RKS1D330MCNAFGGS

The RKS1D330MCNAFGGS is a surface-mount conductive-polymer aluminum solid electrolytic capacitor in Nichicon’s RKS series. It delivers 33 µF capacitance at a 20 V rating in a compact φ6.3 × 7.7 mm SMD can, optimized for applications requiring low ESR and high ripple handling in constrained PCB real estate.

Engineered for high-temperature endurance, the part is specified for operation from −55 °C to 125 °C with a rated load life of 3000 hours at 125 °C, making it suitable for robust electronic power and thermal environments where sustained stability and high-frequency performance matter.

Key Features

• Dielectric / Core: Conductive-polymer aluminum solid electrolytic construction for stable electrical performance and low equivalent series resistance.
• Capacitance & Tolerance: 33 µF nominal with ±20% tolerance at 120 Hz, 20 °C for predictable bulk and decoupling behavior.
• Rated Voltage: 20 V DC rating suitable for common low-voltage power domains.
• Low ESR / High-Frequency Performance: ESR of 30 mΩ measured at 100 kHz (20 °C) and tan δ of 0.12 at 120 Hz (20 °C), enabling efficient high-frequency filtering and reduced dissipation.
• High Allowable Ripple Current: 140 mA at 120 Hz (low frequency) and 1.4 A at 300 kHz (high frequency) for effective ripple absorption in switching power stages.
• Leakage Current: Specified leakage current up to 100 µA (after 2 minutes’ application of rated voltage), facilitating long-term stability in bias circuits.
• Thermal & Endurance: Operating range −55 °C to 125 °C with a rated lifetime of 3000 hours at 125 °C; endurance and damp-heat characteristics are defined by the series specification.
• Assembly & Soldering: Surface-mount radial can (SMD) package with reflow capability up to a 260 °C peak (lead-free reflow conditions supported); available in embossed carrier taping with moisture-proof packing for SMT production flows.
• Compliance: RoHS compliant under the listed directive references.

Typical Applications

• SMD power modules: Low ESR and high ripple-current capability make this capacitor appropriate for output filtering and energy storage in compact switching regulators and power module assemblies.
• DC–DC converters: Use for decoupling and smoothing at converter outputs where high-frequency ripple suppression and thermal endurance are required.
• Industrial electronics: Suited to ruggedized control electronics and instrumentation that operate across wide temperature ranges and require long-term stability at elevated temperatures.

Unique Advantages

• Low dissipation at high frequency: 30 mΩ ESR at 100 kHz and a tan δ of 0.12 support efficient high-frequency filtering with reduced heat generation.
• High ripple capability: 1.4 A allowable ripple current at 300 kHz enables reliable performance in switching applications and reduces the need for oversized capacitance.
• High-temperature endurance: Rated 3000 hours at 125 °C for sustained operation in hot environments and improved long-term reliability.
• SMT-ready packaging: Compact φ6.3 × 7.7 mm can, embossed carrier taping and moisture-proof packing simplify automated assembly and handling.
• Manufacturing resilience: Lead-free reflow compatibility up to 260 °C supports modern Pb-free assembly processes.
• Regulatory compliance: RoHS compliance supports use in products requiring restricted-substance conformance.
