RKS1C331MCNAHHGS

The RKS1C331MCNAHHGS is a surface‑mount conductive polymer aluminum solid electrolytic capacitor designed for general‑purpose SMD applications. It delivers 330 µF of capacitance at a 16 V rating with a conductive polymer dielectric to provide low equivalent series resistance and stable high‑frequency performance.

Key value comes from its combination of high capacitance, low ESR (30 mΩ at 100 kHz), and rated endurance of 3000 hours at 125°C, making it suitable where compact bulk capacitance and reliable ripple handling are required on the board.

Key Features

• Capacitance & Tolerance — 330 µF with ±20% tolerance (measured at 120 Hz, 20°C), providing bulk charge storage for SMD power rails and decoupling.
• Rated Voltage — 16 V DC rated voltage for mid‑voltage power applications.
• Low ESR & Loss — ESR of 30 mΩ at 100 kHz and tan δ of 0.12 (20°C, 120 Hz) for efficient high‑frequency operation and reduced heating.
• High Ripple Current Capability — Low‑frequency ripple current of 160 mA at 120 Hz and high‑frequency ripple current of 1.6 A at 300 kHz to support switching regulator and high‑speed load transients.
• Temperature & Endurance — Wide operating temperature range from −55°C to +125°C and a rated life of 3000 hours at 125°C for robust thermal performance.
• Leakage & Reliability — Specified leakage current of 264 µA and conductive polymer chemistry for stable long‑term behavior under load.
• Compact SMD Can Package — Radial, can‑style SMD package with dimensions φ8 × 8.7 mm, supplied in embossed carrier taping with moisture‑proof packing for automated placement.
• RoHS Compliance — Compliant to the RoHS directive as specified in the product datasheet.

Typical Applications

• General‑purpose power decoupling — Bulk and smoothing capacitance on board power rails where 330 µF at 16 V and low ESR improve transient response.
• Switching regulator support — Input and output filtering in DC‑DC converters that require high ripple current capability and low loss at high frequency.
• Compact SMD power modules — Space‑constrained modules that need a high‑capacitance SMD can with reliable thermal endurance up to 125°C.

Unique Advantages

• Low ESR for efficient operation: 30 mΩ at 100 kHz reduces power dissipation and improves converter stability in high‑frequency circuits.
• High ripple handling: 1.6 A at 300 kHz (high frequency) and 160 mA at 120 Hz (low frequency) allow the capacitor to manage both switching and line ripple effectively.
• High temperature endurance: Rated 3000 hours at 125°C, providing predictable lifetime performance in elevated temperature environments.
• Solid conductive polymer chemistry: Offers stable leakage and ESR characteristics compared with some wet electrolytes, supporting long‑term reliability.
• Automated assembly ready: Embossed carrier taping and moisture‑proof packing streamline surface‑mount placement and reflow processing.
