RKS1C331MCNAHGGS

The RKS1C331MCNAHGGS from Nichicon is a surface-mount conductive polymer aluminum solid electrolytic capacitor in the RKS series. It delivers 330 µF capacitance at a 16 V rating in a compact φ8 × 7.7 mm SMD can package designed for general-purpose electronic assemblies.

Engineered for applications that require low equivalent series resistance and substantial ripple handling, this capacitor combines a wide operating temperature range (−55°C to 125°C) with a 3000-hour endurance at 125°C for reliable long-term performance.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a rated voltage of 16 V and tolerance of −20% to +20%.
• Conductive Polymer Electrolyte — Solid conductive polymer construction for stable electrical characteristics and long life as specified for the RKS series.
• Low ESR — ESR of 30 mΩ measured at 20°C and 100 kHz, supporting efficient high-frequency performance.
• High Ripple Current Capability — Rated ripple currents of 160 mA at 120 Hz (low frequency) and 1.6 A at 300 kHz (high frequency) to handle demanding ripple loads.
• Loss Angle (tan δ) — tan δ of 0.12 measured at 20°C and 120 Hz, supporting predictable AC loss behavior.
• Leakage Current — Specified leakage current of 264 µA after rated voltage application.
• Robust Temperature & Lifetime — Operating range −55°C to 125°C with a rated load life of 3000 hours at 125°C.
• SMD Can Package — Radial can SMD package, size φ8 × 7.7 mm, supplied in embossed carrier taping with moisture-proof packing for automated assembly.
• RoHS Compliant — Meets RoHS directive requirements as indicated for the series.
• Production Status — Product is in mass production for immediate procurement.

Typical Applications

• General-purpose electronic assemblies — Suitable where a compact SMD electrolytic capacitor is required for bulk capacitance and energy storage.
• Power supply filtering and decoupling — Low ESR (30 mΩ @100 kHz) and high ripple current ratings support filtering in compact power circuits.
• High-frequency circuits — 1.6 A allowable ripple current at 300 kHz and low loss tangent make it appropriate for circuits with significant high-frequency content.

Unique Advantages

• High ripple tolerance: Rated ripple currents of 160 mA (120 Hz) and 1.6 A (300 kHz) reduce overheating risk in ripple-intensive applications.
• Low ESR for efficient filtering: 30 mΩ ESR at 100 kHz improves transient response and reduces power dissipation in high-frequency environments.
• Extended high-temperature life: 3000 hours endurance at 125°C supports reliable operation in elevated-temperature designs.
• Compact SMD can format: φ8 × 7.7 mm package and embossed carrier taping enable high-density automated assembly and streamlined BOM integration.
• Predictable AC behavior: Specified tan δ (0.12 at 20°C, 120 Hz) and defined leakage current (264 µA) simplify design margin calculations.
• RoHS-compliant manufacturing: Provides regulatory alignment for environmentally conscious product designs.
