RKS1C331MCNAHJGS

The RKS1C331MCNAHJGS is a surface-mount conductive polymer aluminum electrolytic capacitor offering 330 µF capacitance at a 16 V rating. It combines low equivalent series resistance and high allowable ripple current with a compact SMD can package for space-constrained power designs.

Designed for general-purpose power applications, this part delivers long endurance (3000 hours at 125°C) and RoHS-compliant construction, making it suitable for demanding thermal and high-frequency environments.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a 16 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• Low ESR — 25 mΩ equivalent series resistance measured at 20°C/100 kHz for reduced loss and improved high-frequency performance.
• High Ripple Current — Low-frequency ripple current 170 mA (120 Hz) and high-frequency ripple current 1.7 A (300 kHz) to support switching regulators and DC–DC converters.
• Loss Angle (tan δ) — tanδ of 0.12 at 20°C, 120 Hz, enabling predictable dissipation characteristics.
• Leakage Current — 264 µA leakage current (specified condition), supporting stable bias performance.
• Wide Operating Temperature & Endurance — Rated for −55°C to +125°C with a rated load life of 3000 hours at 125°C.
• Compact SMD Can — φ8×10L package (SizeDimension L: 1 × D: 0.8 cm) in an SMD radial-can format for PCB space savings and automated assembly.
• Packaging — Supplied in embossed carrier taping with moisture-proof packing for reflow-friendly handling.
• RoHS Compliant — Meets RoHS directive requirements as specified in the product documentation.

Typical Applications

• Power supply filtering and smoothing — Low ESR (25 mΩ) and high ripple capability (1.7 A at 300 kHz) make this capacitor suitable for bulk smoothing on 16 V rails in compact power supplies.
• Switch-mode DC–DC converters — High-frequency ripple handling and conductive polymer construction support stable performance with switching regulators.
• Decoupling for high-current rails — The combination of low loss (tanδ 0.12) and low leakage supports decoupling in dense power distribution networks.

Unique Advantages

• High ripple tolerance: Rated for 1.7 A high-frequency ripple current to handle demanding switching environments and reduce thermal stress.
• Low dissipation footprint: 25 mΩ ESR at 100 kHz and tanδ 0.12 yield lower power loss and improved efficiency in high-frequency circuits.
• Long-term reliability: 3000 hours endurance at 125°C provides predictable life performance for thermal-stressed designs.
• SMD-friendly packaging: φ8×10L SMD can and embossed carrier taping enable automated assembly and moisture-controlled storage.
• RoHS compliance: Meets regulatory requirements for lead-free production environments.
• Reflow-capable construction: Designed for lead-free reflow processes up to the specified 260°C peak soldering conditions in the product documentation.
