RKS1C331MCNAJJGS

The RKS1C331MCNAJJGS from Nichicon is a surface-mount conductive polymer aluminum solid electrolytic capacitor with 330 µF capacitance and a 16 V rated voltage. Designed for general-purpose power applications, it delivers high capacitance in a compact φ10 × 10 mm SMD can.

Key performance attributes include low ESR (20 mΩ at 100 kHz, 20°C), high allowable ripple current (2.1 A at 300 kHz), and extended endurance (3000 hours at 125°C), making it suitable for demanding power-filtering and high-ripple environments across industrial and electronic equipment.

Key Features

• High Capacitance — 330 µF nominal capacitance with tolerance of -20% to +20% measured at 20°C, 120 Hz, providing bulk energy storage for decoupling and smoothing.
• Low ESR & High Ripple Handling — ESR of 20 mΩ (at 100 kHz, 20°C) and high-frequency ripple current rating of 2.1 A (at 300 kHz) reduce voltage ripple and thermal stress under dynamic loads.
• Solid Electrolyte Construction — Conductive polymer aluminum solid electrolytic design for stable electrical characteristics and improved high-frequency performance.
• Robust Thermal Endurance — Rated operating temperature range from -55°C to 125°C and life/endurance of 3000 hours at 125°C under rated voltage.
• Leakage & Dissipation Characteristics — Specified leakage current of 264 µA and tan δ of 0.12 (measured at 20°C, 120 Hz) for predictable performance in bias conditions.
• SMD Package & Assembly — Compact φ10 × 10 mm SMD radial can (package case: Radial, Can - SMD) supplied in embossed carrier taping with moisture-proof packing, compatible with lead‑free reflow (260°C peak) processes.
• Compliance — RoHS-compliant construction for regulatory alignment in lead-free designs.

Typical Applications

• Power Supply Filtering — Bulk smoothing and decoupling where low ESR and high ripple capacity reduce output ripple and improve regulator stability.
• DC‑DC Converters — Input/output filtering in converter stages that require compact capacitors with high ripple tolerance and stable high-frequency behavior.
• Industrial Electronics — Power conditioning in industrial control and instrumentation that demand wide temperature operation and extended endurance at elevated temperatures.

Unique Advantages

• Compact high-capacitance SMD form factor: 330 µF in a φ10 × 10 mm package minimizes board area while providing bulk energy storage.
• Superior ripple performance: 2.1 A high-frequency ripple rating (300 kHz) combined with 20 mΩ ESR helps lower heating and improves reliability under dynamic loads.
• Extended high-temperature life: 3000 hours at 125°C ensures long-term performance in thermally aggressive environments.
• Predictable electrical behavior: Specified tan δ, leakage current, and ESR measurements (20°C) enable confident simulation and margining in designs.
• Assembly-ready packaging: Embossed carrier taping and moisture-proof packing support automated SMD assembly and lead‑free reflow processes.
• Regulatory readiness: RoHS compliance supports usage in lead‑free product platforms.
