic applications.

Designed for demanding thermal and ripple environments, the part delivers a wide operating range from –55°C to 125°C and a rated load life of 3000 hours at 125°C, making it suitable where long-term stability and efficient power handling are required.

Key Features

• Core Construction Conductive polymer aluminum solid electrolyte for stable performance and low equivalent series resistance.
• Rated Electricals 33 µF capacitance with ±20% tolerance and 80 V rated voltage for mid‑to‑high voltage SMD designs.
• Low Loss / High Frequency Performance tanδ 0.12 (measured at 20°C, 120 Hz) and ESR of 30 mΩ at 20°C/100 kHz to support efficient AC ripple handling.
• Ripple Current Capability Low-frequency ripple current 140 mA (120 Hz) and high-frequency ripple current 1.4 A (300 kHz) for robust filtering and decoupling.
• Leakage Current Specified leakage current of 132 µA after rated voltage application.
• Reliability & Endurance Rated for 3000 hours at 125°C; meets endurance, damp heat, and soldering heat resistance criteria as specified for the series.
• Package & Mounting Surface-mount radial can (φ10 × 10 mm) supplied in embossed carrier taping with moisture-proof packing for automated assembly.
• Assembly Compatibility SMD type compatible with lead-free reflow soldering conditions up to a 260°C peak as specified for the series.
• Environmental Compliance RoHS compliant.

Typical Applications

• General‑Purpose Electronics — Designed for general-purpose circuits requiring a compact SMD aluminum polymer capacitor.
• Power Filtering and Decoupling — Low ESR (30 mΩ @100 kHz) and high allowable ripple current support smoothing and decoupling in power stages.
• Industrial and Telecom Equipment — Wide operating range (–55°C to 125°C) and 3000-hour life at 125°C suit long-life industrial or communication power modules.

Unique Advantages

• Low ESR for improved efficiency: 30 mΩ ESR at 100 kHz reduces losses and heat generation in high-frequency power circuits.
• High ripple handling: 1.4 A high-frequency ripple rating and 140 mA low-frequency rating enable reliable filtering under varying load conditions.
• Extended temperature and life rating: –55°C to 125°C operating range and 3000 hours endurance at 125°C deliver predictable long-term performance in thermally demanding environments.
• SMD radial-can compactness: φ10 × 10 mm package minimizes board footprint while remaining compatible with automated assembly and moisture-proof tape packaging.
• Reflow-compatible assembly: Series-specified lead-free reflow up to 260°C peak enables standard surface-mount manufacturing flows.
• Regulatory compliance: RoHS compliance ensures suitability for restricted-substance requirements.
