The RKS1C331MCNAHFGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor from Nichicon’s RKS series. It delivers 330 µF capacitance at a 16 V rating in a compact φ8 × 6.7 mm SMD can package intended for general-purpose applications.

Designed for elevated-temperature operation and high ripple environments, this part combines low ESR and specified high-frequency ripple capability with a 3000-hour endurance rating at 125°C.

Key Features

• Capacitance & Tolerance — 330 µF nominal with tolerance of -20% to +20% (±20% at 120 Hz, 20°C).
• Rated Voltage — 16 V DC rating suitable for a range of low-voltage power designs.
• Conductive Polymer Aluminum Construction — Solid electrolyte construction as specified in the product series, offering stable performance suited to SMD mounting.
• Low Equivalent Series Resistance (ESR) — 30 mΩ specified at 20°C / 100 kHz to support efficient high-frequency operation.
• High Ripple Current Capability — 160 mA at 120 Hz (low frequency) and 1.6 A at 300 kHz (high frequency), enabling improved ripple handling.
• Leakage Current — Specified leakage current of 264 µA under rated conditions.
• Endurance and Temperature Range — Rated for 3000 hours at 125°C; operating temperature range from -55°C to +125°C.
• SMD Can Package & Size — Radial, can-type SMD package with dimensions φ8 mm × 6.7 mm (L), suitable for embossed carrier taping and moisture-proof packing.
• Reflow Compatibility — SMD type compatible with lead-free reflow soldering conditions up to a 260°C peak (per series soldering guidelines).
• RoHS Compliant — Manufactured in compliance with RoHS requirements.

Typical Applications

• Power Supply Filtering — 330 µF capacitance combined with low ESR and 1.6 A high-frequency ripple rating makes this part suitable for smoothing and decoupling in compact power modules.
• High-Temperature Electronics — Rated endurance of 3000 hours at 125°C and an operating range of -55°C to 125°C support use in elevated-temperature environments.
• Compact SMD Designs — φ8 × 6.7 mm can package and embossed carrier taping packaging fit space-constrained surface-mount assemblies requiring bulk capacitance.

Unique Advantages

• Low ESR for Efficient High-Frequency Performance: 30 mΩ at 100 kHz reduces losses and supports effective ripple current handling in high-frequency circuits.
• High Ripple Current Capacity: Specified 160 mA (120 Hz) and 1.6 A (300 kHz) ratings provide measurable allowance for both low- and high-frequency ripple conditions.
• Extended High-Temperature Endurance: 3000 hours at 125°C offers a verifiable life metric for designs exposed to sustained elevated temperatures.
• Compact Surface-Mount Can: φ8 × 6.7 mm SMD can delivers substantial capacitance in a small footprint with industry-standard embossed carrier taping and moisture-proof packing.
• Assembly-Ready: Lead-free reflow compatibility to a 260°C peak supports modern PCB assembly processes.
• Regulatory Compliance: RoHS compliance supports environmentally restricted product requirements.
