RKS1C331MCNAFGGS

The RKS1C331MCNAFGGS from Nichicon is a surface-mount conductive polymer aluminum solid electrolytic capacitor optimized for general-purpose power applications. It delivers 330 µF at 16 V in a compact φ6.3 × 7.7 mm SMD can, combining high capacitance density with low impedance for demanding board-level power decoupling and smoothing.

Key value propositions include low ESR (30 mΩ at 100 kHz), high allowable ripple current (1.5 A at high frequency), extended thermal endurance (3000 h at 125°C), and RoHS compliance—making it suitable where long-term thermal stability and low-loss performance are required.

Key Features

• Capacitance & Voltage — 330 µF rated at 16 V with a capacitance tolerance of −20% to +20% (measured at 20°C, 120 Hz).
• Low Loss / Low ESR — ESR specified at 30 mΩ (20°C, 100 kHz) and tanδ 0.12 (20°C, 120 Hz), supporting lower voltage drop and improved transient response.
• High Ripple Handling — Low-frequency ripple current 150 mA (120 Hz) and high-frequency ripple current 1.5 A (300 kHz) for robust power-rail filtering under switching conditions.
• Leakage Current — Specified leakage current of 264 µA, measured per product conditions.
• Thermal Endurance — Rated operating temperature −55°C to +125°C with a load-life specification of 3000 hours at 125°C, supporting long-term high-temperature operation.
• SMD Package & Reflow Compatibility — Radial can SMD (φ6.3 × 7.7 mm) supplied in embossed carrier taping with moisture-proof packing; compatible with lead-free reflow soldering conditions up to a 260°C peak as described in the series specification.
• Environmental Compliance — RoHS compliant.

Typical Applications

• Power Supply Filtering — Ideal for output smoothing and bulk decoupling on DC–DC converters and regulator outputs where low ESR and high ripple handling improve stability and transient response.
• Switching Power Modules — Suited to compact switching modules that require high capacitance in a small footprint and robust high-frequency ripple performance.
• Industrial Electronics — Useful in industrial control and instrumentation circuits that operate across wide temperatures and demand long endurance at elevated temperatures.
• Communications and Networking Equipment — Provides board-level bulk decoupling and noise suppression in systems with high switching activity and fast transient currents.

Unique Advantages

• High Capacitance in a Compact SMD Can: 330 µF in a φ6.3 × 7.7 mm package reduces board area while providing significant bulk energy storage.
• Low Impedance at High Frequency: 30 mΩ ESR at 100 kHz and 1.5 A high-frequency ripple current capability improve voltage stability in switching environments.
• Extended High‑Temperature Life: 3000 hours endurance at 125°C offers predictable long-term performance in thermally challenging designs.
• Reflow-Ready Packaging: Embossed carrier taping and moisture-proof packing simplify automated assembly and reflow processing up to specified peak temperatures.
• Measured, Verifiable Specs: Key parameters (tanδ, leakage, ESR, ripple current) are specified with measurement conditions for engineering validation.
