RKS1C331MCNAJLGS

The RKS1C331MCNAJLGS is a surface-mount conductive polymer aluminum electrolytic capacitor from Nichicon’s RKS series. It delivers 330 µF capacitance at a 16 V rating in a compact radial can SMD package, designed for general-purpose power filtering and decoupling in compact electronic assemblies.

Key value comes from a low ESR construction and high allowable ripple current, combined with a long load life (3000 hours at 125°C) and a wide operating temperature range, enabling reliable performance in thermally demanding environments.

Key Features

• Capacitance & Tolerance — 330 µF nominal capacitance with tolerance ±20% (–20% to +20%) measured at 20°C, 120 Hz.
• Rated Voltage — 16 V DC rating suitable for a variety of low-voltage power rails.
• Low ESR — Equivalent series resistance of 20 mΩ at 20°C / 100 kHz, supporting low-loss operation at high frequency.
• High Ripple Current Capability — 200 mA at 120 Hz (low frequency) and 2 A at 300 kHz (high frequency) for improved thermal and ripple handling.
• Tangent of Loss Angle (tan δ) — 0.12 measured at 20°C / 120 Hz, supporting stable AC performance.
• Leakage Current — Specified leakage current of 264 µA.
• Long Endurance — Rated for 3000 hours at 125°C under rated voltage, supporting extended operation in elevated temperatures.
• Robust Temperature Range — Operates from –55°C to +125°C to cover demanding thermal environments.
• Compact SMD Package — Radial, can-style SMD package with nominal dimensions φ10 × 12.4 mm (height 12.4 mm, diameter 10 mm) and surface-mount mounting type.
• Production & Packaging — Mass production status with embossed carrier taping and moisture-proof packing for SMT assembly.
• RoHS Compliant — Meets RoHS requirements as stated for the RKS series.

Typical Applications

• Power supply output smoothing — Ideal for smoothing and stabilizing low-voltage DC outputs where compact size and high ripple capability are required.
• Decoupling for DC–DC converters — Low ESR and high-frequency ripple handling make it suitable for converter output and post-regulation decoupling.
• Embedded and industrial electronics — Supports general-purpose power conditioning in compact, thermally stressed assemblies.
• SMD power modules — Surface-mount radial can package and tape-and-reel style packing facilitate automated pick-and-place assembly for module integration.

Unique Advantages

• Improved thermal endurance: 3000-hour load life at 125°C provides longevity for designs exposed to high operating temperatures.
• High ripple handling in a small footprint: 2 A high-frequency ripple current capability combined with a φ10 × 12.4 mm package helps reduce thermal stress without increasing board area.
• Low-loss AC performance: 20 mΩ ESR at 100 kHz and tan δ of 0.12 at 120 Hz reduce power dissipation and improve efficiency in high-frequency circuits.
• Surface-mount, assembly-ready packaging: Embossed carrier taping and moisture-proof packing simplify SMT production flow and storage.
• Wide operating temperature span: –55°C to +125°C supports designs that must operate reliably across harsh thermal conditions.
• Regulatory compliance: RoHS compliance helps meet environmental and supply-chain requirements.
